EPISODE 16
BRAIN WORKS

The number you have dialed is unavailable.

Why won't Detective Geum pick up?

Dr. Brain isn't answering either.

It's been a while since they left.

How strange.

Do you think something happened?

What is this?

What do you think you're doing?

All right.

We will now

begin a game.

An empathy game.

A game to turn Dr. Shin into a m*rder*r.

POWER OFF

The number you have dialed is turned off.

His phone's been turned off.

Something must've happened.

Let's trace their location.

Okay.

Dr. Shin.

You recognize this equipment, don't you?

What is it, Dr. Brain?

Don't keep it to yourself. What is it?

It's a neural coupling.

It measures how closely
the activity patterns of two brains align

when they see or hear the same stimulus.

For example,

if you see a crying child

and you both feel compassion...

your brains will sync to the same pattern.

I have no idea what you're saying.

Sounds like fun.

I'm not afraid at all!

Let me put it simply.

If you empathize with each other,

your brain waves
will show the same pattern,

and you two will win.

"Empathize"?

With Dr. Brain?

That's right. Empathize.

If you empathize with each other

and the brain waves align by over 80%...

those handcuffs will become unlocked.

And what if we can't empathize?

Then the brain waves will not align,

and you'll become murderers.

We won't die ourselves,

but become murderers?

What?

Do we get to k*ll you?

The people you'll end up k*lling...

are right here.

-Auntie!
-Yi-na!

Mo-ran!

SUJEONG BATHHOUSE

How did you end up here?

I got a text from Yi-na's dad

and went to a house in Pyeongchang-dong.

Then I suddenly passed out.

When I woke up, I was here with Yi-na.

Me too.

You too?

That's the house
Ha-ru lived in as a child.

I'm here because a man named
Hwang Dong-woo asked to meet me there.

I think this is his doing.

Hwang Dong-woo?

-Who is he?
-He's...

I'll tell you later.

Yi-na!

Mo-ran!

-Yi-na!
-Stop it.

They aren't here. They can't hear you.

You must be wondering
why I'm keeping them there.

I'll show you why.

Excuse me, over here!

Please let us go.

Excuse me? Hello?

You...

Who are you?

What are you doing?

What are you doing?

Turn off the water valve now!

Let them go right now, you *******!

I'll turn off the water valve

if you two win the game.

But if you lose,
I'll keep the water running.

You psychopath!

You see, I'm not the only one.

There's another person here...

with the brain of a psychopath.

Because of his psychopathic brain,

Dr. Shin lacks the capacity for empathy.

Therefore, he cannot win this game.

Ultimately,

they'll all drown to death.

Shut it!

This won't go according to your plan.

My brain is not like yours.

Wait.

Look, I'll do whatever you say.

So please,

let them go, okay?

No. Let me die instead.

You can take my life, so just let them go!

This man's brain
is completely different from yours.

Given how different you are,

you won't ever be able to win the game.

Shut your mouth

and just get started.

Dr. Brain.

Fine.

Let us begin the game then.

-Mom.
-Yes.

It's okay. I'm here with you.

Yes, Yi-na. Don't be scared.

We'll get out of here.

-Right, ma'am?
-Yes, that's right.

All right.

I'll play a video on this screen.

The emotions you feel
in response to the video

will be displayed here
as brain wave patterns.

Then, the sync ratio
between your brain waves

will be displayed as a graph.

If they are more than 80% aligned,

your handcuffs will be unlocked.

All right.

Let's now begin the empathy game.

It's a mismatch.

You two lost.

Yi-na, are you all right?

Gosh, sorry.

If only we had a shard or something.

Could you look?

Yi-na, you too.

I don't see anything.

There's nothing.

All right then.

Here's the next video.

It's a mismatch.

What?

How is that making you feel?

Well...

I'm not sure how
it's supposed to make me feel.

At least flinch. Did it not startle you?

Not really.

Why would I flinch?

How could you not flinch at that?

It's because of his psychopathic brain.

All right.

Next.

Help.

Please save us.

It's a mismatch.

Please don't k*ll us, mister!

-Yi-na!
-Help us!

If you want me dead, just k*ll me!

Don't resort to such dirty tricks.

What do you mean, "dirty tricks"?

You pretend to be just like other humans,

but your brain shows that you aren't.

That's what I'm trying to prove.

If you think I'm wrong,

try to empathize with the man next to you.

All right, next.

-Step aside.
-Ms. Jeong, why did you k*ll your husband?

The guitarist case?

Jeong In-yeong?

Jeong In-yeong?

I've traced their phones.

They were turned off in Pyeongchang-dong.

In Pyeongchang-dong?
That's where they were headed.

Something's definitely happened.

I need to go there myself.

-I'll go with you.
-Okay.

A mere 27%.

The two of you worked on the same case

but felt such different emotions.

You two are too different.

You'll never win this game.

Shut your mouth,

and show us the next image.

Sure.

All right, next.

Help us, mister!

Please spare us!

Look, sir.

This is considered attempted m*rder.

If you just let us go now...

My husband is a cop.

If you get caught,
you'll be in big trouble.

Do you understand?

Are you laughing, you lunatic?

Dr. Brain, what on earth are you feeling?

What about you?

What are you feeling?

Now, now. Don't fight.

Catch another look at their faces
while you can.

With their deaths, I'll successfully prove

that Dr. Shin's brain
is wired differently from yours.

It was turned off
within a 1 km radius from here.

There are so many buildings here.
How will we find them?

How about we ask the detective
who was in charge of that case?

We may be able to find
details or other clues about the house.

You're right. Yes.

Let's see.

Hey, Detective Yun.

Remember the house where
the doctor and his wife were m*rder*d?

Right, that house in Pyeongchang-dong.

Do you remember its location?

SUJEONG BATHHOUSE

You don't remember?

Come on. Try to remember.

How close was it to the subway station?
Or was there maybe a tree nearby?

What? A window?

An arched window?

It's a mismatch!

Please help us.

Help!

Help us!

Yi-na.

Let's try to get on our feet.

We can't when we're
tied up together like this.

Let's just give it a try.

All right.

On the count of three,

we'll stand up.

One, two, three.

Help...

Mom!

Help!

Mom, are you all right?

Mom!

Mom?

Mom!

Are you all right?

Auntie.

Take a good look at them.

You're responsible for their deaths.

He's wrong, Dr. Brain.

It's not your fault.

This is all his doing.

I gave you a chance.

The issue lies with your brain, Dr. Shin.

The brain of a m*rder*r
that's incapable of empathy.

Free will?

Metacognition?

It's all nonsense.

We humans can act superior all we want,

but we are nothing but pathetic entities

who live under the control of our brains.

Here you are proving that.

Someone's here.

In here! Help!

Help!

Help!

No one seems to be home.

But there's the arched window.

And the house seems old enough.

The trees are trimmed,
so the house must be inhabited.

Could the owner have stepped out?

Help!

Help!

Quit shouting and answer my question.

How did that photo make you feel?

What?

I felt pity, of course.

-Compassion?
-That's right.

Although that one word
doesn't fully capture it.

Why do you ask?

I noticed what
all those photos have in common.

What they have in common?

Right, they all showed people
who looked terrified.

That's right.

He knows that my brain
can't easily pick up on fear

and chose those photos on purpose.

Since I now know how they made you feel,

I'll consciously think
of those same emotions.

Then our brain waves
will be somewhat in sync.

I'll be tricking my own brain.

Really?

No one seems to be home.

It's not like we can jump over the fence.

This is frustrating.

The houses here look similar to me.

-We'll keep searching.
-Sure.

We can beat the test
if he shows us a similar photo again.

I hope so.

Your colleagues were here, but they left.

-Help us.
-Help.

Help.

That's enough.

Get on with the game.

You must be getting desperate.

Fine.

Next.

Compassion.

Compassion.

Hey, kid.

Hey, kid.

Hey, kid.

Hey, kid.

Hey, kid.

-Compassion.
-Hey, kid.

Compassion.

Seriously?

He made me relive a traumatic memory

to stop me from feeling compassion.

Darn it.

About that house we were at.

I think I saw the curtains move
even though no one was home.

I think I should go check again.

Okay, I'll check other places.

-Call me if anything happens.
-I will.

An arched window.

Oh, there's one.

Detective Geum!

Dr. Shin!

No!

-Captain.
-Captain?

-Captain.
-Captain.

Captain!

Captain.

-Captain.
-Captain.

-Captain.
-Captain.

Captain.

Captain.

Sujeong Bathhouse.

Remember the house where
the doctor and his wife were m*rder*d?

The house in Pyeongchang-dong.
Do you remember its location?

Try to remember.

You darn *******!

It looks like
this will be the final problem.

I'll let you say your final goodbyes.

Auntie.

Ha-ru? What's going on?

What are you doing?

Dad. Come save me!

-Dad.
-Save us!

Wait, Yi-na.

I'll come for you, okay?

Hang in there!

Dad. Get here soon.

Be quick.

Okay, I'll be there.

Don't give up, Yi-na!

Yi-na...

Darn you, you psycho *******!

There.

You got to say your goodbyes.

Now, it's time for the final problem.

I really didn't want to say this,

but it looks like I'll have to.

I'm sorry...

for having a brain like mine.

It's not your fault.

No matter what happens,

it's not your fault, so don't be sorry.

This is all that psycho's fault!

Now,

here's the last problem.

Dr. Brain,

pretend that dying man is your friend.

My friend?

My friend...

Algernon.

My only friend is my lab mouse.

How could a mouse be your only friend?

If you don't have a friend,

try pretending that it's me.

How would you feel if I died?

Dr. Shin

wouldn't bat an eyelash

even if you died right in front of him.

He has the brain of a m*rder*r, after all.

Don't you dare compare him to you.

Dr. Brain is different
from trash like you.

He's developed an affection for humans

that the likes of you
could never understand.

Try k*lling me.

k*ll me and you'll find out!

That's a great idea.

Let's do that.

Dr. Brain...

You poor man.

How did you end up meeting
a filthy m*rder*r like him?

How about we make today
our first day as a couple?

Help me, Dr. Brain!

-Hold me.
-I will k*ll you.

No!

You'll become a m*rder*r.

No, Dr. Brain.

No.

No.

What...

What?

We did it.

I can't hang on any longer.

No, Yi-na.

Yi-na.

Yi-na.

Wake up, Yi-na.

Don't fall asleep.

Yi-na.

Yi-na, no. Yi-na!

-Yi-na.
-No.

Detective Geum.

What? Why is the water still running?

Was it a lie?

-No.
-Lift your head.

Lift your head.

Yi-na, lift your head!

-Yi-na.
-Your head...

Yi-na, lift your head!

Mister!

Please just let my daughter go.

-Are you okay?
-Yes.

It's okay. The valve is shut.

But where could that be?

I think I know where they are.

I saw the name of the bathhouse earlier.

Let's go.

It's so cold.

My pretty face is going to freeze.

-Run! Come on!
-Detective Geum.

Follow us!

What's going on?

Are we chasing or being chased?

What happened?

-Mom.
-Yes?

I can't do this anymore.

-My head hurts.
-No, Yi-na. Stay awake.

Yi-na, the water's stopped running.
Hang in there.

-Yi-na.
-No!

Yi-na!

-Auntie!
-Oh goodness!

Yi-na!

-Yi-na!
-Auntie!

-Yi-na!
-It's okay now.

Are you okay?

Dad's here.

Get Yi-na first.

Detective Geum.

They might get hypothermia.
Take them all to the ER.

-Okay, I'll call them.
-Get Yi-na first.

-Myeong-sae.
-Dad.

I got the stopper out.

Get over here and help them out.

I got the stopper out.

Good job, sir.

Hey, kid.

It's time for the last game.

You know where I am, don't you?

Detective Geum.

I'll leave them to you.

Where are you going?

I have to go meet Hwang Dong-woo.

-Are you all right, Yi-na?
-What is this?

This needs to be undone.

Welcome.

You have a triumphant look on your face.

Of course.

I did win an impossible game.

I must say, it was very thrilling.

I should thank you
for giving me the chance to participate

in such an incredible brain experiment.

I hope

you're not deluding yourself

into thinking you were actually
empathizing with that detective.

You saw it with your own eyes.

No.

You're incapable of doing that.

Your high intelligence allowed you
to trick your brain momentarily.

You know very well
that your brain is incapable of empathy.

No.

My brain

has transcended its limitations.

We cannot transcend our limitations.

You're wrong.

You can overcome them
the moment you connect with others,

just like how Detective Geum

helped me become a better person.

"A better person," you say?

Do you truly mean that?

Of course I do.

Fine.

Then how about a round of Truth or Dare?

We'll find out whether or not
you truly believe what you said.

If you do, it'll be a match.

If not,

it'll be a mismatch.

Fine.

What are we betting?

Our lives.

Meaning that one of us

will disappear from this world.

This is morphine.

The winner
will inject the loser with this.

What do you say?

Are you in?

I'm in.

We'll go inside and search every corner.

We must catch them no matter what.

Yes, we'll catch them at all costs.

Go with them and see a doctor.

I'll wrap things up here
and catch up with you.

-Okay.
-Hurry, Dad.

That man who was with us
is in on this too.

Make sure you catch him too.

Okay.

Wait.

Have you heard from Ha-ru yet?

So?

Should I go first?

No.

I'll go first.

All right then.

Human connection

helps our brains
overcome their limitations

and helps us

become better people.

I...

am living proof of it.

Humans live according to the way
our brains are programmed.

The human brain

can never transcend its limitations.

Okay!

I won.

See that?

The only person uncertain of his truth

is you.

This can't be.

Something's gone wrong.

No.

You may not want to believe it,
but your brain does.

The moment you saw my brain empathize,

your brain realized it.

"I was mistaken. I was wrong."

"I can

overcome my limitations."

No!

Something went wrong! I'm sure of it!

Why?

Are you afraid now that you have to die?

Of course not.

In any case,

you won.

I shall die in your hands.

Inject it.

All you have to do
is stab me with the needle.

You'll finally be getting your revenge.

Injecting it into my neck
wouldn't be a bad idea either.

Either way, go for it.

Let's do this in one go.

Do a clean job, will you?

Because that's how I k*lled your parents.

Nice and clean,

in one fell swoop.

Shut your mouth!

Your beliefs are wrong.

I am...

not like you.

Make your choice.

You can either

rot in prison for the rest of your life...

or commit your last m*rder.

There's only one person you can k*ll now.

And that's yourself.

Oh, right.

Before you die,
you should at least know this.

Do you know why we got these results?

It's because

your brain desperately wanted
to connect with someone.

Dr. Brain. Are you all right?

Hwang Dong-woo is inside.

Go in and arrest him at once.

Wait.

You should be careful though.

He has a syringe filled with morphine.

If he injects you with it, you'll die.

Okay.

I was never wrong.

I do not want human connection.

Hwang Dong-woo!

He seemed like a smart man.

Why did he lead such a life?

Is that also because of his brain?

It's because
he blamed his brain for everything.

He underestimated the brain.

Exactly.

Even someone with a nasty brain like yours
can turn over a new leaf, so...

My brain isn't nasty.

It's a very special brain.

Fine.

Dr. Brain with a special brain,

I was so touched.

Did the thought of me dying make you sad?

Yes, I was sad.

Really?

"I should've been the one to k*ll him."

"He can't die on his own."

I was sad with regret.

You just had to ruin the moment,
didn't you?

Did you get that?

You can't die until I k*ll you myself.

Do you understand me?

Was that a threat or a love confession?

I'm confused.

Gosh, it's cold.

Dr. Brain, wait for me!

It's cold. Hold me, will you?

Get lost.

-I can't help but stick to you.
-Get away from me.

My body must remember
our time in the freezer.

Get off of me.

I'll be reminded of your warm embrace
every time it gets cold.

Don't you dare think about that.

I can't help it.

-Stop while you have the chance.
-I can't hear you.

Gosh, it's so warm.

Get off of me!

Ji-hyeong,

I was about to call you.

I just want to know one thing.

Why did you do it?

It has been eating at me all this time.

I'm actually relieved

by the chance to come clean.

That day,

someone came by to see Jae-seong
while he was on the phone with me.

I heard odd noises,
and then the call got disconnected.

Something felt off,
so I hurried over there.

Someone opened the front gate for me,
so I walked in thinking all was well.

Jae-seong?

Professor?

We need to talk.

Why?

How did this happen?

His disrespectful behavior
left me with no choice.

He brought it upon himself.

You know how he was.

Dr. Shin has always been disrespectful

and quite arrogant.

What about Ha-ru?

What did you do with him?

So the shrewd little boy

is named Ha-ru?

He's alive.

Ha-ru, it's me!

He's outside.

If you wish to save the boy,

you'll have to make

a deal with me.

That dead woman over there.

You were in love with her,

and he is her son, after all.

What is it that you want?

Just do as I tell you,

and everything will be okay.

In fact...

since Dr. Shin is no longer with us,

I'll make you the top neurosurgeon

at Korea National University Hospital.

Professor.

The dissertation Dr. Shin was working on

will be yours.

I made the best decision I could

to save Ha-ru.

Don't use Ha-ru as an excuse.

My patience for you
is running out as we speak.

SHIN JAE-SEONG

Ji-hyeong.

I'll make an official report

stating that your dissertation

was plagiarized.

Wait, Ji-hyeong.

I'll step down

of my own accord.

I know I messed up,

but you know how good I've been
to you and Ha-ru.

Think of how much I helped you
to raise Ha-ru well.

You overlooked a m*rder.

No amount of help could make up for that.

Ji-hyeong.

In return,

I'll let you take over
as director of the center.

I'll pull every string...

Even at this moment,
you remain an opportunist.

It makes me sick.

Well,

our family here on
the Neuroscientific Investigation Team,

who were held hostage
by the serial k*ller, Hwang Dong-woo,

were rescued
when I jumped into the cold water and...

Sir,

I'm not sure that is accurate.

Right, of course.

Thank you for correcting me, my savior.

I mean,

the hostages held c*ptive
by the serial k*ller were saved,

thanks to the outstanding teamwork
of the Neuroscientific Investigation Team.

And is Dr. Shin Ha-ru
the head of the operation?

The head?

As in the leader?

This team does not rely on one individual.

We all put our heads together

to solve cases
through collaborative brainwork,

making us a truly balanced
and democratic team.

What if you changed the team's name
to Brain Works Team instead?

The Brain Works Team?

That's a good idea.

I'm the one who came up with that.

Sure.

How come Detective Geum Myeong-sae
is nowhere to be seen?

Is it true that he resigned?

Well, you see...

LETTER OF RESIGNATION

The number you have dialed...

Why on earth isn't he picking up?

Excuse me, sir.

I have something to tell you.

Sure. What is it?

About the reason Detective Geum
decided to resign...

Yes?

I was so frustrated about Yi-na's case

that I pulled the phone...

Captain, I need you
to go somewhere with me.

Hey.

Why weren't you answering your phone?

Did you call? What for?

What else?

What should I do with this?
Should I really process it?

Of course not.

I'll explain later.
I'm a little busy right now.

Captain, you must come with me.

-Hurry.
-Sure.

Where are you going? What about me?

Stay here, sir.

-Hurry. Go on.
-Okay.

Did he just brush me off?

Hurry!

-Run, Captain!
-Where to?

-Up the stairs, to the rooftop.
-Which way?

-Here?
-Head up the stairs.

What's going on?
Is someone attempting suicide?

-Don't stop and keep running.
-All right, I'll go.

-Don't stop!
-Okay!

What's going on?

What...

We're here.

Where...

What?

What?

It's not as pretty as I imagined.

There.

I heard you're more likely to say yes
when your heart is racing,

so I'll cut to the chase.

Captain.

If it's okay with you,

shall we reactivate our love systems?

If you could turn it on again,

I'll work hard to make sure

it never turns off again.

No, you don't have to do that.

Because my love system

was never turned off.

Goodness, Captain.

But would you

call me by my name now?

Sorry.

I'm so used to calling you "Captain."

Thank you so much for saying yes.

So-jeong.

I'm so embarrassed!

My goodness.

Who could be calling
at this important moment?

MY DAUGHTER YI-NA

It's Yi-na. You should take it.

Okay. Excuse me for a second.

Honey, what's up?

Hurry home and eat with us.

What?

Who are you with?

Fine. See you.

What?

Let's not bother him.

Something's up.

He's with a woman.

-I'm positive.
-So what if he is?

Your dad's single.

What?

I was just worried for you.

Didn't you want to get back with him?

Well, I thought about it,

and I think we're better off as friends.

You know my type.

-The Hollywood style.
-The Hollywood style.

You sweet thing.

Algernon, when I saw the word "match"
on the screen,

I felt such a thrill.

I thought my brain would explode.

It was the best experience of my life.

My heart's still pounding.

DETECTIVE GEUM

You want to know who it is?

It looks like
I have someone other than you now.

A friend.

Why are you calling me again?

Why should I go there when I'm not a cop?

MODEL DETECTIVE AWARD CEREMONY

This is my first award in 30 years.

This is already my second award this year.

That's a double honor.

And who made that happen?

Here we go again with your bragging.

How is it bragging when it's a fact?

Okay, fine.

It's all thanks to you.

How about a group photo?

Of course.

-Come up here.
-Okay.

Come on.

Hurry up. Stand in a row.

All right.

The Neuroscientific Investigation Team...

No, the Brain Works Team.

Smile.

Yes.

Why the awkward faces?

Did someone force you all to be here?

My gosh.

I guess I should take the lead then.

Try laughing like me.

-Laugh with me, Captain.
-Okay.

Laugh, Dr. Brain.

Laugh with us, sir.

BRAIN WORKS 2023

How's business these days?

It's the same as always.

Pour me one too.

Welcome...

Gosh.

Where are you going, Dr. Brain?

Join the team for dinner.
It's the senior superintendent's treat.

No, thanks.

Why would I join when I'm not a cop?

Come on, you're on the Brain Works Team.

You got an award too, remember?

I already told you I'm quitting,

although I somehow made it this far.

It would be such a shame

if you were to leave like this.

Quit your disturbing attempts to be cute

and go drink without me.

Wait. Hold up.

What's this? Mr. Yang?

A video call?

Detective Geum.

-Look.
-What's that?

Mr. Yang!

Wait, Dr. Brain!

Here. Look at this.

Help me, Detective Geum.

What the...

Mr. Yang!

Did you see that?
