I also had a dog.
It was named Umul.
It died in the Great Drought.
What brings you here?
It's not on the door. It's on the floor.
Sorry?
The sign for the data storage at Balhae Station
is on the floor.
CAUSE OF DEATH
Dr. Song.
Yes?
Mr. Lee Gisu is not responding to the radio. Are you with him?
He's on standby at the entrance, and I'm
taking a look around the surrounding area.
Oh, what about the biosignal?
I'm searching the nearby area, but it seems like there was an error.
I'll be returning shortly. Join Mr. Lee immediately.
Please do not
act independently.
Okay. I'll go back.
What?
It's water?
Team Two returning to command center.
Chief Gong, where are you?
It looks like an error on the machine. I'm returning to the storage.
Where's Dr. Song?
She left the area, but she's returning now.
We're going to Storage Three.
Yes, sir.
Gisu.
Damn it.
Gisu.
Gisu!
Dr. Song.
The immediate cause of his death is a cervical spine fracture.
He died on the spot.
He has a fractured skull, right arm, ankles…
His entire body is damaged.
Even if he fell from the ceiling,
he couldn't have been injured this badly.
It means he didn't simply die from the fall.
Do you believe what Dr. Song said?
Well, in any case,
the state of his body
coincides with what she said.
Soohyuk and I will take care of the rest. Please return to the command center.
Okay.
Don't let your guard down on the way.
Yes. I understand, Captain.
Why was the co-pilot in the storage alone?
Why didn't you report as you deviated?
Are you interrogating me?
Once communications are restored,
I must report back on the reasons why I lost two crew members in under an hour.
So I need to know exactly what happened.
I was just…
looking around the area.
It's my fault for not reporting. I'm--
I don't need an excuse.
I'll know once I check your bodycam.
Forget the mission.
We'll spend all our time moving the corpses.
Back when I was a kid, I'd look up to the moon and make wishes.
But this is one hell of an eerie place.
And what's going on with Dr. Song? What is she trying to do?
At first, she made us nervous over their cause of death,
then she roamed about on her own.
Who does she think she is to create such trouble?
She wasn't trying to cause trouble.
She just shared her opinion as a scientist.
I was talking to myself.
And think about it.
The least we can do is work together as a whole.
But she nitpicks over everything and keeps bringing us down.
Tell me about it.
Who could've known that there wouldn't be any intact samples left in the storages?
Our captain isn't the type who'd give up like this.
We'll end up searching through the entire station.
SONG JIAN
Gisu.
Did you see that?
He was dragged in by something.
Gisu!
Wait, right here. Now.
Isn't that a sample?
The capsule is intact.
It looks like it was kept in some kind of solution.
Wait.
This is Balhae Station. Control, respond.
This is Balhae Station.
Our comms got smashed, and the station's won't work.
What now? What do we do?
I don't think there's a problem with the internal system.
There might be a problem with the radio tower outside.
They would still send a rescue ship, right?
Of course they will.
I'm sure they're trying to come up with a measure.
Goodness.
Look at that punk. He's asleep.
Soochan.
Are you asleep?
Man, I can't believe you can…
Hey.
What's wrong with you?
Hey, what's wrong with your face?
Are you sick? Hey.
What could it be?
It didn't seem human, sir.
But it took the sample.
If that creature was aware of the sample's value,
it's most likely human.
Then it could be an intruder, like that dead mercenary at the gate.
We'll catch it and find out.
It's curved at the end.
The passage seems to continue. Should we go after it right away?
It couldn't have gone far.
Captain, where are you?
It's Soochan. Soochan just collapsed!
What now?
Doc Hong, where are you?
I'm almost there!
Do not come into contact with him!
Put on hazmat suits and wait!
What's taking her so long?
Don't worry, Soochan. She'll be here soon.
-Get out! Get out of here, all of you! -Doc Hong.
-Stay outside. Get out. -What's happening?
-Let's go. -Damn it.
What's happening to him?
-Captain. -What happened?
Soochan.
Soochan, hang in there.
-You can't go in. -No, let go.
One second. Will you let me go?
Soochan! Hang in there.
Gong Soochan. Hang in there.
Soochan, hang in there.
Please hang in there.
Hang in there.
Soochan, stay with me.
Gong Soochan!
Stay with me, Soochan!
Gong Soochan!
Doc Hong.
What's going on?
Soochan.
Wake up, Soochan.
Soochan!
Wake up, Soochan!
Air purification system activated.
Doc Hong.
Have you seen anything like this?
I've never seen anything like this before.
At this point…
we have to keep him quarantined
until we find the exact cause of death. It's too dangerous for the others.
We should move him to the main lab infirmary,
and I'll have to do an autopsy right away.
Should I talk to Chief Gong?
I'll talk to him.
Air purification complete.
I'm sorry.
We have to do an autopsy to find out the exact cause…
Dr. Hong.
Yes?
If there's a way to find out everything that happened here, what would you do?
What do you mean?
There's a data storage…
somewhere in this station.
How long will it take?
The autopsy itself will take one to two hours.
But it'll take me quite a while to find the exact cause of death.
I'd like to inspect the medical records and the other bodies.
And?
Do you need anything else?
No, I just need your permission to conduct an investigation.
I thought you didn't need my permission.
You've been doing as you like.
Don't you get it by now?
How can we get answers if we don't ask any questions?
I know this is tough.
But our mission stands the same
until we reconnect with Earth.
Captain… can we call it quits?
We don't know why he died or what killed him.
The intruder got away through ventilation shaft INP-07.
It passes through all key facilities of this station.
Soohyuk and E2, you'll search the shaft with me.
Taesuk and Sun, get us reconnected at any cost.
We'll either call for backup or halt the operation after that.
Yes, Captain.
It has to be tough on the captain too.
But for now,
we have no other choice but to do our jobs.
I have to take a look at the mainboard.
Comms are still down.
Is that made from a real meteorite?
They look like rocks, right?
But these are real.
It's like a superstition.
Meteorites fall on Earth,
but they're fine.
So we wear this to bid for our survival no matter where we crash-land.
It's a form of prayer to the deity of the universe.
I got this with Soochan,
but only I survived.
Why couldn't we both live?
Why would you believe such a thing?
-What? -Think about it.
If you die, you die. If you live, you live.
There's no such thing as a deity.
The machine room is the closest.
The west wing of the dorm is down the hall.
I'll take the lead. E2, you watch our backs.
Yes, sir.
There are logs up until right before the accident,
but I don't see any particular leads.
In that case,
don't you think they really died of a radiation leak?
SONG WONKYUNG, LEVEL 1
Oh, I can't watch this.
Have you found anything?
Some files are locked.
I see.
You probably can't look up the records of the higher-ups.
I guess not.
Showing the same symptoms, all on the same day…
It progresses rapidly
and has high fatality.
We need to secure tissue samples from other bodies as much as we can.
And I'll trace back to when Soochan's symptoms broke out.
You're going to check the bodies?
I can go alone. You can stay here with Dr. Hong.
No, you cannot move independently.
I'll come with you.
Would it be okay if we left you alone for a moment?
Sure.
I'll see you later.
Captain.
A biosignal is approaching us from the front.
Are you sure?
Yes, it's right ahead of us.
It just passed by.
It's moving back forward!
Left. To the left, sir.
He didn't look well.
He was sweating profusely
and he kept falling behind.
He'd space out and stare at the wall.
Come to think of it, it was a bit odd.
Wait.
I think I came in contact with him too.
This isn't contagious or anything, is it?
Dr. Song, I need you here for a second.
Why? I'm still collecting samples.
-It won't take long. -I'll be there right away.
I don't need you. I just need Dr. Song here for a moment.
You can stay and collect samples.
Well, I don't have much to do here, so--
I'll be back soon.
Dr. Song.
Make it quick!
Dr. Song.
What was it about this time?
It's nothing.
Let's go.
Anyway, Dr. Song. This really isn't contagious, right?
I suddenly feel itchy all over.
What's in here?
There are no indicators for Level One facilities.
It's located right next to the machine room.
Captain.
Are comms back up?
I found a way to fix it, but things don't look too good.
Okay.
Let's head back to the command center.
-Yes, sir. -Yes, sir.
I'm sure everyone here
came down with some kind of sickness.
How else would they have ended up like this overnight?
Thank you, Dr. Hong.
I figured we should look into as many things as we can.
Anyway, the result came out as I expected.
I found mucus foam around the airway and bronchial tubes.
And there were signs of water seeping through his internal organs.
That means his body was filled with water.
Then,
he did drown to death.
Yes.
There's no sign of external damage.
That means the water rose up from the inside,
and it happened so quickly that his bronchial tubes are swollen.
Other bodies shared similar symptoms.
I've never seen anything like this.
Where did that much water come from? Have you ever seen anything like this?
There's nothing.
What's not there?
Nothing is out of the ordinary.
There are no infectious particles such as viruses or bacteria,
or toxins related to organ damage.
The crew members were all in good health.
Look at this.
This is Soochan's blood.
There's another layer.
In the blood? What is this?
There's a problem with the digital unit connected to the communications tower.
We need someone outside to switch the equipment
while another edits the protocol inside.
Then we reboot the system.
But I'm the only engineer here,
so I can't cover both ends at once.
Is this the digital unit?
Yes. But there's a problem.
While the station was up, you could just use the elevator
to the common wing of the building, but it's currently out of order.
The station was neglected for five years after the accident,
so there seem to be some problems.
The only way to get there is to go out to the gate,
grab the elevator rail outside, then climb down. But that's--
We can set up an anchor and get down.
It won't be hard.
No, you can't.
It's better to wait until the rescue ship comes.
-It's way too dangerous. -I'll do it.
Tell me what I need to do when I get there.
Will you be all right?
I have to reach Director Choi as soon as I can.
Did you find the cause?
We're analyzing the substance we found in Soochan's blood.
Once comms are up,
I'll make a request to Director Choi for a reinvestigation of the accident.
Only if we can find samples and have enough time.
And to do that, it's important to find out why Soochan died.
Understood.
Captain.
Are you really going out there?
Yes.
Wait.
There's something that concerns me.
It's the intruder.
It didn't try to hurt me.
How can you be sure of that?
There's something called critical distance.
When animals find intruders in their territory,
they watch them first.
Then they attack the intruder when they come within a certain distance.
That's why it's very important to keep an appropriate distance.
On top of that, it moves by using the shafts,
and it always manages to escape because it's always a step ahead.
It seems like it's familiar
with the internal structure.
Do you think it could be a survivor?
The government would have known if there had been a survivor.
Above all, it has been over five years.
How could there be a survivor?
It's not completely impossible.
The radiation level in here turned out to be normal,
so if they rationed food and water,
there could well be a survivor.
Then why haven't they informed us to this day?
And if it wasn't an intruder, there's no reason to steal the sample.
If it really was a survivor,
they should be welcoming us instead of attacking.
