THIS IS A WORK OF FICTION.

CHILD ACTORS AND ANIMALS WERE FILMED IN ACCORDANCE WITH SAFETY GUIDELINES.

Damn punk.

Take that, asshole.

"Stop bullying the weak"?

Trample him.

You damn punk! What do you think you're doing?

Damn asshole!

Hey, the cop is here.

- The cop! - Damn punks…

Why didn't you fight back?

You know taekwondo, boxing, and judo. Did you just learn all that for show?

I don't do it to learn how to hit people.

But still, a man should be able to throw a punch before he dies!

And what if they die?

Detective Choi.

I promise I'm really fine now.

I'm living my life, so…

Enjoy.

So eat this,

and stop coming to see me from now on.

You know, Detective Choi doesn't mix jjajangmyeon just for anyone.

Even if you snitch on something big, there's only a chance I might.

Cha Su-yeol.

You should become a cop.

Let's see.

Since five people have died…

you can save five people.

You should become a police officer.

Even better if you save more.

Why did he ask for this?

Can you make that brighter?

Brighter?

A SECOND MURDER CASE IN WOONGSAN

Zoom in here.

What the?

- The image is flipped. - Yeah.

I guess it was a printing mistake.

Hold on.

HSART

What the?

Then, the head was actually on the left side,

and not the right.

It seems like the newspaper print was flipped.

He did not reference this newspaper clipping.

He must have seen court or investigative records.

Hey.

Can you search for court and investigative records on Jeong I-shin?

You already are?

Okay.

Let's get out of here.

COURT

Pardon me. I'm with the police.

Is Dr. Choi Mi-gyeong available?

She's currently overseas for a conference.

Then,

by chance, could I get Dr. Choi's number?

As per Jeong I-shin's request, it was a closed trial.

The judge, the prosecutor, defense attorney, and the doctor

who conducted the psych evaluation were the only ones privy to the court records.

And the prosecution claims that there have been no reported data leaks.

The psychiatrist is supposed to return to the country in a week.

She says the only picture she ever saw was in the paper.

The judge died three years ago.

The defense attorney isn't 100% sure after 23 years,

but he's never knowingly shared court records.

I asked if he still had them.

He said he'd check and let me know.

Okay. Good job, everyone.

He may be from Narcotics, but he's pretty good.

It's way too soon to be talking like that.

Hello, Mr. Kim. Were you able to locate the file?

I'm sure it used to be here.

That's the only file missing.

Does anyone else have access to this office besides you?

There's the office cleaner, and I sometimes have guests wait here

if I have a meeting that runs late.

It wouldn't have been too difficult if someone was determined.

Is there anyone you suspect from those who had access?

Just all acquaintances.

It can be something minor.

Has anyone unexpectedly tried to cozy up to you?

Someone unexpected…

When I was building my house, I had to deal with all this paperwork.

Someone called about a missing document,

so I went to the district office.

Then, what happened?

It was their clerical mistake.

The rep there was so apologetic.

We ended up chatting a bit.

I think it's been 30 years already?

The other lawyers at this office and I sponsor a nearby orphanage.

And it turned out that rep grew up in that orphanage.

Did you recognize him?

We only ever visited once a year.

And with the large number of kids,

it's hard to remember every face.

I guess he remembered mine.

He said he hesitated, unsure whether to let on that he recognized me.

Maybe he was here

about a year ago?

Just a moment.

Here it is.

Here.

Seo Gu-wan, Department of Safety Construction,

Anam District Office.

Did he also wait in this office?

Yes, he showed up unannounced.

I asked him to wait here until my meeting concluded.

Why did he come to mind now?

There was never a boy by that name at the orphanage.

I found out later when I ran into its director.

That did make me feel a bit uneasy,

but he didn't seem like a bad guy, just a bit awkward.

It's not like I was harmed in any way.

But are you saying he might have taken the court records?

We'll do the afternoon walk in an hour.

Go!

After asking around, we found out

Seo Gu-wan is currently living alone.

He goes to and from work on his motorcycle.

He should be home soon.

Okay. Stay alert at the entrance, and out of sight.

Yes, sir!

This is a nice car.

We confirmed he's an employee at the Anam District Office.

I just sent over what I found.

CIVIL SERVICE CANDIDATE REGISTRATION FORM:

SOCIAL WELFARE MAJOR

PARENTS: UNKNOWN

It's not the orphanage that the lawyer mentioned,

but he did grow up in one.

There was a grain of truth in all the lies.

They said this is usually when he comes home.

Hyuk, any updates?

None to report.

When is this punk coming home?

Everyone, listen carefully.

Make sure he doesn't catch on,

and we don't make any movements until we confirm he's inside his place.

That was all unnecessary, wasn't it?

Not at all.

That is the stage we're at.

Checking off boxes and feeling out each other's rhythm.

I'm glad you see it like that.

I'm sure everyone was surprised.

I just dropped out of the sky one day and became your squad leader.

They're a dependable bunch.

Just remember we're on the same team.

Okay.

Sir, he's home!

Seo Gu-wan! Hey!

Stop! You punk!

- He got away. - Damn it.

Sung-gyu, he's headed toward the main road.

I see the motorcycle. Blocking the road now.

Damn it.

Stop right there!

Get him!

- Damn punk. - Stop!

Hey!

Stop, you punk!

Where are you, Hyuk?

Seo Gu-wan!

Watch out!

Hyuk!

Are you trying to get yourself killed?

You almost killed him, Mister!

Hyuk, can you stand up? Are you okay?

Damn it.

He's collected all sorts of personal data.

RESIDENT REGISTRATION CARD, RESIDENT REGISTRATION RECORD

Seriously?

That's quite an impressive password you got there.

Found it. Jeong I-shin's court records.

NAMBU DISTRICT COURT RECORD OF TRIAL

He has the lawyer's records.

And even the Anwon Prison guard's records.

RESIDENT REGISTRATION RECORD

Captain.

CHA SU-YEOL LEE JUNG-YEON

This bastard.

Bae's, Hyuk's, and even mine.

This bastard managed to dig up all our personal information.

He couldn't change the lightbulb?

This crazy bastard.

Detective Kim.

Captain.

This son of a bitch is devoted and diligent.

It's like welcome to Mantis World.

Excuse me.

I think he's sick.

I'll go and check out the pharmacy that's listed.

- Get yourself a bandage for that too. - Okay.

I'm going to take this back to the office,

- and take it apart. - Okay. See you.

What's this? Why is it all wrapped up?

It looks like a safe.

It's a 3D printer.

Captain.

This is…

Kids, Daddy's home.

I picked up some fried chicken.

You're sleeping already? You couldn't wait up for me?

So mean.

You make me sad.

Then I'm going to finish it all by myself!

DEAR MR. SEO GU-WAN

From Jeong I-shin, Anwon Prison.

Jeong I-shin sent him letters from Anwon Prison?

What?

How did those two exchange letters?

While the whole world thinks Jeong I-shin is dead…

What's this bastard's deal?

What are you talking about? I don't understand at all.

I'm back.

That woman

is not helping us.

She's using us.

Seo Gu-wan was instructed to kill

by Jeong I-shin.

What?

It's late. How rude of you to show up unannounced.

Why did you do it?

How could you egg on blood-crazed Seo Gu-wan?

Were five killings not enough to sate you?

Answer me!

You wrote those letters.

You told him he could kill people,

and be just like you!

You told him it was no big deal.

Not once have I written that nobody a letter.

Then, what are these?

Do you have proof I actually wrote these?

And you call yourself a police officer?

Are you saying you did not write them?

Turn the lights off on your way out.

In prison,

your bedtime, mealtime, and wake-up time are always the same.

When the lights go off, you have to sleep.

You have to follow that schedule if you want to eat and see the sun.

You know that, right?

So, anything that happens in the world outside of our scheduled time,

you all take care of it.

That's the order of things.

Does it look like I'm here for a picnic?

This is a jail cell.

Come in the morning if you want to have a discussion.

Aren't you a police officer?

Honey, you're not hungry?

The police have decided to reveal the face of Seo Gu-wan,

a prime suspect in the recent murders,

and announced they will carry out a public investigation.

Seo has a history of being treated for schizophrenia and delusional disorder,

and is noted to have displayed mental instability recently.

Authorities warn that Seo may be in possession of a firearm

and poses an immediate threat to public safety.

The police noted his height to be…

INCORRECT PASSWORD

This is the handwritten confession Jeong I-shin wrote

23 years ago.

What you see on the right is a letter Seo claims to have received from her.

The handwriting seems--

It's not just the handwriting.

There is not a single typo in Jeong's confession.

Her sentences are concise.

Comparatively, the letter Seo Gu-wan received

contains a large number of typos.

It was clearly written by someone else.

Then, who wrote him those letters?

Please take a look at Seo's handwriting

in the blueprint for his homemade gun and his notes.

Seo Gu-wan wrote them himself.

DEAR MR. SEO GU-WAN

Based on the evidence we gathered at his home,

he worshipped Jeong I-shin as if she were some sort of saint.

There is a chance

Seo wanted to commit a murder but lacked the courage to follow through,

so he looked to Jeong for support

or some sort of command.

I believe he inflicted those delusions on himself.

It's possible, considering his history of schizophrenia, a disorder

known for delusions and hallucinations.

I went to his pharmacy,

and I was able to obtain his prescription.

From there, I looked into his doctor.

He set up an appointment last month

but never showed up.

A bit over a month ago would be around the time

of the first murder at Nodu Stream.

His symptoms must have worsened if he stopped taking his meds.

So, he's out of his mind, making him even more unpredictable.

Any reports come in?

They're all baseless or pranks.

UNLOCKED

Hey.

I unlocked Seo Gu-wan's computer.

Who is that Mister? Where's Daddy?

Listen to me.

You must do whatever that man tells you to do.

You must.

Who are these people?

He's definitely a nutcase.

What the?

Watch.

This bastard…

There's a license plate.

We have a license plate.

Find out who it's registered under and their address.

Have backup ready so we can move out once the address is confirmed.

And gear up.

- Right, he could be armed. - We got it.

Let's go.

Hello, this is Bae Sung-gyu from Major Crimes Team One.

I repeat.

The police have decided to reveal the face of Seo Gu-wan,

a prime suspect in the recent murders,

and announced they will carry out a public investigation. Seo has a history…

I'm done.

Mommy.

You're okay. Don't be afraid.

I did as you asked.

Where's my husband?

I hear the water running.

Why do you have the water running in the bathroom?

Rip it.

Rip that up.

Mommy.

You're okay.

If we just do as that man says, we'll all be okay.

Right?

I mean, Daddy. Sorry.

He's Daddy.

If you just do as Daddy says, we'll all be okay.

Rip it.

Do as Daddy says. Go on.

Where's our daddy?

Where is he?

You're not our daddy, mister!

No. Stop that.

I can rip it.

He's just too little to understand. Just let me do it.

Seung-min, you…

Please just let me rip it.

Quiet.

What's wrong?

There's someone else here, isn't there?

It's just us.

So-won!

Honey!

Why are you lying to me?

See? They're chatting away right now.

You don't hear that?

I don't hear anything.

What chatter?

I mean…

Then, are you saying I'm crazy or something?

Why can't you hear that?

- You're a jerkface! - That's no way to speak to your dad.

This Mister is a jerkface.

Seung-min…

I need to teach you a lesson.

- Seung-min! - Mommy!

Seung-min. Please, no.

Seung-min!

- Seung-min! Please let him go! - Mommy!

- This is a shared home for neighbors. - Seung-min!

- Please avoid causing noise disturbances. - Mommy, save me!

- …Be mindful of neighbors when walking. - Save me, Mommy!

Please, I beg you.

I'll do whatever you say.

Please let him go.

No! Daddy!

Freeze. I'm with the police.

Roger that.

I'm with the police.

Let him down slowly.

I told you someone else was here!

Shut up and let him down! Slowly.

He peed his pants.

I just wanted to give him a bath.

Let him down.

Seo Gu-wan.

You're under arrest for the suspected murder of Kim Hyeon-u and Kang Su-cheol…

You're Seung-min, right?

Just hang in there. I'll have you free in no time.

…the right to remain silent.

Anything you say can and will be used against you.

And I'll be teaching you a mighty lesson at the police agency.

They're both safe.

Hyuk, check the bedroom.

Yes, ma'am.

- Mommy! - Come here, my baby!

My babies!

Captain.

Mr. Kim Tae-seok isn't here.

Hello there.

Is that it?

- Sir! - At ease. Take care now.

- Thank you for the food. - Dig in.

NODU STREAM VICTIM KIM HYEON-U

Kim Tae-seok, the missing husband, and Seo Gu-wan are half-siblings.

Half-siblings? So, different fathers?

Yes, that's right. Seo's birth mother

gave up her parental rights before he was even born.

So, after he was born, he was sent to the orphanage.

And his birth mother remarried a few months later.

And a year afterward, she gave birth to Kim Tae-seok.

Ms. Kim Yeong-seon, his birth mother, died of a chronic illness a year ago.

It was his birth mother who abandoned him. Why go after the half-brother?

Reverse Life.

What is that?

We checked Seo's Internet history,

and it showed he read this web novel, Reverse Life, over a dozen times.

It falls under what's commonly called the RTR genre.

"RTR"?

Regression, Transmigration, Reincarnation.

Stories about lives that change overnight.

Something like,

a pauper wakes up to discover he has become a prince overnight.

But Seo doesn't really fit the profile for the Nodu Stream and Warehouse murders.

For now, just focus on Kim Tae-seok.

Do whatever you have to do to make Seo talk.

Kim Tae-seok can't end up on that wall.

- Got that? - Yes, sir.

Mr. Kim Tae-seok. Her husband.

Where is he right now?

Is he still alive?

Mr. Seo,

behaving like this could end up hurting you later.

Mr. Seo. Look at me when I'm talking to you.

Mr. Seo.

Your mom abandoned you.

A mother, wife, and cute kids.

A happy family.

All of that could've been yours, no?

It was meant to be mine.

It's not "could've." It was always meant to be mine.

So did you just want to steal it from him? Just like in Reverse Life?

Steal? Come on.

It was always mine.

I was "abandoned"?

You must be talking about your son.

"Waiving custody rights" is just a nice way of putting it.

Listen, if I were "abandoned" at the orphanage,

then you "abandoned" your child with that pathetic husband of yours.

- How do you-- - You did, didn't you?

He was just an autistic pain in the ass for you.

You asshole!

- Were you ashamed of him? - Go.

Of course, you wanted to abandon him. It would've been even better if he died.

Shut the hell up!

- Detective Kim! - Let go of me!

You're just playing into his hands.

Kim.

Hey.

Mr. Seo, what are you trying to do here?

Let's take a seat first. Sit.

Okay.

But… are you sure…

we're alone here?

We are.

Lies.

Just turn all this off and leave us.

See that?

I've never seen

Detective Kim worked up like that before in my life.

I knew you looked us up and all,

but I didn't expect you to even know such details about Detective Kim's past.

That's nothing.

There are all sorts of documents at the district office.

And I filled in the missing pieces by myself.

Why go after Kim Tae-seok?

If that jerk had never been born,

my mom would've come back for me.

I'm sure of it.

Sure.

So, did you…

take a swing at Kim Tae-seok

and kill him?

The Mantis…

What was your mom like? What sort of person was she?

Don't worry. I won't tell anyone.

I know she wouldn't want that.

If I tell you,

will you tell me where Kim Tae-seok is?

Damn it. Don't they know this is important?

Let's keep it down over there.

Just ignore them, Mr. Seo.

You know about Jeong I-shin's life in prison, right?

With espresso. The prison guard told me.

That happened

because she negotiated with us.

I'm proposing you do the same.

Let's keep it a give-and-take, one by one.

I wouldn't make this proposal if you weren't on the Mantis's level.

So,

tell me what you think about your mom.

She's a criminal.

Gosh.

If he were 15 kilos,

he must have been about this big?

What?

That's how much the kid weighed.

I heard he was ten.

His ankles were worn raw with the bones showing.

He was chained up.

One of his nostrils was caved in.

When the kid's breathing got on his nerves,

he seared the kid with a hot spoon.

What are you talking about?

That boy's father was a beast masquerading as a man.

She killed that bastard.

The Queen Mantis did.

And you just call her a criminal?

Fine. Let's just put it all on the table.

You've killed someone before, right?

Or at least attempted to?

You damn brat!

Come on. That's why you became a cop, right?

Those eyes…

You're her son, all right.

Such incredible insight.

I never thought of it that way.

As expected, you're quite astute.

I feel like we're on the same wavelength here.

Just throw me a bone here.

Where is Kim Tae-seok…

No,

can you just tell me if he's alive or not?

What now?

"Same wavelength"?

We're on totally different ones.

I shouldn't have missed that.

Maybe I messed up?

It's pointless.

We have no other choice. Let's take him.

He's a Mantis fanatic.

He will talk in front of her.

What?

Must we keep relying on Jeong I-shin like this?

Passing off what she told me as my own discovery

to the team feels wrong.

Not to mention, watching her

throw us some scraps and shrug us off is just…

Damn it.

Su-yeol.

Back then…

There's something I didn't tell you about what happened 23 years ago.

Here.

Good job today.

You don't need to give her that.

It's fine.

Go on, say thank you.

Thank you.

You're welcome.

Let's go. Say goodbye now.

Goodbye.

It's so obvious you love kids.

No plans?

Raising you is already a full-time job. Latte?

No. Black coffee for me.

Do you really have no plans to have kids?

I can just ask Su-yeol.

Don't. He doesn't like talking about that stuff.

I see… Cha Su-yeol is to blame.

Don't people who grow up without parents often try to make up for that loneliness

with big families of their own?

Yeah. I'm like that.

Sorry.

I swear I didn't mean it like that.

It's fine. I feel the same way too.

Those thoughts grow stronger around the anniversary of my parents' deaths.

I do want to have kids.

But Su-yeol's memories about his parents are…

Not good?

He doesn't talk about it,

but he sometimes calls for his mom in his sleep.

That tough detective looks for his mommy in his sleep?

What a cutie pie.

If she were alive, I could at least try to reconcile them.

What? Don't be ridiculous.

Not having in-laws is the biggest perk in the world.

Must you put it like that?

Hey.

Oh, that's right. You said black coffee.

Hello. It's nice to meet you.

He's currently a suspect in an ongoing investigation.

I'm not sure bringing him here was the right call.

Just in case.

So, we finally meet.

Where are we?

It doesn't look like a prison.

I heard you imitated me.

As close as humanly possible.

Why did you do it?

The world needs to know.

Everything the Mantis did for them.

They need to know how you dealt with the scum of the earth.

They do.

All of it.

I mean it.

Is that so?

How did it feel?

Well… It was nice.

I felt euphoria.

It was just as you told me. It was nothing.

But why did you use an ax?

Didn't it end too quickly?

That was because…

Well…

The blood must have splattered on your face.

Did it?

How did it feel?

Well…

It was…

How long did life cling to him after he was decapitated?

About 20 seconds?

Was it 30 seconds?

Well…

Tell me.

You got to indulge because of me. The least you can do is share.

You're lying.

You…

never killed anyone.

No, I did.

You made a gun for no reason, didn't you? Because you were afraid.

I…

You had no bullets.

I knew it.

As if a nobody like you could imitate me.

Get lost.

No, I did kill.

Kim Tae-seok, that prick…

He's dead.

Probably.

"Probably dead"?

What?

Did you just toss him into the river or something?

With your eyes closed?

Because you were afraid to finish him yourself?

No, that's not true.

Really?

Where'd you do it? How'd you do it?

Tell me.

How did you do it?

I fixed it. Restored everything to its place.

Of course, you can't tell me. Because you didn't kill him.

No gall to be found.

And you were afraid.

Yes. That's who you are.

Afraid of everything.

That's why your mother abandoned you.

She knew early on that you would grow up to be this pathetic loser.

Screw you!

Bitch.

These jerks…

Look at these jerks go.

Why?

Oh, because of that cop son of yours?

Then, what about me?

After I've come all this way, following in your footsteps!

Oh, because we're not related by blood?

Is that why you're acting like a complete bitch?

I see.

I will announce it to the whole world.

Serial Killer Jeong I-shin is alive!

And her son is Cha Su-yeol, an active-duty police officer!

Oh, and Lee Jung-yeon too!

I will even tell the world about that prick's wife!

Damn it.

Jeong I-shin!

Stop it!

- Let go of him! - I-shin!

Stop! Let go of him!

Hey! Wake up!

Seo Gu-wan! Wake up!

- Have you lost your mind? - No.

Dr. Park.

We need to end it.

We need to kill him now.

You heard him. He knows everything.

Wake up.

Seo Gu-wan! Are you okay?

- Hey! - Stop it, you punk!

- Seo Gu-wan. - Seo Gu-wan!

The gates are locked.

Seo Gu-wan!

Don't come any closer, you pigs!

You need to calm down and set the gun down.

- Shut up. - Seo Gu-wan.

This will only make things harder for you.

Who are you? Come out here.

Come out now!

Come out, you pricks!

Hold on. Just wait.

It's so noisy.

All of it.

Yeah. Seo Gu-wan.

You're right. It's noisy.

You're not the only one who can hear it. I can hear it too.

Seo Gu-wan.

I know.

Lies.

Commissioner,

I'd like to thank you from the bottom of my heart

for saving me and my kids yesterday.

But I still don't know where my husband is right now.

I'm worried something might've happened.

I haven't heard anything about my husband yet.

Please find him.

Please, I beg you, Commissioner.

Please save him!

- Please… - Oh, no!

MANTIS

Hello?

Okay. Understood.

Kim Tae-seok's wife is at the gates of the agency. It sounds like a mess.

They said to stay inside and keep out of the chaos.

We didn't do anything wrong.

Where are you going?

We need to make Seo Gu-wan talk.

Seo Gu-wan isn't here.

- What? - What?

Section Chief Choi and Captain Cha took him somewhere.

Did you not hear?

Damn it.

AMBULANCE

Sir. Can you hear us?

You need to stay with us.

What's his name?

It's Seo Gu-wan.

Mr. Seo Gu-wan.

Mr. Seo, you need to stay with us.

- Where are you? - Right behind you.

How's Seo Gu-wan doing?

He's in bad shape, but conscious.

You saw how he was with Jeong I-shin.

He is not the copycat killer.

The issue is Kim Tae-seok.

We need to get Seo to talk quickly.

As long as Kim is safe, there will be no casualties.

The media will forget about Seo Gu-wan soon enough.

What if he doesn't talk?

We have to make him.

What if he speaks nonsense?

What if it's nothing about Kim and…

Mr. Seo. Can you hear us?

What if he wants to talk about me and that woman?

Don't worry. I spoke to the hospital director.

Jeong I-shin was also treated there during her prison sentence.

Seo Gu-wan will be kept completely hidden from the world.

Right now, Kim Tae-seok is--

Detective Kim is calling.

Just bend the truth.

Blood pressure is 90 over 50.

Pulse is at 124…

Pardon?

Yes, understood.

What did he say?

He said Seo tried to kill himself in his cell.

They're transporting him to the hospital.

What?

Is he hurt badly?

What a pain in the ass he is.

Mr. Seo, we're almost there.

We need to end it.

You heard him. He knows everything.

Lee Jung-yeon too!

I will even tell the world about that prick's wife!

We need to kill him now.

- Mr. Seo. - Mr. Seo!

What's wrong with him?

- What's wrong? - It's cardiac arrest.

Can you give me a hand? One, two,

- …three, four, five. - Mr. Seo.

Seo Gu-wan!

No, you can't. Seo Gu-wan!

How's he doing?

Luckily, the bullet only grazed him,

but his skull was fractured, so there was some bleeding.

They treated it.

He's alive, but he needs strict bed rest.

He's in a room by himself with a hospital security guard.

Security will be tight. Don't worry.

Seo Gu-wan…

When Jeong I-shin asked him about what he did with Kim Tae-seok,

he didn't say he was killed or dead.

He said, "probably dead."

Do you remember how uncertain he sounded?

No, I did kill.

Kim Tae-seok, that prick…

He's dead.

Probably.

What?

Did you just toss him into the river or something?

Sir.

He couldn't refute her.

If he had really killed Kim,

he would've spoken up.

What if Seo Gu-wan left Kim Tae-seok

in a place where he would inevitably die

without outside intervention?

What if Seo just abandoned him there?

Then, there's a chance that Kim could be alive somewhere.

That means we still have time.

The only one who knows where that would be is in there, in that condition.

I fixed it.

Restored everything to its place.

What? What is it?

I think…

Su-yeol, what is it?

Hey, Ji-an.

What is this?

YEONAM MEDICAL CENTER

He took a picture of the same hospital every year since 2007.

Seo believes Kim Tae-seok stole his life.

He believes their lives have been switched.

And…

Before Seo tried to take his own life, he told us,

Kim was "probably dead." Not, "I killed him."

He said everything was restored to its place.

If Seo didn't do the killing himself,

but locked Kim up somewhere until he died,

it would be somewhere Seo believed was the origin of his despair.

The hospital where he was abandoned. Don't you think?

Just look at these photos.

For years, he obsessively took photos of this one place.

That must mean this place is meaningful to him.

What do the rest of you think?

Two days after someone goes missing,

their survival rate goes down to 30%.

We don't have time to waste.

Please believe in me and follow my lead.

I haven't led you astray yet.

"Believe"? This is an investigation, not a church service.

Is conviction enough in a narcotics investigation?

Stop. That's enough.

Let's head out first.

We should check if there's any doubt.

And Captain Cha's theory isn't outlandish.

All right. Let's do whatever we can. Head out.

After you arrive, check in often.

You heard him.

Yeonam Medical Center at Hongshin Intersection. Move it.

He must have imitated Jeong I-shin's murder.

The third murder was a drowning. Assuming he attempted that,

we need to look for places with water.

Let's go.

AQUATIC PHYSICAL THERAPY ROOM

I'm from the Nambu Police Agency.

The basement is clear.

SHOWER ROOM

- Laundry room is clear. - Did you find anything?

He's not here.

What now? Should I check the sink too?

Let's go.

We're on a wild goose chase.

Let's just grill Seo Gu-wan until he talks.

He is in a coma after a suicide attempt.

But isn't continuing to investigate this place

when there's nothing to find also a waste?

Ji-an, did you find anything?

Nothing yet.

I combed through all the footage for the past few days.

Seo Gu-wan is nowhere to be found.

He has to be here.

No, I did kill.

Kim Tae-seok, that prick…

He's dead.

Probably.

He couldn't see it through.

He must have abandoned him in a life-threatening situation.

INTERNAL MEDICINE, SURGERY, OB-GYN

FLOOR GUIDE

Pardon me.

Is this on its way to the ward laundry room?

That place is too small for all this.

There's a laundry plant.

That's not listed on the floor guide.

Why would they if no one ever wants to go there?

Where is it?

- I'm downloading it now. - Good job.

Well? Let's just go back without him.

We can't just go by ourselves. What about Captain Cha?

Laundry plant.

What?

Sung-gyu, you go that way.

Captain!

Mr. Kim Tae-seok!

Sung-gyu!

Sung-gyu, call for a doctor.

You can't die.

Kim Tae-seok!

You can't die.

You can't die.

Please.

You can't!

So many damn mirrors. It's like 4DX in here.

It must be a message for us.

"Stop going after the wrong guy and making a fool of yourself."

I just saw you on the news.

Tell me you didn't see your mom again.

Lee Jung-yeon. Does she know about me as well?

And this "zero" section.

There's just a number with nothing else.

That number can't be meaningless.

The "first" murder we do not know about.

How would Seo Gu-wan know about that?

There's another beyond the original five, isn't there?

Jeong I-shin!
