(All characters, organizations, places, and events are fictional.)
You know who drives this unregistered truck, don't you?
You've been doing this for days.
We don't operate with unregistered trucks.
Someone saw this truck pull in here.
You know who drives it.
Who said that? Let's see that person's face.
If you keep doing this, I'll have to do something.
Maybe lodge a complaint with your police station.
Wait.
My younger brother is dead.
- He looks badly hurt. - Oh, dear...
- He's bleeding badly. - Let's call 911.
- Is he dead? - We're at...
- I'll give you my number. - There was an accident.
It really wasn't me!
You're just the same.
Even if no one else believes me, you should.
That's family!
How dare you talk back at me?
I went there to win something.
I kept our promise!
- His helmet came off. - Oh, dear...
Kang Soo.
If you find out anything, please give me a call.
Please, sir.
Please call me.
I don't know anything.
A cop should catch the culprit, not harass innocent people.
He just won't give up.
Why did you drink while the sun was still up?
He's the dead kid's older brother.
He'll follow you to no end. What'll you do now?
What do you think? I'll make him stop following me.
How?
I'll make it so that...
he's no longer a cop.
"Yoo Tae Han"?
(Yoo Tae Han)
(Dark Hole)
(Episode 10)
What happened?
(Emergency Center)
Tae Han.
What happened?
Well...
We ran out of medicine and food in the ICU.
They offered supplies, so let's take that first.
Not long ago, you were insistent on killing us all.
What are you up to now?
You went from being a sacrifice to being a guest.
It's because he gave you a chance to repent.
So accept him before it's too late.
Then you can live.
Don't be stupid.
You're just under the control of the monster.
No.
I am the only one who was really chosen by him.
Are the people in the lobby safe?
I don't think anyone here is safe.
What was the scream we heard?
Dong Rim, can you go inside and help the others?
Okay.
Those guys who support the shaman and attacked us are dead.
Did the mutants kill them?
No, it wasn't them.
Let's talk inside.
(Police)
Madam Kim.
Well...
Are you going to continue to let those people share our food?
There's not much left for us to eat.
Don't worry. It'll be over soon.
Really? Is it really going to end?
He told me...
that it's all going to end soon.
What's the matter? What's going on?
The mutants didn't kill those men.
It was the monster's tentacle.
The monster we saw before we headed to the supermarket.
Tae Han, what is she saying?
"The monster's tentacle"?
Remember when we were looking for survivors on the fifth floor?
Do you remember what I said...
after I talked to the detective on the radio?
Hey, Detective.
You might not believe me,
but I saw something amid the smoke.
There might be more to this than just the black smoke.
What?
I told you there might be something amid the black smoke.
Yes, right.
It's a monster that controls the black smoke and mutants.
What... What do you mean?
Are you saying that the monster is inside the hospital?
Then shouldn't we get out of here?
It's useless to run away.
It followed us here.
What do you mean?
The first time I saw its tentacle was when I was at the school.
The second time was...
when we escaped from the school and hid at the office.
After that, I saw it at the supermarket.
Then I saw it here at the hospital.
So you're saying it followed us all the way from our school?
This can't be a coincidence.
Then how did it follow us without us knowing about it?
It seems to be intelligent...
seeing that it appeared through the vent.
Excuse me.
What?
Is the shaman really that powerful?
Don't you dare call her a shaman.
- Then what is she? - She's no ordinary shaman.
She was chosen.
"Chosen"?
When you came inside the hospital,
did you see how the smoke doesn't come near this place?
Look. There's no smoke outside.
It's clean.
It's all thanks to Madam Kim.
And she does more than just make the smoke disappear.
She can even tell who's going to die.
- She's right. - She's right.
Are you serious?
If you stay with them, you could end up dead.
I advise you to quickly join us.
That way, you will survive.
But you people know nothing. Let's go.
Come on.
If it left through the lobby,
don't you think we would've seen it?
He's right. We kept watch just in case the shaman...
might try to do something again.
But why did the monster flee toward the lobby...
where there are lots of people?
Wouldn't that be riskier since it could get caught?
What if the safest place for the monster is...
where there are a lot of people?
When we came outside the hall, the vent was already open.
The lobby was the only place left for it to go.
Exactly. Then where is it hiding?
What if it's not a place?
What if it's hiding inside someone?
What?
Are you saying it might be using someone's body as a host?
If I'm correct,
the lobby would be the most perfect place for it to hide.
So if it followed us from the school...
all the way to the hospital...
That means one of the survivors from the school...
might be the monster's host.
Yes.
When we were attacked by the monster,
there was someone who was never with us.
Who's that?
No, wait.
We don't know much about the monster.
We can't just suspect people based on assumptions.
To be honest,
I inhaled the black smoke.
Soon Il, let's hear her out.
She inhaled the black smoke.
What if she turns into a mutant?
Inhaling the smoke doesn't always turn you into a mutant.
I started hearing the monster's voice...
ever since I inhaled the smoke.
And I'm sometimes able to see things in the eyes of the mutants.
It's as if I'm connected to the monster.
How are we supposed to believe that?
She's right.
All she ever did was help us. She never once attacked us.
Do you remember how I was the only one...
who heard the high-frequency sound when the mutants left the school?
That sound is what the monster uses to control the mutants.
We are survivors who were hiding somewhere else.
Oh, yes.
When you guys were in danger on the rooftop,
I saw you guys from the eyes of the shaman.
That's how I was able to go there.
Does that mean the shaman also inhaled the smoke?
Yes, I'm sure she did.
I also think this is complicated.
But what matters is that the detective saved us.
Let's try to have some faith.
Then tell me.
Who's the person that wasn't there when you were attacked?
Dong Rim and Ms. Na.
It can't be Dong Rim.
You know very well that she hasn't shown any symptoms.
I know. But...
they're the only ones who weren't among the crowd.
No one knows what might've happened to them.
Hyun Ho.
Ji Hye.
You might not change even if you inhaled the black smoke.
Are you sure?
Yes, I'm sure.
The detective here inhaled the black smoke...
but didn't turn into a mutant.
Are you saying I won't turn into a mutant?
Yes.
So please hang in there a little longer.
Okay, I will.
Here you go.
Aren't you going to eat?
I'm fine. Go ahead.
My mom once told me...
whoever you share food with becomes your family.
"Family"?
So please eat some.
We're family? Does that make me your big brother?
Hey, we're the same age.
You were born in November, and I was born in April.
Think of me as your big brother from now on.
Hey, that's ridiculous.
Is that how you talk to your big brother? That's rude.
- Help me. - Ms. Na!
No...
When people find out that you're a murderer,
what will people think of you?
You're a murderer. You're the one who killed my dad.
No. I'm not a murderer.
Do you think people will believe you?
It's true that you lied.
Everyone's the same! You lied.
You practically killed him yourself.
You are a murderer.
Hyun Ho, the woman is back.
She must be here to take our Him Chan away.
Go away! Leave us alone!
I'm going to the bathroom. Stay here.
Okay.
Ji Hye.
Good job.
Good job, Ji Hye.
Why are you hesitating? You could kill her first.
Go ahead and kill her.
Go on.
Are you saying the two of them may have become hosts...
and we should keep a close eye on them?
Yes. I think it's highly likely.
What's the matter?
The music teacher is acting strange.
What do you mean?
Well...
She suddenly grabbed scissors and followed Dong Rim out.
Dong Rim.
Are you here?
It's okay.
It's your teacher.
Can we talk for a minute?
What I said is right.
You are a murderer.
(Restricted Area)
No. I'm not a murderer!
I'm not... I'm not a murderer.
- Dong Rim, are you okay? - What are you doing?
I'm not...
Dong Rim, are you okay?
It wasn't me.
I didn't do anything wrong.
It wasn't me.
Stay here for the time being.
Don't do this. Please.
I'm not a mutant.
Will you hear me out?
Trust me. Please.
I didn't do it. Wait!
It wasn't me.
I didn't do it.
Please.
- Is this really okay? - Hey!
It's become clear that she's a threat.
Then shouldn't we do something about the detective too?
Let's go.
(Storage Room)
Luckily, the wound isn't deep.
Let me know if you need anything.
What happened between the two of you?
Mr. Choi, can you excuse us for a second?
Oh, sure.
No one would tell me anything.
No one.
Ms. Na, please tell me.
You knew about my dad's accident.
I have nothing to tell you. I already told the police everything.
You're lying!
I know you lied to the police.
You're being ridiculous.
What makes you think I'm lying?
Do you consider yourself a teacher?
No. Are you even human?
You're a monster.
You're a monster like everyone else.
I'll catch the culprit.
Once the world goes back to normal,
I'll catch the hit-and-run driver...
and makes sure he or she is punished.
Are you serious?
I promise.
But I need you to promise me something too.
If any strange, inexplicable things are happening to you,
can you tell me?
Are you okay?
Yes, I'm fine.
I just had a little headache.
I've done everything you've told me to.
So please tell me.
Tell me the only person who was chosen by you...
is not that woman, but me.
What are you trying to do?
You know that...
I am the only shaman who is capable of serving you.
Do you think you can handle me?
Why would you say that?
Why can't you be satisfied with just me?
Keep still and do nothing until I command you.
Unless you want to die.
It's because of her.
It's all because of that witch!
What did you do to the teacher?
She's locked up in storage.
Why did she try to kill the girl?
Don't you think she tried to kill the girl...
because she noticed she's a host?
I think we should block the ventilation shafts first.
And then?
Just in case, find a place to hide.
The whole city is filled with smoke.
Where can we go?
Didn't this hospital recently buy a drone for medical use?
Yes, we did.
Detective Lee and I will go to the rooftop to look around.
Can the rest of you block the ventilation shafts?
I'll get the drone from the ER.
You two can wait for me upstairs.
Be careful.
(Storage)
Is someone in there?
Get me out of here.
- Ms. Na? - Yes. It's me.
Why are you locked up in there?
The others locked me up.
Please let me out.
Excuse me.
What's going on?
The teacher inside tried to hurt Dong Rim.
So we locked her up.
Don't worry and return to the others.
Okay, then.
(Police)
Let's hurry.
- I'll do it. - Okay.
- I'll pass you the stuff. - Okay.
They're locking people up now.
What do you mean?
They locked Ms. Na in a storage room.
What? Our music teacher?
Yes. I was coming back from the toilet...
and I heard her in the storage room.
Why did they lock her up?
They said it's because she's dangerous.
But who knows? They might be up to something.
Will they lock us up if we do something they don't like?
Right?
What's going on?
Get off the chair. Let's have a look.
This is... Gosh, it looks too flimsy.
Do you think there's some plywood?
I'll look around to see if I can find something better.
- Okay. - We'd appreciate that.
- We'll finish up here. - Okay.
Let's have a look.
- Hold the chair. - Okay.
This is a joke. It's pretty and nothing else.
Do you call this blocking the shaft? Do you?
- Why did you take it off? - Darn it.
(Restricted Area)
- What are you doing? - I'm not...
Dong Rim.
Are you okay?
(Emergency Medical Drone)
(Emergency Center)
The smoke backed off.
It was like this at the school too.
(Emergency Medical Drone)
Wait. Can you head toward the light?
What is this place?
It looks like a chemical plant.
(GPS malfunction)
What did we just see?
He was wearing a mask.
There's a survivor.
(Muji Chemical)
I think the lobby's safer than this room.
You'll head to the lobby?
You should think about it unless you want to get locked up.
The shaman said we must come before him if we want to live.
Shoot. I'm going too.
You too?
Didn't you hear they locked up our music teacher?
The people here are weirder.
Do Yoon, don't you think they're a group of traitors?
After all the detective did to save us, right?
It'll take forever with that driver. Just smash it.
Is there a hammer?
Wait, wait.
Where are you going?
We're going to the lobby.
You can't just leave. You're safer here.
How can you say it's safer here?
Pull yourself together. You're being duped by that shaman.
You should watch what you say.
Who are you to say what we can or can't do?
I decide where I go.
Let's go.
What are you doing?
Don't mind us. Just step aside.
Fine, leave. You need to suffer to see the light.
Kids, not you too.
Sorry, Mr. Choi.
(Storage)
What's the matter?
It's nothing.
Wait.
(Storage)
Did you guys see Ms. Na?
She broke the cuffs and disappeared.
What? Does that mean she's the host of the monster?
How else would she have escaped from there?
We don't know what happened yet.
First, you need to block the vents.
Wait.
Did you see anything on the rooftop with the drone?
I think there's a survivor in a chemical plant.
"A survivor"?
He didn't seem like a mutant,
but we're not sure if that place safe.
I'm sure it's safer than here.
Let's just go there.
This place is a mess with the shaman, mutants, and a monster.
"Monster"?
What monster?
Give me your hand.
What?
I'll draw you a sign that shows you've become the chosen one.
If you do as I say, you will survive.
Okay, I will do everything you say.
Hey, you.
From now on, you will be my trainee.
Your trainee?
It means you will be my favorite.
I bet you're pretty upset.
Those new guys totally took over.
Where are those other guys wearing hiking clothes?
Where are you going?
To find them.
Aren't you going to come with me?
Me?
Are you going to disobey Madam Kim's first trainee?
Get up.
My gosh, where in the world are they?
I hope they're not sleeping somewhere.
Oh, my goodness!
My gosh, what happened?
My goodness.
They did this.
What... What are you talking about?
Don't you get it?
Those people in the ICU betrayed Madam Kim...
and killed these guys.
Madam Kim!
Madam Kim! Madam Kim!
Madam Kim! Those darn imbeciles...
Watch what you call them.
Do you want to bring bad luck and die?
What?
He's among them.
What? Among those imbeciles?
I mean, he's in the ICU?
Then why did he kill his followers?
You fool.
They should be the least of your worries.
What?
Your mother.
My mom?
Madam Kim, did something happen to my mom?
That doctor...
I was wondering if I could see my mom.
I told you last time.
They're in intensive care and we can't let them be exposed.
Don't worry about your mother and stay with the others.
My mom's really okay, isn't she?
Yes. She's just fine.
I'm the only one you can trust here.
Don't trust anybody else.
(Isolated Ward)
What is this place?
Mom...
- My gosh, what... - My goodness.
- Should I do it? - No, it's okay.
Are you scared?
Is there really a monster here?
Do you know what monsters fear the most?
The ultimate item?
What?
It's a game item...
that's so powerful that it can beat any monsters.
Do you want me to show you...
the ultimate item that can beat any monsters?
Can you do that? Show us.
Of course. Give me just a second.
Ta-da. Doesn't it look so cool?
Here you go.
As long as you have that, you can beat any monsters at all.
So don't be afraid...
and stay strong, okay?
Okay.
Chan, you're so lucky.
Hwa Sun.
Do you really think we can catch the monster?
Why are you asking that?
To be honest, I'm not sure...
if we'll be able to do that.
Don't be afraid.
You being afraid is exactly...
what the monster wants.
Dong Rim.
The monster might be...
hiding within one of us.
Could it be the music teacher?
Nothing is for sure yet.
But I'll find out who it is no matter what.
I'm jealous of you.
What?
You're such a strong person.
All I ever do is give up and hide.
I've never even had the courage...
to ask others for help.
I'm really happy that I met you.
Where am I? What's going on?
What's this?
You...
You wench! Where's my mom? Where is she?
What did you do to her?
I have something to ask you.
There's something...
in the hospital right now.
And the men who were staying with you...
were killed by it.
I think it's within someone right now.
Do you have any idea who?
You despicable wench! Why are you asking me that?
It's because you lot believe the monster is a deity.
What are you talking about?
Get ready to welcome a guest.
Who's coming?
You'll see.
- Madam Kim. - Madam Kim.
I want everyone to leave them alone. They're our guests.
No way.
You know something, don't you?
That must be why Madam Kim referred to that woman as a guest.
What are you talking about?
Think about it.
When did the monster first show up in the hospital?
It all began when that woman came here.
You let a woman hiding a monster within her into this hospital!
To be honest, I inhaled the black smoke.
What's the matter?
It's nothing.
Why do you think Madam Kim has kept her alive?
It's because she was ordered to!
You'll soon die just like my mom did.
I'll kill you with my own two hands! You little wench!
You horrible wench! You deserve to die!
I'll kill you with my hands!
I'll...
kill you...
I'll...
Officer Park told me to help you.
- Can you help me move this? - Sure.
I'll go check on Ji Hye and Him Chan.
Have you found Ms. Na yet?
But I did find her traces in the vents.
Could she have moved through the vents?
She might have used emergency exits too.
Then I'll check the CCTV footage.
Okay. I'll look for emergency exits with Soon Il.
Soon Il.
What's the matter?
Hey, turn that off. Seriously.
- Wake up. - Okay, I will.
- Let's go. - Where are we going now?
To the emergency stairs.
The emergency stairs?
Fine. I guess this counts as an emergency. Let's go.
Let's get going.
Let's go.
I need to check the CCTV footage in the security office,
and I need your help.
Can you step inside for a second? I have something to show you.
(Isolated Ward)
I've been looking for a way to save people,
although I haven't succeeded yet.
Do you remember telling me...
that something is controlling the black smoke and the mutants?
Yes.
What you said is right.
We've been controlled by it all along.
What is it that you wanted to show me?
What was that sound?
What's the matter with you?
Whenever there is a new virus,
how do you think we've developed vaccines?
Do you think we just got it without any sacrifices?
You... What have you been doing?
(Isolated Ward)
I wondered why the shaman suddenly stopped the attacks.
The shaman let the people live because of you.
To protect you.
You can't be suspecting me, can you?
Whatever you are,
if you really beat the smoke,
you could provide a cure.
How dare you?
The monster's weakness.
(All child actors underwent psychological therapy.)
(Dark Hole)
I think I can find out who the monster's hiding inside.
Do they know I inhaled the smoke...
No. No one knows yet.
Why do you care so much about Dong Rim?
You'll pay again dearly for trusting people so easily.
Do not be afraid. I came to give you a present.
They're in hordes. It's a mess.
Don't talk nonsense and stop them.
Do Yoon!
Where is Do Yoon?
