Where are all the others?
- Polaris V, the old station. - Why?
We came back for the comms.
They were looking for something...
We need to find the suitcase...
I don't think it was the radio.
We found a body buried outside the station.
It's Sarah Jackson.
We had a causality incident in the last station...
Unfortunately we lost a dear college of us,
Sarah Jackson.
It's my fault.
Sarah didn't die in the fire.
She was murdered.
They wanted to get rid of the evidence.
This was it.
This was what they were all looking for.
It's me, Damian.
Please, listen to me.
I left a gift for you. Inside Polaris.
That thing you thought you got rid of,
well, you didn't.
What I want
is for you to wake up every morning thinking that,
maybe it's still down there.
That when the ice melts,
they'll go down there
and they'll find it.
And then everybody'll know what you've done
to Sarah Jackson, and all of us.
I know you're incapable of guilt.
But fear?
That will do.
This was it.
This was what they were all looking for.
Oh, shit!
When Theseus entered the Labyrinth...
Ariadne gave him a ball of thread
so he could find his way back to her.
That phone cable,
was my very own ball of thread.
Shit.
There was nothing we could salvage.
We were trapped.
I'm afraid, by that time, we were running out of moves.
Maggie? It's me.
Can anybody hear me?
I've found the comms room.
There is nothing left. It's completely destroyed.
I think we should head back.
- Okay. - Roger that.
This way.
Annika?
Annika? Do you hear me?
Annika?
- Annika! - Annika!
Annika!
- Annika! - Annika!
Annika?
Annika.
You okay?
I...
I got lost. I...
I...
I got lost...
She had two daughters...
Annika!
She's here!
Why don't we take Sarah back?
I needed the body.
I couldn't prove she'd been murdered without an autopsy.
What do you think?
Yeah...
Yeah, I'd like that.
We don't have enough room.
Yes, we do. If we lose some of the gear.
Let's take her home.
I knew they didn't like it.
But they had to keep the charade going, for us.
Okay.
It was the right thing to do.
Her family needed closure.
She's secured.
Alright, let's do the tents and then we'll go.
Ok, just give me a minute.
Annika!
Cheescake...
I'll go talk to her.
Cherry pie, cheese...
Annika?
Are you okay?
Dream cake,
cherry pie,
and cheesecake.
What was she saying?
Dream cake...
Cherry pie?
Fuck...
Sorry...
It was blueberry.
Danish dream cake on Mondays,
blueberry pie on Wednesdays,
cheesecake on Fridays.
The dessert menu at Polaris V.
And she would always be there, sitting alone in a corner.
Head down.
Taking notes, doing some work.
- That's how you met her? - Yeah.
I was leaving at the end of the summer, so I mustered
the courage to chat her up.
And the first thing she said to me is:
"You're the guy that's eating those shitty cakes."
So I had to buy her one,
show her what she was missing.
I didn't see her until the end of winter,
after the rescue.
I went to the hospital to visit her.
Honestly, I didn't know what to expect.
How was she?
I'd seen that look before, you know?
On people who leave but...
in here... they haven't.
I brought a blueberry pie.
And suddenly, out of nothing, she started laughing.
"But it's Friday! "
At first, I didn't know what she meant,
then she reminded me that Friday was cheesecake day.
So, I got her out of bed, and we...
went down to the cafeteria, and we...
we found some cheesecake.
It was shit. It was so bad.
But it didn't matter.
We found each other again.
I hope you find her.
Why did she...
say that?
I think the T3 was getting to her memories.
That, I think it's a survival thing.
Your body...
takes you back to a time when you felt safe.
Come on.
Come on, we have to go.
Come on.
Johan, the forecast is good.
I come back to the air.
What happened next?
It's all a blur.
It's...
We went back to Polaris...
Maggie?
Are you okay?
Yeah, I'm fine.
I found this at Polaris V.
What's this?
If it's Sarah's blood, it means she was murdered.
And that's the reason for all the killings?
Yes.
One of them is the killer.
They're all involved somehow, but only one is killing for it.
And the others don't know who it is.
So he can't kill us in front of the others.
He has to wait until...
we are alone.
Help, we need to block it!
He cannot get in.
I'm sure he'll try again.
Get me some needles.
I've got enough propofol to put an elephant to sleep.
We get him, and this nightmare is over.
We had a plan.
It wasn't a good one, but we had a plan.
The problem was, he had one too.
Fifteen degrees and dropping.
He's turned off the power and the heating.
This place is insulated,
so we have some time.
- But not much. - Where're the controls?
The comms room.
He's trying to flush us out. What do we do?
Maggie?
Maggie!
You can't fall asleep.
If you sleep, you may not wake up.
Okay?
Mm...
Okay, let's talk.
Talk?
About what?
Tell me what you'll do,
once we get out of here.
Out of the infirmary?
No, I mean...
out, out.
Home.
I'll go for a beer with my sister,
celebrate my first successful polar winter.
I'll buy a ton of ice and melt it.
As revenge.
Don't make me laugh.
I just want to...
lose myself...
in something.
In someone.
Aki...
You're afraid of me?
No, it's not that...
Then what?
We can't make plans.
Of course we can.
We're trapped in the middle of the fucking ice,
and we can't get out.
Whether it's the cold, or...
the killer outside, or...
Or Erik snaps, or the power dies, or...
Or we'll just go crazy, waiting for it all to end.
We won't die...
You don't know that.
We won't.
Saying it won't make it happen.
What happened next?
What happened next, Maggie?
I'm going to make a run for it.
You can't.
You were right.
We cannot just wait here until it's over.
- Wait here. I'll go check. - Okay.
Shit.
Heating is back...
Aki!
Who was he?
Who attacked you?
I don't know.
I couldn't see his face.
Help me! Help me, Erik! Help me, help me, help me!
Help me, please. Please!
Please, help me.
Erik! No, no, no! Erik, Erik!
Erik!
Let me in!
Let me in, you fucking coward! Let me in!
I'm sorry...
I killed him...
I killed Ramón.
You had to. You had no choice, Maggie.
Maggie.
This questioning is over.
Where are you going?
Maggie,
after what you've gone through,
I can't let in good conscience...
No!
Let's get this over with.
I need to know...
I need to know!
You've come to finish the job?
You might as well.
Yeah, you keep your mouth shut. Keep your fucking mouth shut!
In the meantime people keep dying
because of your silence!
I had no choice...
Is that what you told Ebba?
When she came asking for help?
You told her to keep her mouth shut,
and now she's fucking dead!
Aki!
It's okay. It's me, it's me, it's me!
Okay.
You're okay? Come on, come on.
You're okay.
What?
Are you okay?
It's not mine.
It's okay, it's okay.
It was Ramón.
It's okay.
Sarah!
Come on, come on!
Oh, fuck.
Ramón, he wasn't working alone.
Arthur? Annika?
Oh, shit.
We were trying to figure out
why he wanted Sarah's body.
Sarah was gone and...
our chances of finding out what happened to her were
quickly disappearing.
We went to Ramón's room.
We wanted to see if we could
find something there.
And what did you find?
I can't remember...
There are still some places...
No, I can't.
If I took you there, would that help?
If we took you there.
I don't know, maybe.
We're in the middle of no where.
Hey, come on guys... hey!
This place doesn't give a shit
if we live or die.
What is going on?
Empathy will only get you killed.
Please stop, just let us go!
He could have done it...
It could be anyone.
What are we looking for?
Universidad Complutense.
He checked out this one 17 years ago,
and never returned it.
We found his phone in here.
We were trying to unlock it.
Aki!
Maybe there's something in here.
It's locked.
Fancy a guess?
Only a million combinations, easier to win the lottery.
It's all encrypted,
we couldn't read anything.
I think Aki had an idea...
All of these books,
they're fairly new.
But not this one.
He's had it for nearly 20 years.
He was obsessed with it...
So, I'm thinking...
If Pascal was his favourite writer...
A Pascal Triangle.
It's a number pattern,
every number is the sum of the ones directly above it.
Somebody could use it to create a series of numbers...
What is that?
I think we used these numbers to open the phone.
- Get the phone. - Yeah.
He could just recreate it with the formula.
- Worth a shot. - Well...
There are several options.
But it's six digits,
and the sixth row
is the first one that has six unmirrored numbers.
So, one, six, one,
two, zero.
Yeah.
Nothing recent.
He deleted all his conversations, even emails.
But he seems to have lots of pictures and videos.
What is this shit?
What is it?
This is horrible...
What kind of a person keeps this on his phone?
The kind of person that enjoys it...
The kind of person who's turned on by that shit.
Maybe Sarah found out...
That's why he killed her.
But what about the rest?
Why kill them too? Did they all find out?
What if it wasn't Sarah who found out?
This shit can send you to jail.
- If someone else knew... - Blackmail?
Maybe.
What's wrong, Maggie?
I think there was something else on the phone.
Polaris V.
This picture.
Look.
This was taken the night of the fire.
The night Sarah Jackson died, look.
The sweater.
It was him.
Arthur killed Sarah Jackson.
Are you sure about this?
I think so...
It has to have been him.
Where's the sweater?
I took it and then...
And?
- I can't remember. - Think, Maggie.
- I'm trying... - Then, try harder.
Arthur Wilde.
He is one of the most brilliant scientists in the world.
He is a very...
prominent...
and seemingly efficient researcher.
He is...
very good at what he does.
And...
we started this together and we'll finish it together.
So, I guess
he is very focused the success of his research.
His research is just amazing.
He gave me this incredible opportunity.
For me it's a big honor to work with him.
He is doing good things...
for the planet and I...
admire that.
Erik.
No, Erik.
Erik, Erik.
No!
Where's Sarah's body now? Where is it?
It's downstairs!
Please, please...
Erik.
Erik, put the gun down.
Stay away from this.
I can't let you do this, Erik.
Have you seen what he just did with Sarah's body?
You were right, Maggie.
I should've done this eight years ago.
Arthur needs to go home and answer for what he did.
Sarah deserves that.
Sarah, yes!
- But he doesn't. - Stop him, please!
You shut up!
I can't hide you anymore.
I know him better than you do.
You let him open his wretched mouth,
and you'll regret it your entire fucking life.
Let him be, Maggie. He fucking deserves it.
You see? Aki is right with me.
No! That'd be the easy way out for him.
And we wouldn't want that.
The world deserves to know what he's done.
Come on, Erik!
I can't hide him anymore.
Erik!
Erik! Erik, stay with me!
Erik!
Erik, Erik! Erik, stay with me!
He was going to kill me.
I was getting to him!
The man snapped.
He's not the one I'm afraid of.
He was going to kill you too.
Go!
Aki, what are you doing?
Run!
This is an SOS...
If anyone is listening...
please contact
the International Emergency Response Team immediately.
We've lost all of our satellite communication,
and we are in urgent need of medical assistance.
Yeah, you scared me, Maggie
I thought... I... For a moment there, I...
I just...
- What are you doing? - My name...
- is Dr. Annika Lundqvist... - Yeah...
- Are you okay? - member of
the scientific expedition at Polaris VI.
I'm not... I'm not... I'm not sure.
This is an SOS...
I think I need to see a doctor. I need to see a doctor...
Where's Lars? Have you seen Lars?
Doctor Lars Olander?
Yeah, he'll know what to do.
Maybe I can help you. What are you feeling?
Yeah...
I feel my mind slipping, you know? I...
I spent... I spent half an hour this morning,
struggling to put my boots on.
I couldn't make them fit, they hurt like hell.
And then I realized that I...
I'd got them the wrong way around. They...
I forgot what was left,
and what was right.
- Annika? - Yeah?
What happened at Polaris V?
What happened?
What happened to Sarah Jackson?
