[phone buzzing]
Hello, Dr. Jeong.
Yes.
Sure.
Is it possible for you to switch shifts
with Dr. Jeong today?
I don't really know why,
but she can't make it in to work.
Yes.
Thanks.
-Everything okay?
-Oh, you're in early.
-What's wrong with Seok?
-[sighs]
She called and said
she can't come in to work today.
-The bypass surgery is today.
-I know.
Could she be sick?
She sounded okay on the phone.
[Seguk] It's obvious, isn't it?
I bet she just ditched work
'cause she's burned out.
Honestly, can you think of another reason
why she would miss a bypass surgery?
-She's obsessed with surgery.
-Hey.
[sighs]
[panting]
She went home.
She told me
she needed to pick up some winter clothes.
Really?
ONEUL OTOLARYNGOLOGIS
[doorbell rings]
-[sighs]
-[Uyeong] What happened to your face?
[door opens]
[sighs]
[Uyeong] Seok rents this house
from a grandma she's close with.
It's at a cheap price apparently.
[sighs]
I just wish it was closer to the hospital.
Grandma?
-She has family?
-What?
Oh…
She's not related to her.
They're just close.
Just an old lady she's close to?
Yeah.
There was only enough for one coffee.
So what happened then?
Your face looks terrible.
How observant of you.
Drink up.
I'm fine.
You can have it.
Well, I'm fine too.
Oh, no thank you.
What's wrong?
[Dr. Choi sighs]
All right, fine.
-Uyeong.
-[chokes]
-Yes.
-Go out and get her some meds.
[clears throat]
Sure.
[door opens]
[sighs]
What's with all those books in the yard?
It's stuff I don't need anymore.
So I'm getting rid of it.
These days doctors tend to specialize
in a particular field,
like vascular surgery or tumor removal.
They'll even focus on a subtype of surgery
within that field.
So what?
I mean, some doctors also
only perform TSA procedures,
while others spend their whole entire day
coiling aneurysms
and then calling it their speciality.
I want to learn everything, do everything.
So I can be just like you.
Yes, I do it all.
Why'd you miss work today?
I would appreciate it
if you wouldn't lie to me.
[scoffs] I wasn't going to
in the first place.
[sighs]
Here's the proof.
It's right here.
-What?
-We're the same,
you and I.
We're the same how?
-What are you saying?
-I'm saying I can see right through you.
Once again, don't lie to me.
I'll know if you do.
[scoffs]
What possible reason would I have
to lie to you?
Why are you really doing this, huh?
So I skipped out on one day of work.
I already told you
I slipped on ice on the way here.
[sighs]
[sighs] Be right back.
[door opens]
Geez. What an asshole.
[line ringing]
You son of a bitch. Get back here now.
You brought Dr. Choi here
to screw me over, didn't you?
I've always known. I've always known
you were really a psychopath deep down.
But I still can't believe
you're doing this to me.
Get back here. Hurry back
and get him out of my house right now.
After the pharmacy run.
Forget the pharmacy!
Just turn the damn car around already
and tell him it was closed!
Okay, fine. You win.
[gasps]
Who is this guy? Why is he here?
I've never seen him before in my life.
That's the truth.
[stammers] I opened the door,
and he followed me in.
[grunts, shouts]
-Hey! Hey! Get off! Get off me!
-Stay still!
Get off!
Shut up, damn it.
Get off me, you bastard!
[groans] Let go of me!
-[assailant screams]
-[grunting, panting]
Ah, you fucking bitch!
[Seok] It was self-defense.
I promise you that.
Well, then…
What are you going to do now?
I'll bury him
later tonight
in the woods.
[Dr. Choi sighs]
Can you take care of it by yourself?
I'll call you.
Yeah.
[engine starts]
Can you take care of it by yourself?
[gasps]
Wait a minute!
Wait a minute, wait a minute! Hold on.
What?
You have something to say?
No.
It's nothing.
Nothing.
[chuckles]
Tomorrow then.
Nice and early.
Go.
See you later!
HYPER KNIFE
[phone buzzing]
[Seguk] Yes.
Oh. We're still in Busan, sir.
Oh, the director and everyone else,
they all left earlier.
Oh, sure. Just a second.
Yes, Dr. Choi. Your laptop?
Sure. And where should I bring it?
One moment.
[reporter] The body, identified as
a former nurse, was found in the mountains
behind an abandoned temple located
on the outskirts of Changnyeong-gun.
Police have announced plans to conduct
an extensive search of the area
around the temple in an effort
to gather additional evidence,
as they suspect that an organization
involved in illegal surgeries
murdered her to cover up their own crimes.
-Finding all of it is gonna take forever.
-Believe me, I know.
We're doing it little by little.
But we really need more hands out here.
[Seo] You said we were just gonna
take a quick look.
Come on. We should go.
[sighs] Can we please just go? Oh, shit.
[officer] Everyone move, please.
Thank you. Thank you very much.
-Excuse me. Please.
-Coming through!
Move the car over there!
What could you possibly need to see
right now? Can we please go?
-[officer] No pictures!
-Just relax, would ya?
[sighs] Seriously.
Neither of us should be here, ya know.
-No, no, no. This is a crime scene, okay?
-Why not?
Criminals return
to the scene of the crime.
Do they not?
[scoffs]
Your nostrils just flared, didn't they?
You're trying not to laugh!
Not true. [clicks tongue]
Yeah, right.
Have you lost your damn mind?
You're seriously deranged!
[chuckles]
This is a totally new experience for me,
so it's just interesting.
Wow. Just look at all these people here.
Wait. Does that make you happy?
Do you feel all superior or something?
Like you're some big shot now?
That what this is about?
You think I'm a psychopath, huh?
I'm just saying it's interesting.
I know you think so too.
No, I really don't.
I don't find this interesting. It's scary!
You should be scared, too!
Everything we buried.
It's all completely burned, right?
You were the last one to check it,
weren't you?
What's Dr. Choi doing here?
Ah, man. Those bastards.
They made sure to torch everything.
Kim, give me some gloves.
[Dr. Choi] Mannitol.
It removes excess water from the body.
A neurological drug?
It's prescribed to reduce eye pressure
or treat renal failure.
It's used in my department too.
For neurosurgery?
Mmm…
Oh, no. What are you thinking?
You stay right here.
[chattering]
[radio dialing]
[officer] Search Team 3 here.
We found the victim's belongings.
It's her purse.
-Can you confirm it's the victim’s?
-We found her ID card in the wallet.
We'll send it over
to headquarters immediately. Over.
What did they find?
-[phone ringing]
-Mmm.
The victim's purse.
Yeah, Lee. Go ahead.
[Wanil] You're with Dr. Choi, right?
-Yeah, why?
-Um…
One of his students is waiting for him
outside. Could you please let him know?
-Yeah, all right.
-[line clicks]
He must be here with my laptop.
-Sorry for the trouble.
-Not at all.
I know you're busy.
I had the rest of your things
sent to your house.
Good, thank you.
How long are you staying here?
[sighs] Well, we'll see.
[Wanil] Dr. Choi!
Why is he being such a good boy today?
He usually doesn't let anyone touch him
except for his partner.
Do you like me?
'Cause I like you!
[Wanil chuckles] Your student seems
to be something of a dog expert.
She owns dogs. She has quite a few.
[Wanil] Makes sense.
What kinds of dogs?
Rottweilers.
[Wanil] Rottweilers?
Aren't they really aggressive?
They're absolute sweethearts.
Uyeong Ha. Hey.
[stammers] Hey.
[sighs]
[Seok] What exactly are you doing here?
[Dr. Choi] What about you?
You shouldn't be here.
This is about the award, huh?
Because I took it from you?
You must be out of your mind.
What were you thinking
showing your face here?
It is, isn't it?
You're suddenly hanging out
with the cops now?
'Cause of your precious award.
You're pissed off.
Do you have any idea where the hell
you are right now?
There's only so much madness
I'm willing to overlook.
You think scaring me
into performing your surgery will work?
Not a chance.
Going around killing people,
you're pathetic!
Oh, I'm the pathetic one?
Myeongjin Kim.
-You're a murderer too.
-How dare you say that?
We are nothing alike!
We absolutely are.
I'm glad you had my pharmacy closed
because now I have all the time
in the world.
Do what you want.
You can keep trying to put the pressure
on me.
I'm gonna find Myeongjin Kim
no matter what it takes.
When I find his body,
I'll give you a call.
[sighs]
[Dr. Choi sighs]
That's the girl who was messing with you
before, isn't it?
What the hell is she doing here?
Who knows?
She gets pissed off
by the mere thought of me.
Has she forgotten what she did to you?
[chuckles]
[chuckles]
-What is it?
-Ah, no. Nothing.
[Dr. Choi] We are nothing alike!
Hey, do you remember Eunsim Han?
She was in our class.
Uh… Eunsim Han?
[Myeongjin] She was the girl
who got married in a rush.
All of us went to her wedding
even though it was really short notice.
[chuckles] We even did a collection so she
could have some cash as a wedding gift.
Remember?
Man, those were the days, huh? [chuckles]
[person] Hi. How are you?
YONGHYEON CATHOLIC CHURCH
[Dr. Han] Hmm… You've been
having heartburn, is that right?
-[patient] Yeah.
-I see.
Well, in that case, you should come
by the clinic so we can run some tests.
-You know where it is?
-Of course. Thank you, Doctor.
Why would you help him?
You've got your own problems to deal with.
His father is dead.
I feel bad for the guy.
You don't know he's dead.
I thought he ran away.
Well, I know he was killed by Dr. Choi.
[sighs] That doesn't make any sense.
Why would Dr. Choi want to kill anyone?
Not everyone is like you.
All humans are evil.
That's just the way it is, you know.
Will you stop already?
Oh. He's here.
Well, best of luck helping him then.
I'm going to stay here.
And do what?
Hope that you snap out of this
and then come to your senses!
What's with you?
[reporter] These are shots
from a psychiatric hospital in Donghae
that was shut down last month.
A police investigation has revealed
that a shocking 40% of the patients here
in this hospital
were involuntarily admitted.
[victim, distorted voice] On the days
when the government came for inspections,
they'd shove drugs down our throats.
We were all high on those drugs, so
-of course we looked like mental patients.
-Your dad was one of the patients here?
We were trapped.
Someone reached out
and said they saw him there.
-We never should've been admitted there.
-Are you sure?
I want to go find out.
Will you come with me?
Dr. Song.
Work been keeping you busy?
What does it look like to you?
[Wanil] Well,
when can we expect to get the results?
It's not like I'm just sitting around.
So stop being so pushy.
[chuckles] Okay.
[gags]
Mmm.
So you went out for drinks last night
with Wanil, right?
-Well, just a beer.
-[phone ringing]
ADMINISTRATOR LEE
-Who is it?
-It's Sojeong.
I've been too easy to reach lately,
so now I'm playing hard to get.
Young or old, women are all the same,
you know?
Hmm? A bit of neglect. They like that.
[door opens]
-Hello.
-Ah, Detective Lee.
-Wanil, you made it.
-Yeah.
-Have a drink.
-Oh. Thanks.
[grunts] Wanil, ya little shit.
How did it go at the NFS?
Ah. Check this out.
Oh, not now, not now. Do it later.
Can I please take a look?
[chuckles] Of course you can. Please do.
Here.
This picture.
Ah, that.
It looks like some animal fur.
But they'll let us know for sure
once they get the lab results in.
Eunchae Song is the examiner?
[Wanil] Yeah.
[Yang] You should've told her
to expedite our case.
[Wanil] I did.
But she really snapped at me.
DONGHAE JEIL MENTAL HOSPITAL
DANGER - NO ENTRY
See you later. Okay, thanks. Bye.
Hello there.
He's the one who called you yesterday.
-Ah…
-Hello.
I sent that email to you a while ago.
I have no clue when that was.
But I never heard back.
So I thought he was found.
Come on then.
I never threw this away,
just in case.
He was in Room 401 in the locked ward,
and his name was
Seokgu Lee.
Myeongjin Kim wasn't his name?
Mm-mmm.
Well, I don't know
why his name's different.
But what I do know is that's him.
It's definitely him.
You have any photos?
Why would I go around taking pictures
of patients? That'd be weird.
Then how do we know
this Seokgu Lee is really his dad?
What actual proof is there?
[handyman sighs]
Because I told you it's him.
[clicks tongue]
So,
um…
This patient named Seokgu Lee,
where is he now?
How should I know where all the patients
went after the hospital was shut down?
Your father has a scar on his head.
You didn't write that on your flyer.
So how would I even know that?
[hair clippers buzzing]
It looked something like this.
Yeah?
Here.
Can we take a look inside of the hospital?
ENTERING WITHOUT PERMISSION
IS A VIOLATION
CEASE AND DESIST ORDER
[handyman groans]
So, the reward you mentioned,
when will I get it?
After you find your father or what?
As soon as we get actual confirmation that
he was here,
I'll give it to you.
Fair enough.
[handyman] Okay. This is it.
Let's see now. Wait a minute.
-Hang on. Uh…
-[keys jingling]
Which one is it again?
No, not this one. Uh… Maybe this one?
No, probably not.
Wait, is it?
Which one is it? What do we have here?
[jingling continues]
Are you doing all right?
[stammers]
I need the restroom. Excuse me.
[handyman] Not this one. Ah! Here it is.
[Kiyoung breathing heavily]
So this Seokgu Lee,
did he have a visitor or what?
Huh?
I'm asking if anyone came
to visit him or not.
A visitor? Someone came. I saw him once.
[drill whirring]
It was this gray-haired guy.
He showed up and took him for a stroll
in a wheelchair,
somewhere around here.
Really?
Hang on a minute. Just a sec.
Hmm.
Is this the guy?
CHOI DEOKHEE - NEUROSURGEON
DRAWS WORLD'S ATTENTION
Do you want me to keep watching her?
No, leave her alone for now.
If she's going to learn,
she must do it on her own.
She believes
the two of us are exactly alike.
But that's all it is. Simply a belief.
A misguided one.
But the truth is you two are alike.
That's what I think at least.
We are alike in a lot of ways. I get it.
However, if you look closely,
we're different.
[Seok sighs]
Hmm?
Here it is. Seokgu Lee.
Geez.
What's with these
ridiculous prescriptions? [chuckling]
Did they really give him
all these medications at once?
Look, if that's what it says,
then I guess so.
[scoffs]
That's great.
All these crazy people are gonna be
the end of us, ya know.
But look. Regardless,
we still don't know if Seokgu Lee
and Myeongjin Kim are the same individual.
-You have nothing else?
-Aw, geez. [scoffs]
Shouldn't figuring that out be your job?
What?
You two can piece together
the rest on your own.
[sighs]
My father was never here.
You're just messing with us, aren't you?
You punk,
what the fuck do you take me for?
You're wasting our time.
You little shits. I can't believe this.
You got a problem with me or something?
Proof, huh?
[scoffs] Yeah, is that
what you fucking want? Hmm?
I'll prove it to you bastards right now!
[line ringing]

[ringing continues]
-[patrons chattering]
-[friend] Hello?
Hi, hey. It's me.
Listen. Um…
-Where are you?
-Oh, I'm on a hike.
I'm having some makgeolli
before I come down. What's up?
That one time those press people came
to do a story…
We took a picture with the patients
in the lounge in Ward Two.
You remember that, don't you?
Yeah, what about it?
Do you still have that photo?
Yeah, I think so.
I need that picture urgently, okay?
You think maybe you can find it
and send it over?
You can take a pic of it with your phone.
All right, I'll send it to you
when I get home.
Thanks. Get a clear shot if you can.
[line clicks]
When I get the photo,
check it if you want.
See your dad for yourself.
[scoffs]
[handyman] These damn brats.
Uh… Fucking hell.
WILL DR. DEOKHEE KEEP HIS CROWN?
I already told you. I don't know.
[sighs]
Look at the picture closer.
I don't know what you want me to do.
I can't remember, all right?
Ah, for fuck's sake.
[sighs]
Shit.
[chuckles] And so, I thought about
getting that treatment for myself.
But my friends said, "Don't do it.
It doesn't really work
and it's a waste of money."
[chuckles] That's what I thought at first.
But I did it,
-and it actually made a huge difference.
-Oh.
Well, it hurts a little. But it works
much better than the old laser treatments.
Oh. They were lying to keep it
for themselves while I look like this.
[both laughing]
No, it's okay. I'll hook you up
with a really good clinic later.
-[gasps] Wait. Really?
-Yeah.
-[phone ringing]
-Oh.
-Excuse me a minute.
-Sure.
So, Eunchae Song,
she's pretty straightforward.
[Dr. Choi] What did she say?
You were right. She confirmed it.
Rottweiler fur no less.
The official report will be handed
to the police tomorrow afternoon.
Okay, thank you.
Make sure there won't be any issues later.
Sure, don't worry. I've got it covered.
[line clicks]
[door closes]
[Dr. Choi] I heard you filled in
for Dr. Song in the OR again today.
Yeah.
It was an AT/RT. I wanted to do it.
Uyeong is concerned about you.
He says you're addicted to stimulants.
[sighs] Whatever he said to you,
he's wrong.
It's not true.
Of course.
You're not addicted to stimulants,
only surgery.
[Seok] Here,
here
and here.
All of those pathways…
if I follow all of them
right up to the end,
what will I find?
Humanity at its essence. All that we are.
What if I die before I get to explore
all these different paths?
You will if you don't start
taking better care of yourself.
[sighs] I know I should sleep more.
I already know that.
But things like sleeping,
things like eating,
they feel so trivial now and annoying.
[sighs]
Seok Jeong.
Promise me one thing.
From now on, you will eat right
and get enough sleep.
That's the only way
you'll make it to the end.
As for these, I'm taking them away.
[chuckles]
[line ringing]
-[sighs]
-[voice mail] The person you have reached…
Why isn't he answering his phone?
-[scoffs]
-[line clicks]
Ah, shit.
Just come back tomorrow, okay?
Tomorrow morning, I'll just swing by
his place and pick up the photo.
Sound good?
You can't leave.
What's wrong with you?
You've done nothing but waste our time
all day.
You better settle this.
Get that damn photo for us!
-Ah, forget this. Move.
-No.
Seriously? You brain-damaged
or something, you little piece of shit?
You son of a bitch!
-[shouts]
-[Seok] Hey, hey. Hey, hey!
Kiyoung, come on.
-Come on! Hey!
-Call him!
You should go cool off outside, huh?
Huh? Do what I say!
[shouts] Damn it!
[groaning, sobbing]
Damn it. It fucking hurts.
[chuckles]
[groaning continues]
Let me see it.
Just forget it.
I don't want your fucking help.
I'll see a doctor.
Don't make me call Kiyoung back here.
Oh, geez.
[groaning]
[Seok] Ah, shit.
[Myeongjin groaning]
[handyman grunting]
Come on.
[sighs]
You've got some balls.
You're really wearing this?
I've tried everything
but I can't get it off.
[chuckles]
[sighs]
[groans]
Don't let Kiyoung see that ring on you.
He'll lose his shit
if he sees you wearing it.
[groans]
What was that about?
Don't let me see what? Show me now.
Nothing, it's nothing.
And didn't I tell you to go outside? Huh?
-Let me see the ring. I wanna see it.
-Hey. Wait, wait, wait!
-Kiyoung. Stop! Wait!
-Let go.
-Hey, get off!
-Hey, let him go!
[all grunting]
[Kiyoung] Hey!
Get back here!
-You fucking bastard!
-[handyman] Fuck off.
No, no. Let me go.
Show me the ring!
You fuck!
[handyman] No! No!
-Fuck you! Get off me!
-You shit!
My dad!
Where is he?
Tell me! Tell me, you fucking bastard!
Tell me!
I don't know. I don't know!
Let me go, you asshole!
You bastard!
No!
[Seok] Hey! Kiyoung Kim!
-Fuck you!
-I said where is he!
-[handyman] I said fuck you!
-[Seok] Are you crazy?
-Tell me!
-[handyman] You fucker!
-Enough. Knock it off!
-Tell me!
-Where is he?
-[handyman] Stop it.
-I don't know. Let me go!
-Where's my dad? Tell me where he is!
What the…
Show me.

DR. CHOI DEOKHEE
[sighs]
Why have you been going out
when you're practically dying?
Just finish your drink. Then get out.
-[sighs]
-What did you do to Myeongjin Kim?
You think I killed him, right?
You said it so many times,
I almost believed it.
You did, didn't you?
[sighs]
You are so unbelievably pathetic.
I want you to know something.
You should've just told me
the truth right away.
You should've said,
"That Myeongjin Kim is a bastard,
and I hate his guts.
So I need you to kill him."
And I would have said,
"Gladly.
There's no way I'd let you get blood
on your hands.
Absolutely not."
All because it's like you've always said.
I was pathetic even then!
Excuse me.
I have somewhere to be.
You were being a hypocrite,
pretending you were different from me.
And you were ashamed when I caught you!
That's why you kicked me out, isn't it?

SPEED VIOLATION
PHOTO ENFORCED
-Good evening, sir.
-Please make some rice porridge.
-You can leave after.
-Yes, sir.
[beeps]
[shower running]
[engine starts]
[Myeongjin sighs] All right, let's go.
It's a beautiful day.
[gasps] Oh.
What the…
[door opens, closes]
[sighs] Geez.
[sniffs]
Oh. Thanks.
[Wanil] Oh, what?
You didn't answer your phone, so
I wasn't sure if you were coming or not.
This place is out of business.
Whoa. Your car…
I'm sorry.
I accidentally left my phone at home.
I guess we should go somewhere else then.
You told me earlier you had something
important to tell me about Inspector Yang.
-[Mr. Choi] Buckle up.
-Uh…
Uh… If it's about him dating Sojeong
from the Prosecutors Office,
-I know.
-It's not about that.
[sniffs]
What? What's this?
Actually, I have something to ask you too.
It's about your student I met
the other day, that woman.
-Seok?
-Yeah.
Remember the animal fur we found
on the victim's clothes?
Well, we got an email
from the NFS earlier,
and it turned out to be Rottweiler fur.
The victim didn't own any dogs,
so I guess it came from the killer.
But a brain surgeon who owns a Rottweiler
probably isn't very common.
Wouldn't you think?
Agreed.
Very rare, in fact.
[sighs, grunts]
[Myeongjin] Kiyoung.
Listen, all right?
Now pay attention to what I'm saying.
["Capricorn" playing]
