THIS DRAMA IS FICTION

THE CHARACTERS, BUSINESSES, LOCATIONS,

RELIGIONS, AND EVENTS AREN'T REAL

COVID-19 MEASURES WERE FOLLOWED,

IN MOST SCENES WITH ANIMALS

I can see the head.

Push a little harder.

Give me another push.

Is the baby okay?

Well done.

He looks just like me.

He is indeed Han Seo-jun Junior.

You should hold him too. He's our baby.

MOUSE

Did you have a nightmare?

A nightmare?

What am I doing here?

I found you when I went over

to give you a receipt.

You're lucky I found you.

It could've gotten serious.

I was going to call the police, but

It was your son, right?

You're mistaken.

He was just trying to stop me

from hurting myself.

So don't call the police.

Okay? Don't.

Thanks.

Where's my cell phone?

I brought it with me.

Here you go.

MOM

Ba-reum.

Ba-reum.

Are you okay, Ba-reum?

Ba-reum, wake up.

Two people down.

Send an ambulance as soon as possible.

-Oh, no.

-The address is

Wake up, Ba-reum.

-It's 356-4, Gudong-ro.

-Detective Ko, please help him.

We're at the rooftop

of the house with the green gate.

What do we do?

Where's Han-guk?

-Han

-Yes, Han-guk.

Where is Han-guk, you b*stard?

What?

No.

You scumbag. Wake up!

Where's the boy?

A police officer and the suspect

of the Moojin serial murders

got into a physical fight

tonight at around 9 p.m.

They're seriously injured

and were transferred to the hospital.

Breaking news. A man in his 20s

who got into a physical fight

with the suspect of the serial murders

in Moojin who claims to be God

turned out to be Officer Jung Ba-reum

of Gudong Police Substation.

You cannot go in. Stop her.

Wait.

He's going into surgery. Call the OR.

Mr. Jung Ba-reum is on his way to the OR.

Officer Jung Ba-reum,

who is in a critical state

from the blunt trauma

to the head by the suspect,

is the main witness

of Gudong's old lady m*rder case.

The police assume that the suspect

broke into his house to silence him.

This is the frontal lobe.

The compound depressed skull fracture

is quite serious.

He is showing no reaction to any pain,

so I doubt the prognosis will be good.

What about Sung Yo-han?

As the b*llet penetrated his abdomen,

it seriously damaged the adjacent organs.

I doubt he'll survive.

But we can't know for sure

until after the surgery.

Sung Yo-han

-Where is Sung Yo-han?

-Pardon?

Where is my son?

He's in such a critical state,

so he's being operated on.

Please calm down and sign

How bad is it?

I can't tell you for sure yet.

Did you sh**t him?

My poor Yo-han

The poor boy

Did you sh**t him?

Poor boy?

Your son?

What about Officer Jung?

His skull is fractured

because your son hit him with a hammer,

and he is about to die from brain damage.

But you pity your son?

How will he pay for it?

How?

HEADHUNTER THE m*rder*r

LIKE FATHER, LIKE SON

Where's Han-guk? Have you found him yet?

Have you found the boy yet?

We searched Sung Yo-han's house

and the vicinity, but it was a bust.

He must've moved the boy then.

-What?

-What do you mean?

Detective Shin and I stopped

Sung Yo-han's car and searched his trunk.

But the boy wasn't there.

I think we found his car.

Damn.

Give it to me.

He probably switched cars here.

Check every camera around here

and get a list of cars

that drove by around the same time.

-Check stolen cars, too.

-Okay. Let's go.

You must go through every car

that comes out of this alley.

This car too.

-We found it.

-Put it up on the large screen.

The plate number is 10MO 4219.

Let's track 10MO 4219.

Check every camera that caught that car.

We lost him from there.

Where is that place? Pull up the map.

There's a nursing home

that closed 20 years ago there.

Move quickly.

Hurry up.

Hurry!

Detective Ko. Did you find something?

Those are the clothes from his suitcase.

-This is the place.

-I'll go tell them.

What is this?

Detective Ko, get over here.

Check for blood.

Call the forensics team.

He couldn't have gone far

with the young boy.

It's possible he dumped

the boy's body nearby.

Search the building

and the vicinity thoroughly.

While the surgery is being done on the man

who is considered the suspect

in the Moojin serial murders,

the police are going all out

to look for Kim Han-guk.

They'll do a briefing

in the lobby. Let's go!

Sung Yo-han's surgery was successful.

We removed parts of his organs

that were severely damaged.

We had to clean his abdominal cavity

and conduct a necrotomy.

How is Officer Jung Ba-reum doing?

His frontal lobe and temporal lobe

are severely damaged

from brain ischemia

caused by increased brain pressure.

The brain pressure kept rising,

so an emergency operation was being done

to avoid brain herniation.

But due to severe cerebral hemorrhage,

we had to stop the surgery.

His skull is fractured

because your son hit him with a hammer,

and he is about to die from brain damage.

I felt bad for you because you were

in pain for being a m*rder*r's son.

I saw myself in you.

That's why I

You won't be forgiven even after death.

This is all I can do for you.

There is no progress

in finding Kim Han-guk,

and Officer Jung Ba-reum's surgery

has been stopped

because he's in a critical state.

People are criticizing

the government regarding this case.

According to a survey,

the approval rating for the president

has dropped by 40 percent

compared to last month.

The biggest cause of the decline

is the poor response

to the Moojin serial murders.

The approval rating

of the ruling party has hit the lowest.

The public wants to know whether

the ruling party will stay in power

or the opposition party will take over

with only one year left

until the next presidential election.

You received a package.

Who's the sender?

It doesn't say.

Officer Jung's cerebral edema

has resolved a little bit.

After a discussion with the neurosurgeons,

we decided to try another surgery.

-You can't go in.

-I want to know where my boy is!

-Take her.

-Come with us.

Let go of me!

Please calm down.

Ba-reum is dying, but you're alive?

Die.

Die, you scumbag.

BE HAPPY, BA-REUM

HANG IN THERE, OFFICER JUNG BA-REUM

The surgery was successful.

On top of the brain damage

caused by the compound skull fracture,

there was secondary damage

from increased intracranial pressure.

Depending on his condition,

we will operate on him a few more times.

Thank you.

It is out of our hands now.

Please pray for him, everyone.

What is it?

Did something go wrong during the surgery?

Is Officer Jung in a critical state?

Sung Yo-han has passed away.

The cause of his death

is acute septic shock.

We removed the contaminated parts

as much as we could during the surgery,

but we think he died of shock caused

by the remaining abdominal infection.

He should've told us

where Han-guk is before he died!

Officer Jung Ba-reum,

who went through three major surgeries,

has not regained consciousness

for over ten days,

leaving many in sadness.

Rallies are held around the country

to pray for Officer Jung's recovery,

and charitable activities

are taking place for him.

HANG IN THERE, JUNG BA-REUM

WE HOPE YOU RECOVER SOON

Animals aren't allowed in hospital wards,

but the director made

an exception for Officer Jung.

Ba-reum.

You can hear Eo-beong, right?

Eo-beong's telling you to wake up.

Listen to Eo-beong and wake up, okay?

Detective Ko, I'm fine.

Don't be ridiculous.

Look at yourself.

You look like you're about to faint.

What's the big deal about that?

Because of me, Ba-reum

Ba-reum

Bong-yi.

It's not your fault. So don't feel guilty.

The surgery went well.

He'll wake up soon. Okay?

Take off your shoes and lie down.

-Hello.

-Excuse me.

Forget about everything

and get some sleep.

-Detective Ko.

-What is it?

Thank you.

If it weren't for you,

Ba-reum would've died.

And

thanks for plucking up the courage.

Get some sleep.

THE LATE SUNG YO-HAN

How will I pay for all my sins?

Where's Eo-beong?

-How sad.

-I feel so bad.

-Mom!

-Mom!

Where am I?

Ba-reum.

Ba-reum.

How many fingers am I holding up?

Two.

And how many are these?

Ten.

What is this?

It's a pen.

What is your name?

How old are you?

Who is she?

Why can't he remember anything?

His frontal lobe

and temporal lobe are damaged.

Inside the temporal lobe

is the hippocampus.

He could experience memory loss

if the hippocampus is damaged.

But given that he recognizes most things,

I think it is caused

by a temporary shock from the surgeries.

Brain surgeries are straining

for the body,

so his brain may need time

to get back to normal.

Ba-reum

You really don't remember me?

Not at all?

Who is she?

Don't look at me like I'm a stranger.

You were

You were an incredibly sweet person to me.

I'm tired. I need to get some sleep.

The hospital is crowded

with people gathered around

to congratulate Officer Jung Ba-reum

for being discharged.

He received three brain surgeries

due to the injuries

he suffered

while fighting a serial m*rder*r.

Here he comes.

-Mr. Jung Ba-reum.

-Here he comes.

Thank you.

One moment, please.

Thank you.

Sit over there.

Get some rest.

-I'll go make some porridge.

-Okay.

CERTIFICATE OF APPRECIATION

GOOD CITIZEN AWARD

I guess I was a good person.

Indeed you were.

You were a good kid

who never caused trouble growing up.

Even now, Ba-reum. You're kind and just.

What a relief.

You were 100 days old then.

Where is my mom?

She died in a car accident

when you were a baby.

I see.

How can I not remember anything?

The doctor said

it's because you had big surgeries.

He told us not to worry.

Your memories will come back slowly,

so don't worry too much.

Okay.

Let's move as soon as possible.

We have to move

because of the redevelopment anyway.

I cannot leave you

in this terrible house by yourself.

Just say it was a mistake, okay?

Say that you aimed for his leg.

Just say that Han-guk

reminded you of your nephew.

But I don't have a nephew.

I'm an only child.

My parents tried ten years

before having me.

Just say you have one

-so that you don't get penalized.

-Yes, sir.

Why do you do everything

this troublemaker tells you to do?

You think your dad

will get you off the hook?

Come on in.

I have a nephew

who is around the same age as Han-guk.

That's why I did it. I'm sorry.

Sergeant Ko. Why didn't you

sh**t the suspect's leg first?

You should fire a warning shot

and aim for the lower body.

Don't you know the rules?

If he'd done that while the suspect

was about to as*ault Officer Jung,

Officer Jung Ba-reum

wouldn't be alive today.

Tell us yourself, Sergeant Ko Moo-chi.

It was a mistake, right?

You aimed for his leg, right?

It wasn't a mistake.

I shot to k*ll that b*stard.

So please investigate me for m*rder.

That crazy b*stard.

This is the final decision

on Sergeant Ko Moo-chi.

You used your g*n to save

the victim from an urgent situation,

so we find you not guilty.

What are you talking about?

I k*lled a man.

-Detective Ko.

-I shot to k*ll him.

-Don't you hear me? I shot to k*ll him!

-Detective Ko!

I fired the g*n to k*ll him!

Sergeant Ko. You'll get a one-year

suspension and a six-month pay cut.

Senior Policeman Shin,

two months of pay cut.

-That is all for today.

-Wait a minute.

-Wait.

-Detective Ko.

What are you doing?

Send me to him.

-Send me to where he is!

-Let go.

Put me behind bars!

-Commissioner.

-Are you okay?

He's bleeding.

Oh, no.

We will now begin. Start with anesthesia.

Put your head up.

The anesthetic is going in now.

I'm sorry, baby.

Pictures of the body

of Byeon Sun-yeong, the second victim,

were found in Sung Yo-han's basement.

The police also confirmed

that Sung Yo-han's cell phone

was tracked in places

near the m*rder scenes

at the time of the crime.

Based on Officer Jung's testimony

and circumstantial evidence

that he tried to k*ll Ms. A,

we have now concluded

that Sung Yo-han is the culprit

of the seven serial murders in Moojin.

Ba-reum.

I'm coming.

Hey.

-I'll throw these away.

-Okay.

I'll take this. I'm studying this again.

I'm studying to become

a prison guard again.

-Prison guard?

-Yes.

I made a promise to Chi-guk

that I'd work with him when he wakes up.

Chi-guk?

Chi-guk, you, and I

were like the Three Musketeers.

I see.

Go see if there's anything

to pack in the backyard.

We'll throw those away,

so just leave them out.

-Okay.

-Thank you.

Should I load these too?

Just leave them there.

Then we're done.

Come on out. We should get going.

We don't have the right to indict

because Sung Yo-han is deceased,

so the case will be handed over

to the prosecutors' office.

But even after it is handed over,

we will continue our search

for Kim Han-guk.

Bong-yi, be my bride

when you become an adult.

Kang Deok-su, whose sentence

was reduced to ten years

because he was drunk at the time

of his crime, will be released tomorrow.

The police are preparing thoroughly

in case of any emergencies.

The atmosphere is already tense

near Building A in Moojin,

which is suspected to be his home.

The police officers are on guard,

and the residents

are voicing their concerns

as they're witnessing the sight.

Execute Kang Deok-su!

-Execute him!

-Execute him!

Guarantee the residents' safety!

-Guarantee safety!

-Guarantee safety!

Oh Bong-yi. You're not her.

-Amend the law!

-Amend the law!

Guarantee a safe world!

-Guarantee a safe world!

-Guarantee a safe world!

Execute Kang Deok-su!

Oh Bong-yi.

-Execute him!

-Execute him!

-Excuse me.

-Guarantee a safe world.

-Guarantee a safe world!

-Guarantee a safe world!

I'm glad that she isn't here.

Guarantee a safe world!

-Guarantee a safe world!

-Guarantee a safe world!

-You call yourself a human being?

-You're less than human!

Kang Deok-su.

Officer Ko?

You have a good memory.

Yes, it's me.

The one who put you behind bars.

What are you doing here?

I'm here to warn you.

Do something like that again,

or I'll k*ll you.

I'm sorry.

I will spend the rest of my life

atoning for my sin.

I am on the lookout

to k*ll someone right now.

So mark my words.

I will do my best to be a decent man.

Where are you, Oh Bong-yi?

1 YEAR LATER

The campaign

for the 20th presidential election

will officially begin today.

Lee Gyeong-seon of Gukseondang,

the ruling party

Our Lee Gyeong-seon

-Candidate Number One!

-Candidate Number One, Lee Gyeong-seon

Let me get some sleep!

-Our Lee Gyeong-seon

-Candidate Number One!

-Gukseondang's Lee Gyeong-seon

-It's too early for all the noise!

-Prepared to work for the people

-Candidate Number One!

-Candidate Number One, Lee Gyeong-seon

-Lee Gyeong-seon!

Even if you try to win me over,

I'll vote for the one

who restores the death penalty system.

Sir.

Did you enjoy your year-long break?

-You have been appointed.

-To where?

Goodness.

I'm so proud of myself

for sticking out in this crappy place.

Those petty jerks.

I didn't even do it on purpose.

How could they exile me

to this place for a year

for punching the commissioner?

Once I get back

to the Violent Crimes Team,

I won't have to wear this uniform again.

Goodbye, Pyeongan Police Substation.

I've been placed

in the Pyeongan Police Substation.

I am Officer Jung Ba-reum.

Hey, Officer Jung.

I heard that you'll be my replacement.

-Nice to meet you.

-Likewise.

It's the face

of the Pyeongan Police Substation.

Welcome, Officer Jung.

Come on, Officer Nam. Go bring it.

You know that the entire nation

is rooting for you, right?

Don't overwork yourself.

Think of it as a probation period.

-I will do my best.

-No, take it easy.

Drink this up. It's an herbal tonic.

-Go have a seat.

-Okay.

Put that down and come with me.

There are so many things to teach you.

No. Sit down and rest.

Why? I must train him so I can leave.

We got an order.

He's not himself yet and needs more rest.

He's not recovered?

Then why has he been reinstated?

The election is right around the corner.

You know how the entire nation

prayed for his recovery.

They must show

he's returned to work and is doing well

for the ruling party's approval rating

to go up and for them to stay in power.

I'm sorry to tell you this, but

-What is it?

-He mustn't overwork himself,

so don't make him do anything.

Leave him alone.

Just leave him alone.

If he wants to go home, let him.

If he doesn't come to work,

just let him, okay?

It's unbelievable.

It's like he's the boss here.

Officer Nam will end up

taking on all the work.

I guess that's the perks of having

the entire nation rooting for you.

So are your memories back?

Yes. There are things

I still don't remember,

-but they're mostly back.

-I see.

That's good.

Then you remember Detective Ko, right?

Dong-gu told me a lot about him, but

I don't remember him yet.

Good gosh.

You don't remember Detective Ko?

You're not back to yourself.

-What?

-What?

It's nothing.

I heard you live around here.

That's right.

I live behind that apartment building.

My aunt asked me to live near her place.

Oh, so your aunt lives here too.

By the way,

I wonder if I got back to work too early.

I'd better do well.

I don't want to be a nuisance.

Yes, you are a nuisance.

I'll be leaving soon, but Officer Nam

-One moment, please.

-What is it?

Please pull over.

Who did this?

Why did he have to run

for president and be humiliated?

I'm going to vote for him.

What?

I had so much spare time

while I was recovering,

so I listened to every candidate's speech

and looked up their pledges.

I think he's the sincerest one

and has a clear plan

for the future of Korea.

I respect him.

Thank you.

What are you doing, Detective Shin?

Stay still. I have my reasons.

What are you doing?

-Detective Shin. Over there.

-He's at it again.

-A thief!

-Stay in the car.

My purse! Oh, no.

Come here.

Stop!

Hey, stop!

Officer Jung, you shouldn't run like that!

Stop the motorcycle!

Stop right there!

Shouldn't we catch him?

-Let go of me.

-Stay still.

Help.

Let me go.

What is this feeling?

Don't just stand there.

There's so much work to do.

You see those over there?

Sort them all out and make a list.

You want me to do this all by myself?

There's no one else besides you and me.

We're the only ones on the team?

They made a big fuss in the media

about creating this team.

You know when something happens,

they create something

to calm the public down

and then once it subsides, they scrap it.

I'd rather work

in Transportation or Civil Affairs.

You're here because they didn't want you.

-Who do they think I am?

-A troublemaker and a time b*mb.

In other words, no one wants you.

So stop complaining and get to work.

-Then I quit.

-Don't you have work to do?

What?

The Evidence Team.

Don't you know

the Evidence Team members have g*ns?

-But it's a back office job.

-Says who?

Sorting out evidence

is only a part of our job.

At times, you'll have to go out

and collect the evidence yourself.

A special provision of g*ns.

You may have better chances here.

I have a wife to take care of.

If it weren't for her,

I would've done it myself.

I mean, the thing you plan to do.

There's no wallet or a phone.

It's a homicide by a robber.

No, it isn't.

-What?

-It's just disguised as one.

Who are you to say such nonsense?

How do you know if it's nonsense or not?

What?

-How dare you!

-What?

-How old are you?

-I'm old enough. So what?

Detective Kang! We found tire tracks here.

Go.

From there to here.

You were right. No wonder you have

the entire nation's support.

Look.

There are tire tracks

and traces of the body being dragged.

That means someone drove here

with the body and dragged it there.

What kind of a robber would k*ll a person

and leave the body

and her purse over there?

Don't be ridiculous.

-Come on.

-It makes sense.

Her belongings are gone,

but the k*ller had

the m*rder weapon prepared.

He took the phone and wallet to make it

look like a homicide by a robber.

Right. Seeing how she was k*lled

with her face down,

the victim must've known the k*ller,

and the k*ller must've held a grudge

against the victim.

Identify the victim

and look into people around her.

That's not true.

It wasn't a revenge m*rder.

What's wrong with you?

I'll talk to him. He hurt his head, so

You know, right? He fought Sung Yo-han

and got brain surgery.

Go guard the area

so no one contaminates evidence.

-Come here.

-But Detective Shin

Just go.

HEADHUNTER SERIAL m*rder CASE

This is the Hurricane limited edition

that you begged us to get you.

Your dad stood in line

early in the morning to buy it for you.

Happy birthday, Moo-chi.

If anyone messes with you,

I'll teach them a lesson.

No, let's just camp out here.

Please, Mom?

We're only staying

because it's your birthday, Moo-chi.

Sort these, too.

Han Seo-jun case's been ruled

by the Supreme Court already.

Why do we have the evidence kept here?

The prosecutors' office

were about to discard them,

but I brought them here.

Evidence from the Han Seo-jun case

is still a great reference

for investigations to this day.

Our job isn't

to simply store and sort evidence.

Our main task is to collect and archive

investigation research materials.

You make it sound like

an incredibly important team.

Then send me more men.

I can't do all the work by myself.

No one wants to work here.

Then you should recruit some.

I hope Chi-guk wakes up soon

and recovers like you have.

He will.

Don't ever lose hope.

It's my wedding invitation.

You'll be the host. You know that, right?

I can't host a wedding.

No one else can do it.

Chi-guk is bedridden.

Of course, you have to do it.

It was my first day at work today,

and I could see how tough

it must've been for Chi-guk.

Was it that tough?

There's a gangster's lackey

in my area of responsibility,

and he keeps harassing his cellmate

when he's old enough to be his grandpa.

He was taking it too far,

so I told him to stop.

And now he is harassing me too.

He calls me "Dung-gu."

I've been called other names,

but "Dung-gu"?

He belittles me for being a rookie.

-I just wanted to

-Did you punch him?

-Are you crazy?

-No, I read his palm.

He has the palm lines of a criminal.

You and your jokes.

Be careful. You could get in trouble.

It'd be nice

if Bong-yi came to my wedding too.

Where has she disappeared to?

Bong-yi?

I guess you don't remember her yet.

How was your day?

Tell me how it was to be back at work.

I saw a dead body.

A dead body?

-Did you wet your pants?

-Don't be silly.

It felt rather strange.

-My heart was racing, and

-Your heart was racing?

I guess you were shocked.

You did say your heart was racing

when you saw a dead cat.

It wasn't like that. It was more like

Yes, it was.

You threw up all day that day.

It's probably nothing.

-Over here.

-Hello.

-Good evening.

-Hello.

-Hello.

-Hello. Please have a seat.

Thank you.

I worked on a movie with him.

And this is Lawyer Wu Hyeong-cheol.

He helped me with my scripts.

-You all know Ba-reum, right?

-Of course.

And this is my fiancé, Ms. Kim Seul-gi.

She starred in my short film.

-Congratulations on your wedding.

-Thank you.

-Congratulations.

-Thank you!

Thank you.

-I need to use the restroom.

-Okay.

Be careful.

Dong-gu, it's not too late.

Reconsider marrying Seul-gi.

Cut it out, you punk.

She will never give up

on becoming an actress.

You think she'll settle

with being a civil servant's wife?

She will never.

She'll leave you

if someone gives her a role in a movie.

Will you stop?

-Stop it, you b*stard.

-Calm down.

Stop it.

You may be drunk,

but don't cross the line.

Do you know what they say about her?

They say

she's an opportunist serial flirter.

Everyone in this industry

knows except him.

It's so upsetting.

You're too naive.

You're such a pushover, Dong-gu.

-You jerk.

-Hey.

You run your mouth like that

whenever you drink.

-You jerk.

-Dong-gu.

Let go of me.

Are you okay, Ba-reum?

You jerk!

Let go of me!

Are you okay?

Are you hurt?

It's just a slight scratch. I'm fine.

You scraped your forehead.

By the way, I didn't know you could fight.

You even sucked at Whac-A-Mole.

On today's Sherlock Eung-nyeo,

we will cover the suicide case

of a college student in her 20s.

According to the police,

she was economically distressed

and committed suicide in her room, and

Here's the evidence

from a m*rder in Pyeongan-dong.

Have you eaten?

That jerk.

COMPLETE LIST OF EVIDENCE

These jerks.

You left out two pieces of evidence!

The rope and the weapon aren't here.

Bring them here now.

We're busy.

But you aren't, so come get them yourself.

What?

How dare he hang up on me?

This punk.

Where is he?

This is called the Highwayman's Hitch.

It is the quickest knot

you can make while hiking.

You can fix the rope tightly

without tying it.

Then is this a knife for hiking too?

Yes, it is.

Then we'll have to see if there was

a hiking expert around the victim.

Wait a minute.

This knot is a variation.

This isn't how it's supposed to be tied.

It's quite peculiar.

It may have been purposely modified

from the Highwayman's Hitch,

-or maybe it was a clumsy mistake.

-I see.

So this is not

standard Highwayman's Hitch?

That's right.

What are you doing out there?

Why ask the obvious?

I was told to come myself, so here I am.

You can take them back

after signing this and rewriting the list.

That brat.

What did that officer mean when he said

the culprit wasn't

the victim's acquaintance?

It was nonsense. Don't worry about it.

He isn't in his right mind

because he hurt his head.

Is he the one who hurt his brain

while fighting against a m*rder*r?

Yes.

I guess Officer Jung is back.

Pyeongan Police Substation

It should be around here.

You crazy b*stard!

Officer Jung?

I'm sorry.

This rolled away

while I was throwing out trash.

I scared you, didn't I?

I'm really sorry.

You haven't changed, Officer Jung.

Do you know me?

Right.

Are you trying to get yourself k*lled?

You were nearly k*lled because of a bird.

What is it? Does your head hurt?

Detective Ko Moo-chi.

Detective Ko!

Sir. Oh, my.

-This is all we have.

-Thank you.

How are you doing?

Yes. I've been getting treatment

and have gotten much better.

When one piece of memory

about someone comes back,

other memories of that person

come back too.

I'm grateful you remember me.

I should've remembered you sooner.

How did you know that I was here?

-Did Detective Shin tell you?

-No.

The Violent Crimes guys

were badmouthing you.

-What?

-They said you talked nonsense

about how the k*ller wasn't

the victim's acquaintance.

Right.

Please take a look at this.

Look at this knot.

With a knot like this, the victim

must've been able to move her hands.

And the knot can come untied easily too.

Right. They said

it's the Highway knot or something.

So they were looking for

a hiking expert around the victim.

If he was an expert, why did he use

this knot to tie up the victim

when he knew it could be untied easily?

Take a look here.

You can see that the victim

moved around her wrists a lot.

You're right.

Then why did he tie the rope this way?

-He did it for fun.

-What?

He tied the rope this way for fun.

The victim probably thought she could live

and tried to untie the knot.

The culprit must've watched

her struggle for fun.

If he watched her die for fun,

why did he stab her in the back?

Look at this.

It's not a deep stab wound.

He didn't stab her deep enough to k*ll her

and enjoyed watching

the victim suffer in pain.

Then in the end, he strangled her.

Only a psychopath would do such a thing.

It wasn't his first m*rder.

What?

If it had been his first time,

he would've been too flustered

to clean the crime scene.

But the crime scene was too clean.

There wasn't a single fingerprint

or a strand of hair.

If we don't catch him soon,

he'll k*ll again.

How are you so sure?

I can

I can just feel it.

You can feel it?

Why?

It seems like you've changed a little.

You seem different from before.

Do I?

The victim probably thought she could live

and tried to untie the knot.

He did it for fun.

He tied the rope this way for fun.

Mr. Bok is questioning the suspect.

The pub owner testified that you'd been

hitting on Kang Min-ju for a month.

That's him?

This is the tire track

we found at the crime scene.

And this is the tire of your car.

I've never been there.

There are millions of cars

with the same tires.

I think you have the wrong guy.

There's no way he's a psychopath.

These are the things

we found at your place.

I didn't k*ll her!

I don't think it's him.

Why are you so sure

that the culprit is a psychopath?

-Don't be ridiculous.

-Just tell me

where you were at the time of the m*rder!

You see

National Forensic Service called.

The semen found in the victim's body

is a match with his DNA.

See? You're the one who got it wrong.

He can feel it?

I listened to a man

with a brain injury like an idiot.

Gosh, I'm unbelievable.

KFDC2019.

The police arrested Mr. B,

who stalked Victim A, a pub waitress,

as the prime suspect of her m*rder.

He claims that it was consensual sex

-It's not him.

-and is denying the charge.

Here's evidence from Nojin-dong m*rder.

Hey, stop there.

You

You didn't leave out

any piece of evidence again, did you?

I'm asking you a question.

No, I didn't.

Stay right there until I confirm it.

What's with the injury on the wrist?

-Isn't there a rope or anything?

-No.

-There isn't?

-No.

Wait! That brat.

I don't see it.

Did an army officer hung the clothes

or something? Why are they so neat?

The clothes aren't even washed.

If we don't catch him soon

He'll k*ll again.

Officer Jung was right.

When Hong Na-ri was found,

her front tooth was cracked,

and her forehead was bleeding.

Based on the blood

on the shattered mirror,

the k*ller probably smashed

the victim's face with it,

which cut her forehead

and cracked her tooth.

The door lock is intact.

There are no signs

of her trying to escape.

She must've known the k*ller.

Damn it.

Why is there no water?

What's strange is that the MO

is different from Kang Min-ju's m*rder.

Kang Min-ju was kidnapped, m*rder*d,

and abandoned in different places.

But Hong Na-ri was found at her home.

The body wasn't moved.

And he didn't leave the m*rder weapon.

It's different from the Kang Min-ju case.

And Hong Na-ri was lying

on her side, not facing down.

Well

Right.

Was it done by someone else?

No, it was the same person.

How are you so sure?

The mirror.

The k*ller smashed her face

with the mirror on purpose.

On purpose?

To watch her die in pain in more detail.

He tried to watch the victim die

in more detail using the mirror?

In order to watch the victim

die in pain in more detail

Right here.

This is where he k*lled her.

Then the victim's husband came

and did CPR on her.

CPR?

Yes. There were signs of CPR on her body,

so her husband was arrested.

They weren't on good terms

and were separated.

That's enough motive for m*rder.

No, the CPR must've been done

by the k*ller too.

What?

So what you're saying is

that the k*ller's a psychopath

who kills for fun.

Then why did he try to save her?

Did he change his mind?

He didn't change his mind.

He wanted to bring her back

to k*ll her again.

He wanted to enjoy watching her

die in pain as long as he could.

His MO is getting worse.

It's more violent than the last time.

I think he's experimenting

to find a fun way to k*ll people.

If we don't catch him soon,

countless more people might get k*lled.

How can you be so sure of that?

It's just

I thought about what I would do

if I were the k*ller,

and this is what I would do.

He was afraid

that the police would catch wind of him

if this knot was discovered,

so he used the clothesline to k*ll her.

Then he probably put it back

after he k*lled her.

And I'm sure the clothes were hung

in the neatest possible way.

Right. How did you know that?

I just know.

And I am sure

the k*ller is a perfectionist.

Officer Jung.

Let's catch him together.

What? You'll catch him?

-We must hand this over to Violent Crimes.

-No, things are different now.

According to you,

he already k*lled two people.

But you said he could've k*lled

more people in the past.

That means there could be more victims.

That means he is

a psychopathic serial m*rder*r.

Right.

You see

I have to catch someone

who deserves to die with my own hands.

I failed the last time,

but I will succeed this time.

You'll help me, right?

Thank you for the offer,

but I have things to do

at Pyeongan Substation, and

No, you don't have to handle

the substation's work.

-What?

-I heard from Detective Shin.

You don't have to do anything

at the substation.

What do you mean by that?

-You don't have to go to work. Come on.

-What do you mean?

What did I eat?

My bottom's so sore.

I'm sure

the k*ller was acquainted

with the victims.

But the victims didn't have

any mutual acquaintances.

What am I missing here?

He did it for fun.

He tied it loose on purpose.

I've seen this before.

Headhunter

Eleven Ga.

EVIDENCE FROM PARK HYEON-SU CASE

THE HEADHUNTER'S 21ST VICTIM

Detective Park's wife kept saying

she must find her baby.

You see

He is a mutated monster

who should never have been born.

That comment instigated it.

He broke into Detective Park's house

and kidnapped Hyeon-su and Hyeon-suk.

Hyeon-suk was found

30 km away from his house

early in the morning the next day.

He was hit by a car.

He must've run out into the road

while running away.

Search the area thoroughly.

Even soldiers were brought in

to find Hyeon-su, but she was never found.

And about five years after that,

they started constructing

Guryeong Mountain Tunnel.

They found clothes and shoes

that Hyeon-su was wearing

when she was kidnapped.

They tested the DNA

using the hair found on the hair tie,

and it was a match.

He still hasn't accepted

that Hyeon-su is dead.

That's why he keeps digging up the ground

to find Hyeon-su's body.

EVIDENCE FROM PARK HYEON-SU CASE

HEADHUNTER'S 21ST VICTIM

The MO is different

from Kang Min-ju's m*rder.

She was kidnapped, m*rder*d,

and abandoned in different places.

But Hong Na-ri was found at her home.

BODY FOUND TIED WITH A ROPE

POLICE BEGINS INVESTIGATION

Hello, Detective Shin.

About the victim

of the pub waitress m*rder

May I see the knot

that was tied around her hands?

The Evidence Team?

Right, this is a variation

of the Highwayman's Hitch.

It does seem like

they were tied by the same person.

But this one seems clumsier than this one.

It's like a child tied it.

Hello?

Excuse me.

EVIDENCE STORAGE

YEAR 2020, YEAR 2021

How did Han Seo-jun know about this knot?

Surgeons usually make knots

when they operate,

but this is a knot that hikers use.

Han Seo-jun probably learned it

from someone.

-The one who taught Han Seo-jun

-Yes.

Or Han Seo-jun could've taught it

to someone else.

Someone who learned from him.

That person would be the prime suspect.

Let's talk to Han Seo-jun first.

What is it?

Someone must've been here.

What?

This wasn't placed like this

when I came in.

-What are you talking about?

-It's different.

You think you're a genius

that can remember the angle of every box?

Hurry up. We must get there on time.

-Hurry up.

-It's different, though.

-Han Seo-jun refuses to see you.

-What?

He doesn't want to see

the one who k*lled his son.

But

You wanted to see me?

It's you.

I heard you nearly died because of Yo-han.

I wanted to apologize on behalf of my son.

We've met before, right?

Me?

I'm disappointed

that you don't remember me.

I guess the surgery wasn't so successful.

What a shame.

But your eyes seem to have changed

after the surgery.

Do they?

Don't let him intimidate you.

You remember this, right?

It's the knot you tied on Park Hyeon-su,

Detective Park Du-seok's daughter.

This is similar to the knot

that hikers use in rescues.

-Who did you learn it from?

-I never learned it from anyone.

Is that so?

So you're saying

that you came up with this yourself.

Did you teach it to anyone?

I've never taught it.

Then has anyone seen you tie it?

No.

Try rummaging through your memory.

This is very important.

I've never tied it,

learned it, or taught it.

I told you.

Don't lie.

If you didn't teach it to anyone,

how is it possible that someone

made the same knot

you made when you k*lled

a child 26 years ago?

Why are you asking me that?

I had no expectations for you anyway.

I will not accept the fake apology

that you made on behalf of your son.

I said it's not a lie,

but you don't believe me.

You don't understand

what I'm trying to say?

It's not him.

He didn't k*ll the child 26 years ago.

Right.

Say hello to my friend before you go.

Say hi.

This is my cellmate.

What is this memory?

MOUSE

A witness?

It wasn't in the investigation record.

Or Han Seo-jun is the k*ller,

but someone else tied the knot.

An accomplice?

Did the brain surgery make you a genius?

Do you know Producer Choi Hong-ju?

Was I in love with her?

That child

I was wondering if you know

where she is now.

You look well.

It's nice to see you, Officer Jung.

Why does my heart suddenly ache?

-Officer Jung.

-Yes?

Do you want to join our team?

Me?
