You asked for me?

Is there a possibility at all that someone…

survived the accident at Balhae?

Sorry?

Never mind.

Make sure you let me know immediately when you have an update.

I'll do that, ma'am.

THE SILENT SEA

[tense music]

[tense music intensifies]

So we've now confirmed she can survive contact with lunar water?

[Doc Hong] Looks like it.

Lunar water has similar characteristics to a virus that changes each time

it comes into contact with a new host.

As we can see, a pretty major change took place

when it came into contact with this girl here.

Or at least contact with whatever they put inside her.

These researchers…

at Balhae Station, studied cell fusion and genetic recombination

as ways to make humans survive lunar water.

And the organism they created as a result

is named Luna.

Human experiments and human cloning,

both illegal.

[Doc Hong scoffs] So that means…

the reason the government shut down this station five years ago

was because they cared more about hiding the experiments

than about the results.

[Doc Hong] If this gets out, it'll cause a panic. I mean, shit.

It's considered an act of treason for us to disclose state secrets

no matter what the secrets are.

[scoffs]

You realize, even if we swear to never speak of this again,

no one in charge will believe us for the rest of our lives!

People will watch our every move,

or we might just end up dead like the crew members here!

That's why Director Choi wanted me here.

[Dr. Song sighs]

I see the logic.

She probably thought I wouldn't be able to tell the truth.

The atrocious crimes my sister committed as head researcher.

[door opening]

What happened to Lieutenant Ryu?

We aren't safe here anymore. Something's wrong.

What do you mean, Captain?

A shaft blew up during my struggle with the Lieutenant.

There was spurting water.

[tense music]

Dr. Song.

[shaky breathing]

Are you all right?

[breathing nervously]

Dr. Song!

[panting]

-[Dr. Song grunts] -[beeps]

[breathing heavily]

What is it? Dr. Song.

Let us help.

[Doc Hong] Open up!

[muffled] I'm sorry.

[breathing heavily]

[Doc Hong] Are you feeling sick?

-Dr. Song! -[Dr. Song groaning]

-Wait, I… -[Dr. Song grunts]

[Captain Han] Dr. Song!

[breathing heavily]

[Doc Hong] Why did this happen? Open up!

-[Dr. Song groans] -I'm sure we can help you!

[Doc Hong] Dr. Song!

-[Dr. Song retching] -[Doc Hong gasps]

[retching]

[coughs]

[ominous music]

[moans, whimpers]

[Wonkyung] Jian.

I thought it was something I had to do…

for the sake of everyone's future.

[alarm blaring]

[people clamoring]

[coughing]

[all screaming]

Hold on, please. Wait!

[clamoring]

Close the gate.

Hold on!

[buzzes]

-[gunfire] -[screaming]

[man] Seal the door now!

[clamoring]

[alarm ringing]

[suspenseful music]

[Wonkyung] Jian.

All I wanted to do was show you the sea.

Jian.

[suspenseful music swelling]

[gasps]

-Are you all right? -What happened?

[sighs]

You were infected just like the others were.

But somehow, your body's fighting back.

[Doc Hong] I think…

possibly, Luna's DNA,

it acts like a sort of antibody.

It suppresses the multiplication of lunar water in your body.

It could be you're just lucky.

It's too early to tell, but…

this poor girl, she just might be the key to saving the whole world.

[somber music]

She's Luna.

What?

That's her name.

[Dr. Song] Luna.

[somber music]

[Taesuk breathing heavily]

[foreboding music]

[breathing heavily]

It appears Gisu and Lieutenant Ryu

were both working for RX.

We should head to Gate Seven.

Shouldn't we hold our position until the backup team arrives here?

[Captain Han] We're out of time.

I need to speak with Mr. Kim.

[Mr. Kim] The rescue party's spacecraft has entered the Moon's orbit.

We just checked the radar, and it's just like you said.

We spotted another vessel entering orbit as well.

It's a model used by RX Corporation, which means mercenaries are aboard.

We're going to need more time to retrieve the samples.

If the mercenaries make their landing, we won't be able to get them.

Any measures you can take to delay them would be extremely helpful.

[Mr. Kim] All right. I'll see what I can do.

What's going to happen to Luna?

When she comes back to Earth, what are you planning to do?

Our experiments with Luna 073

don't even exist according to the government.

I'm afraid she'll be sent somewhere within the Ministry of National Defense.

And once she's there…

the government will pick up the experiment where the station left off.

It's too dangerous.

Lunar water is extremely unstable.

[Dr. Song] It could threaten the life of everyone on Earth.

And if Luna is sent to a facility,

you know what that means.

She'll spend her whole life as an experiment.

Did you do what we talked about earlier?

[sighs]

Unfortunately, Director Choi holds a strong political position.

So far, no one's sticking out their neck.

What's he mean?

Captain Han requested

that I try to get in touch with any high official

who could possibly overrule Director Choi.

The lunar water belongs to humanity. It cannot belong to just one country.

On that, the Captain and I agree.

[Mr. Kim] Thankfully, some in the SAA

are starting to realize that this can be the only just way.

I will come up with something

before you all return home to Earth.

[line disconnects]

The IISB.

We cannot go back to Earth.

[Dr. Song] The International Institute of Space Biology,

we should be safe aboard that station.

We take Luna to a neutral territory,

and make sure that no one can get control of her.

I can take Luna there myself.

[Captain Han] First, we take those samples back,

then rendezvous with the rescue ship at Gate Seven.

[Taesuk grunts, coughs]

[Taesuk breathing heavily]

[foreboding music]

[Taesuk breathing shakily]

[ominous music]

My God! What have I done?

[breathing heavily]

[grunts]

[foreboding music]

[clattering]

We have to let people know why Soochan died.

[clattering continues]

[door opening]

Location tracker.

For just in case.

You can put it on her…

if you want.

[suspenseful music]

[light music]

[Hajin] You just have to press it right here.

And in no time, I'll fly over to save you, Dad.

Yeah.

That means I can always come back home, thanks to you, Hajin.

Mm.

I really wish I was coming with you.

Someday, I want to see the Moon too.

You know, once I'm back, I won't leave again.

I promise you that.

You're lying.

No, I'm not lying.

First thing I'd do when I'm back is I'm going to teach you how to swim.

Swim?

It's a way to move around underwater, like a fish does it.

[scoffs]

But aren't all fish dead?

[mellow music]

[clicks, beeps]

It looks like now she trusts you.

[door opens]

[Soohyuk] Everything is ready.

We set out in your command, Captain.

[Luna panting]

[Dr. Song] As soon as Luna reaches Earth,

they'll shut her away in a lab forever.

There's no way those people will ever leave her alone.

That's her fate. Her location won't make any difference.

Luna is coming back home with us.

You're calling her Luna now.

We can't think clearly if we're desperate,

and we can't afford a wrong decision.

We've seen how deadly the consequences can be.

We just can't repeat the same mistake.

[sighs]

The only choice that I can make

is completing this mission for my daughter.

[Doc Hong] Hey…

Are you okay?

Hello?

[breathing heavily]

Something's wrong.

[water rumbling]

[rumbling]

[clanking]

[rumbling]

Luna, what is it?

Luna!

[foreboding music]

She wants us to follow.

Call her back.

This route is the fastest way to get to Gate Seven.

[Dr. Song] Let's follow her.

She knows something.

She must have a good reason to do that.

[suspenseful music]

[water gushing]

Run!

[Dr. Song panting]

Go.

[water gushing]

[Dr. Song panting]

[all panting]

Luna!

-Huh? -This way!

[Soohyuk] Hurry!

[tense music continues]

[buzzes]

What's wrong?

[Taesuk gasping]

[breathing heavily]

[loud rumbling]

[tense music]

[breathing heavily]

Ryu Taesuk.

You're already infected.

It's all over.

I just can't get them out of my head.

What?

I never wanted to do it.

I don't want to hurt anyone.

-Taesuk, just let me-- -Stay back!

-[gunshot] -[Doc Hong shrieks]

[panting]

You knew, didn't you?

[Taesuk exhales sharply]

What we did.

Why did you try to hide it?

Why did you pretend?

Why did you?

Why?

Lieutenant Ryu, why are you doing this?

We don't deserve it.

We don't deserve to have the lunar water at all.

[Taesuk pants]

I'm sorry, Dr. Song.

I'm sorry, Dr. Song. I'm sorry.

[sobbing]

Dr. Song, I'm sorry. [Taesuk cries]

Lieutenant, we need to get out of here right now!

No one's rescuing you.

[shaky breathing]

-[people clamoring] -[alarm blaring]

[all gasp]

[clamoring continues]

-[alarm ringing] -[clamoring continues]

[officer] Taesuk, close the gate.

[cries]

[officer] Ryu Taesuk!

Close it right now!

Ryu Taesuk!

[buzzing]

-[gunshots] -[screaming]

[gunfire]

[muffled screams, cries]

[in breathy voice] We didn't try to save any of them.

[breathing heavily]

They never sent us up here for that.

[ominous music]

[low rumbling]

This ends now.

[Doc Hong gasps]

Shut the door behind us!

-[gunshots] -[Soohyuk grunts]

[buzzes]

[cracking]

Officer Gong.

I don't think that I can hold out for long.

-[Soohyuk moans] -Are you okay?

[Taesuk gagging]

Sorry.

[breathing heavily, coughing]

[loud rumbling]

[Luna pants, grunts]

[Dr. Song] Luna!

[tense music]

[Taesuk gags]

[grunts]

[Taesuk croaks]

[Taesuk breathing heavily]

[Taesuk retching]

Captain, we must make your way to the airlock right away.

[water gushing]

[suspenseful music]

[beeping]

[whirring]

[suit unlocks]

[Soohyuk grunts]

-[groans] -Officer Gong.

Stay with me.

It's all right.

[Soohyuk groans]

Stay with me, Officer Gong.

Just a little longer.

You can't fall asleep. Stay with me.

You're all set.

Let's go.

Officer Gong.

Where are you?

What's going on?

[Captain Han] You should go first.

What? No.

No, we won't.

[Dr. Song] Not alone.

You said we'll go back together!

No! Open up. Get back in here!

Hey! What the hell are you doing?

You said you were finishing this mission for your daughter!

[screams, panting]

You can't stay!

Captain!

You can't stay here!

[somber music]

Wherever Luna goes…

promise you'll be there with her.

No…

We'll go there together.

[dramatic music]

[Dr. Song] Luna.

We have to leave.
