A BRAIN ON TRIAL

Kid.

You should go too.

Stop right there!

Hey!

Damn it.

Kid.

Something similar has
definitely happened before.

Is this the police?

ONE DAY EARLIER
THE DAY OF THE JO NA-YEONG INCIDENT

Fire!

Fire!

-Fire!
-Fire!

-What's going on?
-Fire!

Fire!

Who...

It is indeed a dead body.

It's a m*rder case.

YI-NA'S MOM

She's not picking up.

I think she was on her way home.

I should go.

I'll go to the station
and trace the location.

Okay.

Hey.

Myeong-sae, my heart hurts.

I'm still terrified.

-Go to the hospital.
-Come with me.

I'm going to check the scene first.

Please take her to the hospital.

You go ahead, okay?

Hello, officers.

I'm Detective Geum
of the Neuroscientific Investigation Team.

Oh, the team that's been in the news?

I'm glad you're here.

I have a feeling
your team might have to take this case.

Sorry?

Hello.

I'm Detective Geum
of the Neuroscientific Investigation Team.

I DID WHAT MY BRAIN TOLD ME TO DO

I was on my way home.

The streets were oddly deserted today.

So I was walking along,

enjoying the fall breeze.

A shoe?

What?

At first, I thought it was a doll.

But then,

I got a weird feeling,
so I took a closer look.

It's a real person!

I was so startled

that I collapsed.

You were the first person I called.

Did you run into anyone in the street?

No.

I mean, I don't know.

I was in such shock.

I might just not remember.

Okay.

Get some rest for now.

What kind of nutjob would leave a body
in the middle of the street

when there are
cameras everywhere nowadays?

You don't have security cameras?

And you don't have a dashcam either?

How can you not have a dashcam
in such an expensive car?

Listen.

What I want is to see the footage
from the security cameras in the street.

To access footage of a public space,

we need the cooperation
of the property manager

due to the Personal Information
Protection Act.

If we file a formal request
to the district office,

it'll take some time.

Please take care of it
as quickly as possible.

The case has been entered into our system,
so please give it some time.

We'll be in touch.

Bye.

I'm so tired.

-Let me ask you a favor.
-My gosh!

Goodness. Don't creep up on me like that.

Do you have a lot to hide?
Why do you get startled so easily?

Forget it.

You think like a psychopath.

This psychopath has a favor to ask.

No, don't. I won't do it.

A break-in?

But nothing's missing?

And he lunged at you out of the blue?

He definitely has a grudge against you.

A grudge?

I'm sure you can't pin one down,

because there are too many candidates.

You're good at speaking the truth
in such an annoying way.

You're good at giving compliments
in such a threatening way.

Both of you, enough with your nonsense.

Did you report it?

Yes.

They said they'd look into it and call me,
but I don't trust them.

So you want us to
give that station a little nudge?

Okay.

A close friend of mine works there.
I'll look into it for you.

Oh, do you want us to give you
a smartwatch just in case?

The one with an emergency button
you can press to call the police.

Why don't you wear one instead?

Come on,
I only suggested it out of concern.

Save your concern for
your sudden bowel movements

so you're not looking for a restroom
while out in the field.

How gracious of you
to express concern for my health.

I'm so grateful.

Hey.

I see everyone's here.

Let's start the meeting.

Name, Jo Na-yeong. Age, 27.

She's a makeup artist.

She was k*lled in the studio
where she lived alone

and was dumped on the street.

The cause of death
was asphyxia due to neck compression.

A security camera inside the building

caught the suspect entering her apartment.

He used a smoke b*mb
designed to exterminate c*ck.

He made it look like a fire had broken out

and lunged when the victim
opened her door.

Then the next day...

the suspect was caught on camera
leaving with Jo Na-yeong's dead body.

One unusual thing
is that the victim's phone disappeared

after it was turned off at the scene.

It appears that the suspect took it.

After going through
her social media posts,

we found photos of her phone
and determined its model.

Keep an eye on it
to see if it turns back on.

What about her call log?

We've filed a request
to the service provider.

Anything on the suspect?

We haven't been
able to identify a suspect.

It was her day off,
so she was home all day.

She had a boyfriend
but didn't see him that day.

Hold on. Something's off here.

Why did we get a case
that has nothing to do with the brain?

A strange message was found at the scene.

-Pull it up.
-Yes, sir.

I DID WHAT MY BRAIN TOLD ME TO DO

This was definitely done to target
the Neuroscientific Investigation Team.

It's a direct challenge to our team.

Don't you think so, Dr. Brain?

I do.

You're right. It's a challenge.

You never let me down, Dr. Brain.

So I strongly insisted
that we take on this case,

and that's how it was transferred to us.

I'm getting a bad feeling about this.

We're not thrilled
to work on this case either.

But the suspect was clearly caught
on the security camera,

and there were witnesses too.

So it's only a matter of time
before we catch him.

Don't you worry.

You didn't see this person?

But he was standing right out front
when you ran out of your apartment.

I'm not sure.

I didn't see him.

I didn't see anyone.

Maybe he hid behind the smoke.

But...

How could they not have seen him?
He must have stood out.

The four people who were in the corridor
at the time didn't see him.

It doesn't make sense.
Could they all be in on it?

No, it's entirely plausible.

My lab conducted an experiment
related to this phenomenon.

We showed this video to the participants

and told them to count the number
of passes made by the people in red.

Once the participants
finished watching the video,

we asked them
if they saw a person wearing a mask.

More than half of them said they didn't,

even though you can clearly see
a conspicuous person in a mask right here.

No way. How did they not notice this?

You see,

when the brain is
preoccupied with something,

it can miss even significant changes
happening right before our eyes.

This is called "change blindness."

It's also the secret behind magic tricks.

So when they saw all the smoke,

they were so distracted by it

that they didn't notice
the guy in the helmet.

That could very well be what happened.

I thought we'd catch this guy easily.

This is turning out to be a headache.

I guess it's time
to overwork my eyes again.

SEOBU POLICE STATION

You should take a break.

We need to catch this jerk
as soon as possible.

We'd catch him in no time
if we could just track him down.

I'm getting cramps.

Let me give you a shoulder massage.

No. It's okay.

I have a sports massage license.

Stay still.

Here.

Gosh, be gentle.

Captain, please be gentle.

My goodness!

What's going on, you two?

Are you close enough
to give each other massages?

No, this isn't...

That's right.

Is there a problem?

No, not at all. There are no problems.

Well, get back to it then.

I should indeed get back to this.

I'll help you as well.

Captain, it's getting really late.

You should go home.

Working late has paid off.

I got him.
He stopped by a convenience store.

What?

Yes, it's him.

Where is this?

Yes, that's him.

He came in here.

I got nervous
when I saw he had a helmet on his head.

What did he buy?

Packing tape.

How did he pay for it?

He paid with cash.

Do you remember anything unusual?

Yes, I do.

That would be 1,000 won.

He looked suspicious,
so I took a closer look.

He was wearing some kind of uniform
inside his jacket.

I think he might be a cop.

A cop?

The part-time employee said
she saw some kind of badge on his chest.

He's likely to be a cop.

Now that you say that, the pants
look like they're part of a uniform too.

Did the victim personally know a cop?

Yes, she did. Her boyfriend.

Im Yeong-hun. Age, 29.

He's in Mobile Force 2
at the Seoul Metropolitan Police Agency.

IM YEONG-HUN

It was my day off, so I stayed home.

It was Ms. Jo's day off too.

You've been dating for a month.

It's odd that
you didn't meet on your day off.

Na-yeong said she was tired.

There is a record of our phone call.

The cell tower data should trace you
to the tower near my home.

Are you sure it wasn't because you fought?

I saw you were indicted...

GANGSU POLICE STATION

...for assaulting your ex-girlfriend.

I sued her back
for making a false accusation.

The case is on trial now.

Did Ms. Jo know about this?

No.

Perhaps she found out that day.

No.

Perhaps Ms. Jo found out that
you'd been sued by your ex-girlfriend,

and you lost your cool

when she refused to meet.

That's not true.

Are you interested in the brain?

Pardon? What do you mean?

The brain. This right here.

No.

Why do you ask?

What's your take on this guy, Dr. Brain?

The fact that he didn't register
the word "brain" right away

tells me he isn't interested in it.

"I did what my brain told me to do."

I don't see him
as someone who'd write that.

I still find it really suspicious

that he keeps telling us to
check the cell tower data for his alibi.

What about the call history?

It does support his statement.

The victim's last call
was with Im Yeong-hun,

and the cell tower data
placed him near his home.

He seemed way too calm
for someone who's just lost a girlfriend.

Not to mention
the as*ault charge from his ex-girlfriend.

Nothing went missing,
so we can rule out robbery.

She wasn't sexually assaulted either.

m*rder following a bad breakup
seems most likely.

I agree with all of you.

DETECTIVE KANG

Hey, Detective Kang.

Yes.

Did you find out
who broke into Dr. Shin's house?

Okay, got it.

Send it to me. Thanks.

Hold on a second.

What's going on here?

How is this possible?

The same person?

The person who broke into my house

is also the suspect in the m*rder case?

I got an odd feeling from his stance,

so I had Gangnam Police Station

obtain security footage of your intruder.

Just like you said,

he took off on a motorbike from the park.

The helmet he wore then

is the same one that our helmet guy wore.

Did he change his clothes?

That jacket he's wearing
was released last year,

and it's reversible.

To sum it up,

the helmet guy
who disposed of Ms. Jo's body

turned his jacket inside out,
got on a motorbike,

changed into a cap
after coming to a park in my neighborhood,

and came to my house?

That's right.

Could it be the victim's boyfriend,
Im Yeong-hun?

They seem to have similar figures,

but I can't be sure.

Have you met Mr. Im before?

Not that I remember.

In any case, this was a direct challenge
to the Neuroscientific Investigation Team.

He broke into your house

and left a message saying
that he did as his brain told him.

I think this person
is challenging Dr. Shin.

I don't know who he's challenging,

but there's definitely
something unusual happening.









Dr. Hwang, you have a visitor.

Hello, sir.

What brings you here all of a sudden?

I doubt you came because you missed me.

I have something to ask you.

Did you

meet Ha-ru?

What makes you think that?

Please,

answer my question.

No, I didn't meet him.

Are you telling the truth?

Whether you believe me or not

is up to you.

Excuse me.

Has Dr. Shin Ha-ru...

You mean the neuroscientist?

You know him?

Of course.

He's been here too.

Who was he here to visit?

He's been visiting Dr. Hwang regularly.

Darn it.

The man who broke into Dr. Brain's house
is the man who k*lled Ms. Jo?

This is giving me a headache.

What on earth is happening?

Dr. Brain,

what's on your mind?

I'm trying to think of a way

to get the culprit
to turn on Ms. Jo's phone.

Hey, that's a good idea.

What is it? Do you already have an idea?

I don't.

Jeez, you got my hopes up.

What's wrong with you?

Jo Na-yeong's phone has been turned on.

JANGWON CORRECTIONAL FACILITY

That's the cell tower that
Ms. Jo's phone pinged

when it was turned back on.

The GPS analysis shows
that her phone was turned on...

at Jangwon Correctional Facility.

Jangwon Correctional Facility?

I'm associated with an inmate there.

I should go and check.

-Go and arrest the guy.
-Yes, sir!

They must be flustered by now.

They're probably curious as to
why the phone was suddenly turned back on.

How does it feel

to mess with their heads?

Oh, my.

You don't seem to be feeling good.

Well,

to think that I'll soon be arrested...

What's wrong? Are you scared?

No.

It's just that I'll miss this.

I felt a thrill
for the first time in my life.

I'm disappointed to think
it'll be over soon.

Don't worry too much.

It's your first offense
and you have an illness.

You'll be back out soon enough.

Are you sure?

One thing at a time.

Just do as I say.

Okay.

What's happening?

What is it?

The punk's on the run.

JANGWON CORRECTIONAL FACILITY

That feels good.

Why is my back feeling so itchy?

It's k*lling me.

Yes?

Can I help you?

I'm here to meet Dr. Shin Ha-ru.

I see.

Are you one of his fans?

They come by sometimes.

Yes, I'm a fan.

I see.

That's too bad. He's not in right now.

Excuse me for a second.

It's the guy Dr. Shin is with.

Hey. Are you at the correctional facility?

The punk has already fled.

Location tracking shows he's there,

at our police station.

Our police station? What are you on about?

Anyway, it looks like he's there,
so keep your eyes peeled.

Oh, and the uniform
the convenience store clerk said

the culprit was wearing.

It's not a police uniform.

I think it's a prison guard uniform.

A prison guard?

I guess that's possible

since civilians can't tell

a police uniform
and a prison guard uniform apart.

Yes.

Okay.

I see.

Got it.

Get back soon.

I love you.

SUBSECTION CHIEF KIM

What?

Why did he say "I love you"?

He said that out of the blue.

People act out of character...

-They're about to die.
-if they're about to die.

Oh dear.

I suddenly want to see my kids again.

Why am I tearing up?

It's because you're scared.

I heard it all.

You know I'm the culprit.

Freeze.

I'll smack you if you move.

Are you and Dr. Shin close?

Yes. We're close.

We're best friends.

I guess you'll have to die then.

What?

I want to cause Dr. Shin some pain

before going to prison.

You got it wrong! We're not close at all.

We've never even eaten together.

Even if I were to die,
that jerk wouldn't bat an eyelash.

Let's find out.

I said he wouldn't care!

He wouldn't!

How dare you attack my subsection chief!

Darn it.

You're under arrest
for the m*rder of Jo Na-yeong.

You have the right to remain silent.

What you say can and will be used
against you in a court of law.

Got that, you punk?

Damn it!

Captain,

thank you.

You saved my life.

If you know that,

please treat me better from now on.

Yes. You bet I will.

I'm so touched.

You called me "my subsection chief."

Sir!

Damn it.

He completely played us.

He had us in the palm of his hand.

I'm positive he's challenging Dr. Brain.

He said he wanted to teach you pain
before going to prison.

Do you know him?

I think we met when I visited the prison,
but I don't remember him.

Why is he doing this
to someone he barely knows?

He might be under the control
of someone who knows me.

We checked Ms. Jo's messages.

It seemed that the two of you

had already broken up a year ago.

I told you we didn't break up.

We had agreed to take a break.

That's why I kept my ring on

and resisted the urge to call her.

She betrayed me and dated some other guy.

That's not betrayal.

That's called a breakup.

You said you wanted to teach me pain.

Why?

Because you seem like a perfect guy

who has everything.

You really are a piece of work.

Why did you break into my house?

I just wanted to look around.

Oh, right.

Because I'm a fan.

You said to me,

"Kid. You should go too."

What did you mean by that?

I meant you should go
and join your parents.

Why did you call me "kid"?

Because you look like a kid to me.

Did Dr. Hwang Dong-woo put you up to this?

No.

It's what my brain told me to do.

What is

your brain like?

You'll find out soon enough.

Do you think that prisoner,
Hwang Dong-woo, made him do it?

It's very likely,

given that he and I recently discussed
my parents' car accident.

What's odd

is how he knows about my memory
of someone saying, "Kid."

Either it's a coincidence

or he's the culprit.

Didn't you say it was just a car accident?

Can you look into my parents' accident?

How long ago did it happen?

It was 28 years ago.

The files are probably gone.

We even destroy files for big cases
after ten years.

Files on car accidents
are never kept for that long.

The k*ller is a prison guard

stationed in a special ward

that houses first-degree
death row inmates.

This incident has sparked concern

as a possible sign of
the prison guards' strained mental health.

The correctional facility
has not yet released an official statement

regarding this matter.

The culprit was revealed to be
the victim's ex-boyfriend...

He's been visiting Dr. Hwang regularly.

It is Dr. Shin Ha-ru.

KOREA NATIONAL UNIVERSITY HOSPITAL

They met?

The prison guard confirmed it.

I should've looked into it sooner.

It's my own fault

for believing Professor Hwang,
that evil man.

Why did he lie?

Probably because he thought
I wouldn't let him see Ha-ru.

Why was he so determined to meet Ha-ru?

I told you
he's always been a destructive man.

But why is Ha-ru
the target of his destructiveness?

He has no reason for these things!

Look at the prison guard!

He got played by that creep
and had his whole life ruined.

What is Ha-ru up to these days?

All I did was tell him

to prove his love.

Then he went
and got himself into such trouble.

Why did you send him to my place?

Did he say I sent him?

I did not.

I guess he's a fan of yours.

A fan would never barge in
with a knife in his hand.

Do you know something

about my parents' car accident?

Tell me.

I thought you said

you didn't want to dig it back up.

Forget it.

I don't want to
tire out my brain for nothing.

If you want to know,
just let me know anytime.

Algernon.

My parents' accident...

Could there be something about it
that I don't know?

Are you asleep?

How can you sleep when I have
so much on my mind right now?

You brat. You aren't even interested.

I should just ask
the person who knows best

about what happened that day.

I told you I'd come to you.

Don't worry about it.

It's been a while since I've come by,

and I had something
I wanted to talk to you about.

I heard you met Professor Hwang Dong-woo.

How did you know?

I know him. He said he'd met you.

I hear he makes you visit him
in exchange for donating his brain.

Yes.

Well, I don't mind meeting with him.

But he kept insinuating

that he knew something I don't remember
about my parents' accident.

Did my parents

not die in an ordinary car accident?

Ha-ru,

that man...

is the devil.

If you spend too much time with him,

you'll become a m*rder*r
or take your own life.

Look at the guard
who k*lled his girlfriend.

I heard he was
in charge of Professor Hwang.

I agree he was probably
controlled by Dr. Hwang.

It's not just probable. He definitely was!

You can't let him get to you too.

I'm not such an easy target.

He's already gotten to you.
You've become curious about him.

It was just...

an ordinary car accident.

That man is plotting
to use your incomplete memory

to shake you up.

But why would he do that?

He was

an advisor to your father and me.

I saw he was a professor of neurosurgery
at Korea National University Hospital

and thought that might have been the case.

He didn't get along with your dad.

He's doing this
because he knows you're his son.

Just because

I'm my dad's son?

He doesn't have reasons for what he does.

He just enjoys destruction in itself.

I'm telling you.

Don't fall for his tricks, okay?

Okay.

Let me ask you one thing.

Is there anything you're hiding from me?

No.

I told you everything I know.

Liar.

-Take care.
-You too.

He's clearly lying.

Why is he lying?

Dr. Shin Ha-ru.

What brings you here,
Prosecutor Han Yeon-hui?

I'm here to see you on official business.

Yes, well, he tried to k*ll me.

Please get him locked up for a long time.

He broke into my home.
That will be added to his charges, right?

Yes.

m*rder, attempted m*rder,
and breaking and entering.

We want to request the death penalty,

but the defense attorney
is making an absurd claim,

so I came here for your advice.

They've submitted
a brain scan of the defendant as evidence.

They're saying his brain
exhibits psychopathic tendencies,

that having a psychopathic brain
constitutes a disability or an illness,

and that he thus
deserves a reduced sentence.

Having a brain
with psychopathic tendencies

constitute an illness?

Medical and scientific experts
do generally agree

that it's a disorder
heavily influenced by biological factors.

Of course, this is still heavily debated.

It seems they plan to insist
that it's an illness requiring treatment

so that his sentence will be reduced.

I bet this was the plan from the get-go.

That's why he left the message,

"I did what my brain told me to do."

Who's the attorney
that's making such an absurd claim?

Cha and Jeong Law Firm
is representing the defendant.

What? That law firm is very expensive.

Is Kang In-h*'s family well off?

According to his statement,
he grew up in poverty.

That's strange.

How did he hire such
an expensive law firm?

Psychopathy is a cause for
a heavier sentence, not a commutation.

Why is that high-profile law firm
making such an absurd claim?

But there's a neurosurgeon
who supports this claim.

Who is it?

The defense counsel
is bringing him in as a witness.

His name is Hwang Dong-woo.

Have you heard of him?

He's a neurosurgeon
who m*rder*d his patients years ago.

Yes, I know him very well.

When did you say he'll appear in court?

Of course.

The air is fresher here than in prison.

Let us go.

As you can see, in Kang In-h*'s brain,

the ventromedial prefrontal cortex

and the gray matter volume
in his superior frontal gyrus

are only 15% of that
of the average person.

His amygdala is also reduced in size,

and there is a reduced connection

between the prefrontal cortex,
the amygdala, and the hippocampus.

This is the typical brain of a psychopath.

This finding provides strong evidence

that Kang In-h* has a brain dysfunction
with a biological basis.

Anyone can tell that he has an illness.

But unlike with other illnesses,

having a brain
with psychopathic tendencies

has not been treated
as grounds for a reduced sentence,

which violates standards of fairness.

Even domestic experts agree

that psychopathy occurs
from a dysfunction in the brain

such as in the frontal cortex.

Your Honor,
the defense is distorting the truth

by citing an ambiguous group
of "domestic experts."

Of course.
That is why I've brought a witness

to provide medical expertise.

I call to the stand Dr. Hwang Dong-woo,

a former neurosurgeon
at the Korea National University Hospital.

He doesn't seem well.

It's all for show.

I bet he's healthier than you.

The witness will take the oath.

I swear

by my conscience

that I shall give the truth,
the whole truth,

and nothing but the truth.

Should there be any falsehood,

I will accept the charges of perjury.

Witness

Hwang Dong-woo.

The defense may ask questions.

Thank you.

Dr. Hwang,
please state your current status.

WITNESS

After being charged
with seven counts of m*rder

and being sentenced to death,

I have been serving my sentence
at Jangwon Correctional Facility.

You were once renowned
as the best neurosurgeon in Korea.

You were a respected doctor

and rumored to have amassed great wealth.

Why did someone like you,
who had both fame and fortune,

suddenly become a m*rder*r?

Because...

I am a patient

with a psychopathic brain.

-What?
-A psychopathic brain?

-Unbelievable.
-So he's a psychopath?

-Is he serious?
-I can't believe it.

How can he be an expert witness then?

Do you agree

that psychopathy is a brain dysfunction,
such as of the frontal cortex?

In other words,

do you agree that psychopathy
is a kind of mental disorder?

I do.

And I

am proof of it.

Then since Kang In-h*
suffers from the same disorder as you,

do you believe
that he possesses the free will

not to commit m*rder
when facing a stressful situation?

We have an affliction.

We don't have the free will

to stop ourselves from committing murders.

That is all, Your Honor.

Order in the court.

The prosecution may begin
the cross-examination.

Yes, Your Honor.

Dr. Hwang,

you are claiming
that psychopathy is a mental illness.

Mental illness makes a person
unaware of their actions.

In a nutshell, their judgment is impaired.

That's right.

But psychopaths
are well aware of their actions.

They are aware of what will happen
when they commit a crime.

That is the difference

between psychopathy
and standard mental illnesses.

You're wrong.

"Aware of what will happen"?

Look at how I've been tied up
and had my life taken away.

Not being able to foresee this

is the same as having impaired judgment.

I guess.

He's not wrong.

I guess he has a point.

Let's say that you are right
and that psychopathy is a mental illness.

If that's the case,

does a cure for psychopathy
currently exist?

There is no way

to fundamentally cure
the brain of an adult psychopath.

Yes, that's exactly my point.

Curing psychopathy
is notoriously difficult.

Since psychopaths
cannot be cured or reformed,

for the safety of our society,

psychopaths should be isolated
from society for as long as possible.

Psychopathy isn't grounds
for a reduced sentence.

It is grounds for a heavier sentence.

Your Honor,

may I finish presenting my opinion?

Go ahead.

Thank you.

Currently, there is no way
to cure an adult psychopath.

However, many attempts are being made.

And the most representative one

happens to be

by the man sitting over there.

It's Dr. Shin Ha-ru's

Psychopathic Brain Rebuilding Project.

Why don't we ask Dr. Shin

whether or not it is possible
to cure a psychopathic brain?

Your Honor,

I call Dr. Shin Ha-ru to the stand
as our witness.

I will allow it.

We'll take a short recess.

I'm getting a bad feeling about this.

I think it's better
that you don't take the stand.

Detective Geum's right.

By the looks of it,
he's trying to provoke you.

Let him do it.

Okay, found it.

The weapon I need
to destroy Hwang Dong-woo's false claims.

Dr. Shin, please take the witness stand.

WITNESS

Dr. Shin, please briefly describe

your Psychopathic Brain
Rebuilding Project.

The project seeks a way

to cure a psychopathic brain
through surgical and medical means.

Can the research be applied today?

No, it's still in the research stage.

I see.

You have received a large amount
of government funding for this project.

Is that not because there's a chance

that psychopathy is curable?

That's right.

Do you believe that
psychopathy is a kind of illness?

Yes.

I think it's an illness.

In that case, do you agree
with the defense that Kang In-h*,

who has the brain of a psychopath,

has an illness

and should be given a reduced sentence?

No.

Dr. Shin,

you just said
you believed psychopathy is an illness.

Yes.

But not everyone who has an illness

becomes a m*rder*r.

Many people with psychopathic brains
manage to live ordinary lives,

and some even enjoy success
and high social status.

Of course, I have heard that
many CEOs have psychopathic traits.

I have even heard
similar rumors about Steve Jobs.

But have you seen
any of their brain scans yourself?

No.

Then doesn't it amount
to mere speculation made by the public?

No.

I have proof.

You have proof?

Can we see it now?

Yes.

Please pull up the functional MRI scan
I have of a psychopath's brain.

What you see on the monitor

are brain scans that capture

reactions to photos
of a gruesome crime scene.

You can see the psychopathic brain
looks different from the standard brain.

The amygdala shows almost no activity,

and it has a severely reduced connection
to the prefrontal lobe.

The amygdala itself is smaller too.

Even smaller than
that of the defendant Kang In-h*.

Based on these photos alone,

this person has
far more severe psychopathic tendencies.

But the brain in this photo

belongs to someone you know well.

Do you want to know whose brain this is?

-Yes.
-Yes!

What's he up to now?

What is this, an award ceremony?

Why is he creating suspense?

The owner of this brain,

the person with
this psychopathic brain is...

It is...

It is...

It's me.

Are you asking about the probability
that I'll commit m*rder?

He's not the murderous kind of psychopath
you're imagining.

I'm confident.

Confident that I can control my brain.

Let's see if that's the case.

There's only one thing I want.

To not break up.

I beg of you.

Please let me have Myeong-sae.

You must really want to see me.

This is beyond disrespectful.

You.

What did you do?
