You think our blood can cure you?
Blood from the family of the woman who gave birth to our people.
- We know they're in London. - Emily...
Do you know where her family are?
- Her brother. - Where?
If I take you to him, will you let us go?
I'll come back for you. I promise.
Catherine!
[Bill] What happened to Catherine?
She exposed herself
to the beamline in a particle accelerator.
Why?
Thought she could create a pathway
to this alternate reality.
She figured it out.
She was in contact with an astronaut
on the International Space Station.
He provided her with the data and formulas.
[Bill] Sent a message to the astronaut.
- What did you tell him? - The truth.
- [Juliet] Do you believe him? - As insane as it sounds, it makes sense.
He murdered a 17-year-old girl.
To save billions of lives.
I think I know what the aliens are trying to do.
They're trying to create a black hole.
The gravitational waves
will cause our neurons to fire uncontrollably.
We fall into a coma and we die.
Martha's pregnant.
Martha and her baby will fall ill like the rest of us.
Tom's blood can treat them.
The only hope we have is for revenge.
I won't let you kill them.
[grunts]
[choking]
This is Dr. Catherine Durand. Can you hear me?
- [Richard] Where are you? - [Catherine] Another world.
An alternate timeline.
There's a formula that maps
the entanglement entropy of any object.
It can be applied to the black hole.
[gunfire echoes]
Catherine?
[robot limbs whirring]
[banging]
[banging on door]
[banging continues]
- [baby crying] - [speaking in French]
The aliens figured out that black holes are woven
from the fabric of space-time itself.
It's like a giant quantum event.
As space-time fluctuates and bends,
it creates gravitational waves.
It was Bill's journey to the past
that created the black hole.
And the black hole connects the worlds we're in now.
Are people there being affected in the same way?
The black hole is closer to Earth here.
If we spend more than 50 or 60 minutes outside,
our brain shuts down.
[banging continues]
I can hear them.
The door's holding for now.
There might be a way out.
[Celine coos]
[banging continues]
[vent creaking]
[robot limbs whirring]
[metal clangs]
[sensor whirring]
[robot limbs approaching]
[panting]
[breathing heavily]
[speaking in French]
[Celine coos]
[banging continues in distance]
Warfarin. It won't poison his blood, but it'll thin it.
What will it do to them when they transfuse Tom's blood?
If we use enough of it,
it will cause internal bleeding around the organs.
Perfect.
[banging continues]
[Nathan, muffled] Hello?
We know you're here for Emily's brother.
If we give him to you, will you leave?
[Mariam] So, how do we know he is who you say he is?
Leave him outside the door and we'll go.
I don't want to see anyone in the corridor.
[door opens]
[sighs]
[grunts]
[Bill] Hey, Tom.
Hey.
What're you doing?
I'm...
I'm reading about black holes.
Oh.
I think the aliens may be trying to create a miniature one.
Is that bad?
It could be.
[footsteps approaching]
Richard's on the video link.
I made contact with Catherine.
She's alive?
She's in the world that you traveled back from.
She's with her sister. They're trapped in a basement.
I lost contact with her.
Did she say anything else?
Well, she says the black hole is more powerful there.
If you're outside for too long, it causes you to fit and die.
What is it?
I...
I think the aliens...
They're... They're trying to create a microscopic black hole.
What would happen if they succeeded?
The micro black hole emits gravitational waves.
They could entangle with the waves
from the black hole at the edge of the atmosphere.
And what would that do?
The entanglement creates a monopole.
The net magnetic charge
draws the black holes towards each other.
The larger black hole in space
would be pulled into our atmosphere.
The gravitational waves would become much more powerful.
That's how they're gonna kill us.
[water dripping]
[speaking indistinctly]
[Celine fussing]
[shushing]
Hey.
[device whirring]
You killed Hiram.
He thought he could save you.
What were you going to do if you escaped?
Were you going to try and find Tom?
I want my baby to live.
None of us will live.
There's one last thing I need you to do.
I want you to take me to Bill Ward.
[machine whirring and rumbling]
Something's happening.
The power of the gravitational waves is increasing.
It's them.
It's started.
The black hole's drawing closer to us.
[Zoe sighs]
What can we do?
Even if you could find the particle accelerator
and shut it down, it's too late.
It's started a chain reaction.
How long do we have?
I don't know.
[Zoe] Tom.
You should go be with your parents.
Can you get us into a bunker?
No.
Should we get in the underground?
Anywhere underground will protect you.
Go be with your mum and dad.
Tom.
Look after yourself.
You too.
Hi, Dad. It's me.
Listen to me. You need to get out of London.
[sighs]
They have no idea what might happen.
Maybe it's better that way.
Zoe!
[guns firing]
[screams]
[gun firing]
[gunfire continues]
[gun clicking]
[grunts]
[pants]
Is this your girlfriend?
She was just using me.
Do you want me to feel sorry for you?
I'm pregnant.
You're pregnant?
I didn't think it was possible.
Now I want it more than ever.
I'm sorry.
- Step away from her. - Okay.
All right.
[grunting]
- [choking] - [grunting]
All that's happened is because of you.
That's not true.
You infected Emily.
You poisoned her blood.
You're responsible for all our suffering.
My children died because of what you did.
You're the one who sent Sacha and Emily away on a ship.
- To save my people. - As I was trying to save mine.
[scoffs]
You think we're the same?
We are the same.
[gun firing]
You will suffer as we have suffered.
Billions of people are going to die.
How does it feel knowing you're responsible?
For whatever part I've played in this whole fucking thing,
I'm sorry.
But if it was my fault,
why don't you just shoot me and be done with it?
Go on. Kill me.
I'm begging you. Kill me.
[footsteps approaching]
It's too late.
You can't stop it.
There's nothing you can do?
No.
[gun fires]
[panting]
Jesus.
What is that?
[Bill] It's the black hole.
Guys...
[grunts]
Ash!
[Ash breathing heavily]
[Kariem] It's okay.
It's okay.
[call ringing out]
Thank you for holding. Your call is important to us...
Come on, Richard.
[sighs]
Come on, please.
Bill! Bill, I'm here.
Listen, the power of the gravitational waves has nearly doubled.
We don't have long before it starts affecting people.
[Zoe] There must be something we can do.
We have to close the black hole.
How?
I don't know.
Micah's notebook. Where's Micah's notebook?
Adina burnt it. She didn't want you to be able to use it.
Catherine told me she'd figured out
how aliens create black holes to travel through space-time.
So that means she knows how to close it?
I'm not sure. We still haven't been able to contact her.
Where was she when you last spoke to her?
At the Hayward Gallery. They were trapped in the basement.
The aliens were trying to get in there.
Did they get to them, you think?
I don't know.
[beeping]
How bad is it?
Am I gonna die?
I think we might all die.
Jesus.
I need to... I need to call Hayley. Yeah.
Voicemail. Hey!
I...
I want you to know that I love you and little Jack
more than anything, okay?
[breaths raggedly]
You're my whole world.
I'm going to Oxford.
You're gonna try and find Catherine.
You don't even know if she's alive.
It's the last chance we have of stopping them.
Here, go to my room at the halls. Stay there.
What happens to me if you stop it?
I don't know.
You should go.
Tom, you should go with her.
I'm coming with you.
Okay.
Hey.
No, I'll just... I'll slow you down. Go.
Go.
[sighs]
[Ash groans]
I know you're wanted by the police and everything,
but we're still gonna call an ambulance, right?
Are you okay?
Martha's pregnant.
[grunts]
How do you feel about that?
She's an alien.
If you like her, make it work.
Might be your last shot.
I guess it doesn't matter if we're all gonna die anyway.
I'm not gonna let that happen.
You don't know you can stop it.
I'll do whatever I have to.
You need to drive faster.
[car speeds up]
[Catherine humming]
[breathing heavily]
[phone ringing]
- [Johannes] Hmm? - Shh!
I swear I didn't tell anyone I saw you.
Relax. We believe you.
Do you have the calibrations that Catherine used
for the particle accelerator?
They're stored on the server at the lab.
You gotta get us in there.
Why?
Because I want to do what Catherine did.
Are you insane? She's in a coma.
Only in this world.
- What do you mean? - I'll explain it on the way.
Open the door.
You think this glass is bulletproof?
Just open the door.
[beeps]
Give me the card.
Don't go anywhere.
[lock beeps, door opens]
[computer beeping]
[typing]
[machine chimes]
[machine whirring]
Bill.
Okay, then.
If you find Catherine, say hi from me.
Just "hi"?
Tell her I love her.
[sniffs]
I've always loved her.
Good luck.
Bill?
I forgive you.
[sighs] You'll be a great dad.
I know it.
[machine warbling]
[door beeps]
[water dripping]
[chattering indistinctly]
[banging]
[Bill] Hello?
My name is Bill Ward. I'm looking for Catherine Durand.
Bill?
Nathan.
This is so weird.
Is Catherine with you?
Catherine?
There is someone here to see you.
Catherine.
Bill.
[Celine fussing]
How did you get here?
Same as you.
Your friend Johannes, he programmed the collider.
Why are you here?
I need your help. Do you know how to close a black hole?
Maybe.
