Original subtitles

All over the world, humanity reacts to the simple fact that the species that

came before us has woken up. We would speak with him.

We're putting an enormous amount of pressure on one man.

Tissue samples.

Not our enemy.

It'll be the death of the energy industry, of your livelihood.

We'll be sliding into recession.

We cannot hear, or see, or breathe.

So tell me why we should live like this.

For just one day longer.

Mum! Oh, my God.

They're cleaning up the ocean, the plastic, the pollution, all of it.

doing it fast.

All across Manhattan, the sky is raining plastic.

They're declaring war.

Our next meeting will be here.

German's Trench, one of the deepest waterways on the planet. Will you meet

Barkley, at the bottom of the ocean?

Okay.

Let's go, people.

Welcome to Blackport.

We don't have much time, but we've appointed the best naval training

to prep us for the descent.

They'll be doing everything they can to prime us both physically and mentally.

Monitor our stamina, heart rate, and blood pressure.

And help get us used to the water.

We'll be descending to the rendezvous point of the submersible to a depth of 8

,000 meters, five miles down.

Our journey will take two hours and 17 minutes.

The submersible is currently on a launch vessel with warship escorts bound for

the descent point.

On the dive will be the ambassador, myself, Captain Mackey for

myself for science and technology, and...

Our two diplomatic representatives, Mr. Singh.

I'm Robbie.

And Mr. Campbell.

Ted, it's a pleasure.

Have we ever been this deep before?

Small emissions of one or two people. Nothing of that scale.

And I bet they were trained specialists with years of experience. We have days

to prepare for this. Yeah, of course there's a risk.

What we're doing today is unprecedented, but this is the toughest submersible on

the planet.

This is Kate Lethbridge -Stewart to launch vessel.

Captain Gates, how are we doing?

Just finishing final checks.

Pre -launch

checks complete.

Submersible ready for deploy.

Think I'm wrong all the time.

Why did you bring the leak?

That kind of pressure, you'll be crushed to death, pulverized in an instant.

I'll just keep your voice down.

If you do this, you might never come back. Deep sea pressure compresses air

-filled spaces in the body, leading to lung compression and potential... Now,

once we arrive at the descent point, Homo Aqua will transfer us to their

environment.

Well, what about the Descent? Are they helping us with that?

For the Descent, we're on our own.

We're not alone.

We're never alone.

Sorry?

We're a team.

Okay. Yeah.

Transfer by helicopters at 0600.

Indemnity forms need signing and legal have noted you haven't replied to their

emails.

You do need to make sure your will is up to date.

Is it, then?

Do I get a hug before I go?

It might take weeks to clean the roads.

The city's been shut down. You can't go anywhere.

Yeah, well, it's luckier back here, then.

We're at war.

I know. I'm going to sort it.

How?

How are you going to sort anything?

Do you know what they're calling you on TikTok?

Oh, I don't really know.

Tracer.

bootlicker, bleeding heart puppet, too thick to negotiate.

That's not fair.

It doesn't matter, because either way we're screwed.

Either they kill us, or we kill ourselves.

I hate the lot of you.

They're worried sick about you.

Yeah, I know.

I'm sorry, but I promise you I'm going to be fine. No, no, no, no, no. Please,

please, please don't.

Got this?

Okay.

I can do this.

I mean, for God's sake, I nursed mum through cancer, didn't I?

Didn't I?

Bloody hell, if I can get through that, oh, I can get through anything, can't I?

I can't be strong for everyone else, right? Because everyone's counting on

Okay? So, because it's the whole world.

You don't have to be strong for me.

Oh, I'm so scared.

I'm so scared.

Right, that's it.

Okay, now.

Of course you are.

You're going to come back a hero. You know that, right?

This will set us up for life.

Speaking tours, book deals, the works.

Is he going to get a girlfriend out of it? They're going to be queuing up,

All you've got to do is hang in there.

You know, sometimes I can hear my life coach.

Hold the line, Ted.

That's what he'd say in moments like these. Moments of fear, of self -doubt.

Believe in yourself.

Trust in fate and hold the line.

I get struck by lightning dead at 50.

Seriously?

What's in the box?

Diplomatic gifts.

From all nations.

And what are Homo Aqua supposed to do with the globe?

I see the word from Anjaneth, right?

From the depths.

Never like this.

Where are they going to put it, Dad?

Who knows?

Maybe they've got, like, coral mantelpieces.

Aren't you fazed by any of this?

We're going to be fine.

Boot floats.

In the words of a great man, we can be heroes.

Let's save the world.

You have a hatch?

Controls are all units.

We are clear.

Confirm lock.

Captain Gate handing control over to you.

Okay, let's pick it up.

Let's move it out.

Taking you off the ship now. Good luck, everybody.

Good luck to you all.

That's all at this table, sir. Over.

Deployment is go.

Control deck, all readings are stable. We are good to go. Over.

You okay, Ted?

Isn't that terrific?

Yep.

Can be.

On my mark.

In three, two, one.

Mark.

Seven minutes.

Gone dark already.

No sunlight.

Imagine living like this all the time.

Anyway, we're fine, aren't we?

Can I get a yes, Ted?

Yes, Ted.

I've got some team bonding work games, if anyone's interested.

No, thank you.

Who'd you end up here anyway?

There was a diplomatic lottery for the last two seats, and India won. Or

lost, depending how you see it.

There was rumors flying around that the draw was rigged, that most people had

their names removed because they didn't want to go out.

I mean, one way to look at it is we're pioneers.

Like those early astronauts.

Where would we be if they hadn't taken that one giant leap?

What is that?

It's adjusting to the pressure.

Are you sure?

It's okay, Ted.

Just breathe.

I'm breathing. I'm fine.

What do you think we'll get for dinner?

When we're back on the ship tonight, hmm?

Think they'll spoil us? They bloody should.

No.

It'll just be canteen sandwiches again. Tough being a hero.

Is this... Is this water?

This is water.

There is water in here, right beyond the ship. Ted, calm down. It's

condensation. How the hell do you know? Because I read page six of the safety

briefing.

Sorry.

I guess if there was a breach, this thing would implode before we knew about

Can everyone just shut up now, please?

The economy's already tanking. If we start closing shipping lanes, the

could be catastrophic.

Sorry, sir. Kate Lethbridge -Stewart.

Okay. It is a directive of the United Nations that you need to have a voice in

any emergency discussion. Sorry, we started a little early. A lot of people

couldn't make it. Some of the covenants are joining remotely.

With respect, it's a phone call.

I'll catch up. Please, carry on.

The United States relies on maritime trade, and we will defend ourselves

vigorously against any disruption to our network.

The U .S. military is arming itself with sonic weaponry.

Sound cannons are used for crowd control, but we've adapted the

underwater use.

We've identified two shipping lanes we need to protect.

The English Channel, the Panama Canal, the Suez.

Ultra -high -frequency blasts could disable or confuse Homo Aqua, paving the

for traditional weapons, if required.

Sorry, why are we discussing weapons? Our focus is on diplomacy.

And there is an armistice agreement in place now to stop further violence.

Someone's got to be the first to break it. Sir, our focus should be on

diplomacy. That's why six of our diplomats are risking their lives today.

They're buying time.

That's all they're doing. It's a song and dance, smoke and mirrors.

The General's right.

We make decisions.

Here, in this room.

Western Front, the Falklands.

Iraq.

Wars are fought and won at this table.

They think they own the water.

While they were splashing around 300 million years ago, we crawled out of the

water.

And we conquered it.

We built a civilization that depends on our oceans to power our homes, feed our

crops, and keep us alive. Keep you in business?

Sorry, but I agree with Kate.

Their civilization is so ancient and so powerful.

Aren't they a gift?

Couldn't they help solve not just the climate crisis, but so much more?

If... We had them on side.

We're never going to get them on side.

They want us gone.

If they wanted us gone, I think that would have already happened.

If they were gone, we could have access to their technology. Think of it.

Treasure from the ocean floor. This is a diplomatic crisis, not a pirate raid.

It's what the West does best.

Colonize and plunder.

I'm sorry, but I'm 60 % water.

We all are.

Don't tell me we don't own the water.

If Homo Aqua want a war between the land and the sea, we'll take the sea. So

this kind of rhetoric is irresponsible.

If you're trying to keep the peace, you've already failed.

If you're not on side, we might have to reconsider our options.

Diplomatic responsibility can easily be transferred. What do you hear?

A global emergency committee could guide Homo aqua through a peace process that

puts mankind first, not you. Sorry, what does it keep doing in an emergency

meeting? It is not...

Cabinet or agency and his companies at this very moment are still pumping

millions of litres of sewage into our waterways. This process is take time.

don't get me started on General Giselier who leaked confidential information to

the press. I think you need to calm down, love. This is a national security

matter. The fact is we need industry and our allies on side.

We can't do this alone.

What's going to happen down there? Hurry, come on. We've already said we

know. So what if this is a trick and they want hostages?

We didn't take any hostages. Why should they?

Because that's what happens in war.

I promise you, we're going to sort this.

OK, I don't know how we will, but we will. Because my kid is not living

a war.

I never had kids.

If I get out of here, I'm going to call my brother.

We haven't spoken for 20 years.

First thing I'm doing is taking my family out for a meal.

All 19 of us. 19?

Yeah. Yeah. And I'm paying.

It's hot.

This suit.

How deep are we? All right, Ted. Come on. Come on, Ted. Don't think about it.

watched this show where they made a human out of pig parts.

Bones and meat.

And they put it in a diving suit and they...

But tested it to keep see pressure. Mr. Campbell. It just turned to soup in a

split second.

No one wants to hear this. I don't want to be souped.

All right, okay, it's okay. You're okay. Ted, come on. Come on. Look at me. Just

breathe. Just breathe now. Breathe now, please, with me. Okay? Slow and steady.

With me.

Because we're a team, aren't we?

Yeah? Okay.

Turn that off, please.

A few days ago, the situation was dire.

We were staring down the barrel of unprecedented financial and energy

Now it's catastrophic.

We cannot surrender control of this planet.

Look what they did to us in 15 minutes. If they wanted to, they could wipe us

out. You need our looking after their own interests.

It is our moral duty to stop Aquakind however we can.

I know you have a lot on your plate right now. Alison had a test today.

She'll be with her.

I already know you value my opinion.

And maybe my money. The generals have decades of military strategy under their

belts. Let us guide you. Take the pressure off.

When I became Prime Minister, I made a promise to my grandchildren to leave

country better than I found it.

Sir, if we don't win this war, and war is what it is, there will be no

grandchildren.

But we believe there is a way through this.

A new stratagem, just between us.

We're calling it Severance.

I found some instant coffee.

And... biscuits.

I won't ask you what you had to do for those.

Yeah, let's not.

They'll be okay.

But you look exhausted.

I've had six hours of sleep in three days.

This morning I showered in a sink.

sent good people five miles under the ocean and sat through a Coburn meeting

with a rummful of warmongers.

You need a break.

They want to shut you in and out.

And if we lose control, who steps in?

Who decides the future of the human race?

Sorry, so most of us enter in the deepest part of the trench?

Yes.

Get me Captain Gates. I want a situation report AS18.

This is uncharted territory.

They're off the maps now.

This will be the longest night of our lives.

What's that? What happened?

I think we stopped.

Are we on a seabed?

Negative.

This is SU -1 to surface.

Surface, this is SU -1.

Hello?

Is anyone there?

My God.

We're not in here.

But, Captain, what's happening?

We're moving at 12 knots.

18 knots.

These readings don't make sense.

That's not possible. 13 knots.

Something's taking control.

How are they moving so far?

Captain? What? Are they being dragged?

I think so. They're descending twice as fast.

Steve, how's the pressure?

Pressure's holding.

We've lost comms. Ping the transponder. No response.

Okay, do you feel that? Do you feel that wave descending?

Why is there no radio contact?

Oxygen's normal. The cables are functioning. We're just cut off.

The pressure on the hull is 1 ,200 HPA.

Is that good or bad?

That's like sea level.

That's the pressure on land, except we're five miles down.

Five miles.

What? Are we inside something?

The whole system's gone down.

Helmets down, everyone. Backers are kicking any second.

This is a trap. They're going to kill us. Wait, they test. Shut up.

Well, that's it.

That's backup.

There's something at the hatch.

It's them!

Is that cave?

I don't know. Wait there.

It's alive.

Temperature is 21 degrees Celsius, which is impossible.

The atmosphere is breathable, not just breathable, it's perfect.

This place is incredible.

You can come out now, be careful.

There's a drop.

It's some kind of membrane.

Billions of tons of water behind this.

One tear in that membrane.

Watch your step.

The ground's uneven.

If this is the ground.

What the hell was that?

Decontamination. Everyone okay?

What is this place?

It's like nothing in the world.

It's like hell.

Welcome.

Where exactly are we?

Deeper than any human has ever been.

You can remove your apparator.

No, wait.

This environment has been prepared for you.

Will you trust me, Barclay?

It's okay.

The roof's leaking!

There is no roof.

What? But you are safe.

I prefer to keep this known.

As you wish.

It's fatigue.

You're running on empty.

All this pressure, taking a toll.

Pretty soon you're going to be of no use to anyone. I feel fine.

After 48 hours, the brain and the body start to shut down.

I've seen it happen, and I'm watching it happen to you.

If I reported you, you'd be escorted from the building.

Except you wouldn't do that.

The delicate... are miles beneath the surface in radio silence for hours.

There's nothing else you can do right now.

But soon as they're back, we need you on form, rested, and ready for whatever

comes next.

You're amazing.

But you're not invincible.

I died. Take you home to rent, or I report you.

My apartment is a fully equipped comms hub. I'll work from there.

So, how is it light down here?

Well, many of the organisms are bioluminescent.

Bacteria, plankton, species of fish.

So are we inside an organism?

I have no idea.

This is impossible.

Your world of steel and glass and sunlight is equally impossible to us.

And is this where you live?

No.

We are nomads.

All of the oceans and waterways are our home.

They are curious.

That is all.

So do you all live here, together, like all the species?

There are the fish.

There are the titans.

The dolphin and us.

Huh. That's, uh, it's like a hierarchy then, like a class system.

There are degrees of intellect.

Do not assume we think as one.

Oh.

Oh.

Oh, sorry, sorry.

I, uh, I just, uh, this is a lot.

Here.

Hold on to me. Come on. Come on.

Keep moving. Keep moving.

Come on.

Hang on. Where are the others?

Have the walls moved?

It's just you and me.

Is that weird?

I understand.

You're so warm.

And rough.

What do you feel?

Strength.

And beauty.

I don't know why you chose me for any of this.

The tides have drawn us together.

The undercurrent pulling us closer.

If you calm your mind, you'll feel their power.

But your thoughts are noisy.

Can you read them?

Human emotions are so loud.

We cannot help.

But listen.

Your heart is racing.

Yeah, I don't want to mess this up.

Billions of people are counting on us.

You have good intentions.

We could make a difference, you and I.

End the conflict between our species.

Before it's too late.

Yeah.

Berkeley!

We started last year.

Are you alright?

Yeah. We are assembled.

Oh, my God.

Do not be afraid.

This is hard help for you.

Make it go.

Welcome to our domain.

They're down there, on their own, with no support.

Do you think one day we won't need to keep us a secret anymore?

I don't know.

I'm sick of hiding it.

Pretending. Worrying about being transferred to God knows where. Alaska?

You find it so easy.

The future of the human race pivots on what happens tonight. We don't matter.

How can you be thinking about us?

I think about us all the time.

Can't you not be commander -in -chief? Just for a few hours.

I don't know how.

You... Shirley, hi. Any news from the

delegate? No. All quiet.

So I ran some intel on the people in that Cobra meeting.

Thanks. I think I found something.

A repeated word in diplomatic communications.

Does the word Severance mean anything to you?

No. It's never appeared before.

Now it's been used 14 times in the last two days.

The coldy message is going back and forth.

Severance. Severance. Severance.

Kate?

I love you.

I love

you.

You. You.

You.
