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

Let's save the world.

This place is incredible.

I thought I'd know you. I'm not going to know you. I've known you forever.

The tide have drawn us together.

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

kind of rhetoric is irresponsible.

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

Welcome to our domain.

The word severance may not seem to you.

Coldy Matthews going back and forth.

Your rule is lost.

Thank you.

Ground team, stand down building, cover red.

Target building opposite, India House.

Estimate floor 35.

Squad 3, stand down building, Squad 4, India House.

Emergency comes from the diplomatic zone. We have an event. What does that

Platonic pulse.

What does that mean?

Integrity lost.

Jane, please, what does that mean?

They're dead.

All comms through me, Register. Shirley Ann Bingham now in command.

Options 1 to 5 schematics installed.

All stations on red alert.

Tell me, what do we know?

Got them sighted.

Shirley, do we know who he is?

Apologies, ma 'am, we don't know.

And I'm sorry, but we have a major incident in progress.

And we're getting news from military sources.

I'm sorry, this just coming in to us at 5am GMT, but it's just been confirmed

that there has been an underwater explosion at the site of the diplomatic

meeting. It's assumed that all human diplomats have perished and their

efforts have failed.

This represents a major escalation in the war between Homo Aqua and mankind.

An Homo Aqua ambassador has issued a statement claiming responsibility for

death of the H2O diplomat.

What? This is a warning to the human race.

Your diplomats are dead.

Their blood and marrow now feed our children.

The same fate will befall anyone who dares to enter our waters.

The time for diplomacy is over.

Our borders are defended and forbidden.

The water of the world will never be yours again.

Where is this from? Is Steve, is that real?

Could be a deepfake.

Then find out.

We have a visual on the target.

It wasn't Saul.

I swear to you, I'm a witness.

The device was exploded by Ted Campbell.

Theodore? Campbell.

Okay? He was...

They all died.

They were crushed.

Right in front of me.

One second flat they were gone.

Can I ask?

How old was the man?

28.

If it's any consolation, it must have been instantaneous.

No, no, no, I knew.

That second... I'm sorry, they knew.

OK. You told your family you're safe, and the most important thing now is for

you to get back here.

Thank you for being in touch with my dad.

You shouldn't be here.

Mr Pierre Dupont, there is one fundamental question.

I'm not sure I did.

You were lucky.

That was a very long night.

Yeah.

We lost, um... We lost many good people.

Did you survive because of her?

Yeah, she... Yeah, she held me. I don't know how or why.

You do know that broadcast is a fake, right? I mean, for God's sake.

She's here with us. You took her on board. She could have escaped. She had

whole ocean, but she didn't. She stayed with me.

We'll do that on dry land.

All right. Well, let me, let me talk to her. I'm afraid that's not possible.

You have to remember.

Five people are dead, and that happened on Aquakind territory.

In the eyes of the world, she's taken responsibility.

And the names of the diplomats killed in the undersea explosion have now been

confirmed. These include unit staff captain Louise Mackey.

I don't suppose it's ever going to be a body.

Don't think so.

That sketch pad.

She was always drawing.

Why should I take this?

Sergeant Lake, you can pass it on.

Louise's mother lives in Kirkcaldy. I'll take them.

I'll visit her mother in person.

In Kirkcaldy?

When are you going to find time for that? She died under my instructions.

I will find the time.

Give us ten minutes.

Any word from Undersea?

It's gone quiet.

And you're going to need a personal guard.

I'm not going to be followed night and day.

Kate, someone tried to kill you, not Christopher.

Oh, we've identified the assassin.

Here he is.

Miklos Konstantinos.

Born in Athens, 1985, relieved of command from the Hellenic Army, 2010.

Crops up the mercenary with pro -Gaddafi forces in 2011.

Gone for hire.

But one of the best. He's been invisible since 2019.

If there's any connection to Libya, it's possible that he would...

So the question is the

question is

Who hired him?

But this is nothing to do with us. Please tell me this is absolutely

do with us. We've never been so stupid.

If I wanted Kate Lethbridge Stewart dead, I could do it in a blink of an

You will watch your tongue, sir.

That woman serves this world in ways we can never imagine.

But still, we might be in trouble.

We have links suggesting this man was employed by the Institute of Las

The same people who sent Ted Campbell on his mission.

Ted Campbell had stage four pancreatic cancer. Happy to give his life for the

Institute. But who are the Institute?

A private think tank founded and supported by billionaires. And their

are clear. It's a great replacement theory.

Terrified of Omoakwa replacing mankind.

But they are literally nothing to do with us. That explosion, there is no

connection to us, not in any way, shape or form.

In there.

I can close the institute, going in with force within two hours. Hand them over

to unit, case closed.

Lethbridge -Stewart is safe.

But one problem remains.

Campbell was an associate of Sir Keith Spears, your greatest donor and your

good friend. Yeah, but he's not part of anything.

He's an idiot, but the man's a clown!

No, but the problem is he invested £100 ,000 in the latter Clementi Institute in

2015.

I don't imagine we're connected to the explosion, not for a single second. It's

too much of a coward.

But the authorities will find the link, and if they investigate Sir Keith...

He's bolt of severance.

He automatically creates a link back to us.

Oh, my God.

Exactly.

We're connected.

It's, um, unlucky.

Sir Keith Spears is a major investor in the privatized water companies. A lot of

people blame the water companies for provoking the ocean.

So, Prime Minister, all I need to know is, do you give me permission to deal

with this?

With no connection to me.

With no connection to you.

Oh.

They'll look after her.

Where are they taking her?

Unit Tower.

She'll be safe.

They said that to us.

Look at you, boss.

Come on, show some respect.

Mr. Ambassador, I was saying to the boys, two weeks ago, he was sitting in

office, signing off my overtime.

Now, you're on TV.

I said to the boys, I hope he's getting paid.

Yeah, no, I'm good. I'm good.

Yeah, I'm okay. You know.

You sure you're all right, though, boss?

Because I was kind of mad. They said you was right at the bottom of the tea.

It was, um... It was crazy, yeah.

And she's in there?

The fish?

Yeah.

She's sushi, mate.

It's, uh, kind of offensive, mate.

Oh, no, but come on.

She murdered all those people. She's going straight to the lab and she's

to be sliced and diced.

I'm going to get back to work, actually.

It's night about now.

Give me the keys, I'll move, all right?

No, I've got this.

No, I know you have.

But I can do it.

Just give me the key, yeah?

Are they flying me on this? Yeah, but who clears the signatures, that would be

me.

Come on, who's involved?

He told me to give him the key.

Barclay, what are you doing?

Barclay, stop it, get out of there!

Hey, come on, man. Don't get me in trouble. Come on.

Get down. Get off the truck.

Barclay, this is not the solution.

Now step down and I promise you we can talk this through.

We can talk with Salt, okay?

Just look around.

There's no way you're going to get through us.

Like you're going to shoot me in front of the press?

Like you're going to drive right through them?

Yeah.

They said I was going full.

Go down to the river.

Spread out. Get me boats in the water now.

Sorry, Mom, we've got a problem.

Barclay, bloody Piers.

Stupid name, DuPont.

Breaking news now with reports that the only survivors of the H2O tragedy are on

the run.

Oh, my God, he jumped.

He actually jumped. Why did he do that?

Is Barclay DuPont a collaborator? It certainly looks that way.

The Americans have taken down the institute so it looks slightly safe.

And if you don't stop work, I'm going to phone your daughter and get her to

carry you out.

She's in Dubai.

Did she know about you and Christopher?

I thought no one did.

So what is where we were all very happy for you?

I'm so sorry.

That's enough.

Where will you go?

Oh, hotel.

I just need to get out.

I'm sorry, ma 'am.

Morris was asking if we should look into this.

Oh, it's a... It's an act of terrorism. That's the police. Nothing to do with

us.

No. Wait.

Investigate. Yes, ma 'am.

And with that, good night.

There's the trigger, the Thames barrier. We've got lifeforms, ma 'am. What

lifeforms? Incoming straight from the channel. Good evening, everyone. Nice to

be back.

Nine lifeforms in total heading in our direction.

We call delegates, staff and security to the Empress Hall. Priority one standby.

Everyone on maximum alert.

But who's the ambassador?

Sir Jonathan is 40 minutes away. I'm trying, Admiral Tavares, but there's no

reply. I'll do it.

You're exhausted. You aren't at a time to stop.

Are you saying I'm unfit for duty?

Yes. Noted.

Homo aquiform and one life on this brand new.

Homo amphibia male presenting, body muscle index 22 .4, blood pressure,

rate both strong, cortisol and adrenaline.

He's a warrior.

My name is Kate Lethbridge -Stewart, Commander -in -Chief of the Unified

Intelligence Task Force, and I stand before you tonight on behalf of the

of the Earth with a desire... Why are you all insane?

Right. You came to our world and killed yourselves

to make everything that is happening worse.

Why in the name of the waters would you do that?

Why, you beasts of such insanity?

Page five, paragraph two?

No, go to page six. Try page 22 from the top.

I, uh... Oh, here we go.

She's gone rogue.

Even better.

I can only say that if you study the culture of this world...

The thousands of years of fiction and stories and science and philosophy, and

not one of us can answer your question. We are a species whose intelligence is

running so fast, it's a thousand years ahead of our emotions, and that causes

to stumble and fall time and time again.

And I'm sorry.

I accept that response.

And I'm addressing Ambassador... My name is a wave on the current through the

coral and the sand.

But you might call me Tide.

Ambassador Tide.

Now, where is she?

Who? Ambassador Tholt.

I can't say.

She is your prisoner.

Technically.

You must understand.

I ask this not in a bid for her freedom.

Then what do you want? She chose to save a human life and left Aquakind to die.

We were murdered while she helped him.

Salt has transgressed against the laws of our nature and the fate she must

suffer exists under the sea, not upon the land.

Now I demand to know, where is she?

You lost her.

With his help. What is it that binds these two together?

We are trying to find them.

But the problem is, Ambassador, if you intend to punish her, I can't hand

her over.

Then yet again, we are at war.

You're something of a warrior yourself, and yet full of despair.

Despair that is new.

I lost someone.

That is good.

You will strive to prevent losses to come.

Because we are tired of waiting.

And if we have to escalate the war between us, then we will.

What does that mean?

You have met salt.

You have met tide.

Beware our third ambassador.

Run.

Because water is not confined to the seas. Water is in the air.

And we can make a weapon of that water to create... Rust.

Eating at your cities.

And cars.

And missiles.

Until it brings your civilization down. From rust.

Into dust.

These negotiations are over.

You will find salt.

You will return her to us. You will advance the plans to change your world.

Within five years. That's impossible.

Make it possible.

One more thing.

Yes?

Change the name.

The name of what?

Uh... Too Dry.

Oh, we got owned.

We got rocketed.

We need to find thought.

What? We've tested the samples, but we've never tried severance on an adult

amphibian. But they're the leaders.

They're the prime species.

If we can use salt, I can end this war.

I reckon I got distantry.

An E. coli and probably leprosy, because that river was filthy.

My neck.

Oh, it feels like it's been snapped.

Oi, oi, oi, what are you doing? What are you doing?

Glass is fascinating.

Can you imagine when we woke and saw this world with all its structures?

All right, well, just mind your feet. I'm going to get a cut.

You're always so scared.

Yeah, I am.

You won't die.

I cleaned you of protozoa.

I took your breath.

And my gills filtered the dirt.

That's amazing.

You do know you saved my life down there.

When you kissed me. Is that what you call a kiss?

The pressure of two orifices sealed together in order to preserve a

shield for the maintenance of your lung capacity.

Oh, no, no. Don't start talking sexy.

It is a good neck.

Mm -hmm.

Strong. Yep, yep.

You should put that gale form in the melee.

After all, you already have very good fins.

Is that a joke? That was a... That was a joke.

I mean, well, we're just on the run.

People from both our worlds chasing us, and she developed this as a human.

I am liberated.

Come on, come on, we're supposed to be hiding.

It's a alienation, do you not?

No.

What's it like under the water? Do you have family?

We meet at random and spawn in our thousands.

But we're capable of more.

We have happiness.

We have anger. We have love.

We have... Oh, we have the water, Barclay.

We live in the water, of the water, for the water, with so much power.

We must look like apes to you.

I mean, we are apes, clodding about on the land like, um... Well, like apes.

You've been to the stars.

You've mapped entire galaxies in the sky.

We never did that.

Maybe we were too proud of the water.

Maybe it weighed us down.

If you went back, what would happen?

What would they do to you, Aquacon?

I would swim alone.

Right, but not, like, executed or... Worse than that.

I would swim alone.

Forever, in the vastness.

Like a shark?

A shark.

Has a soul that is dead.

I would live with a dead soul.

I think you understand that.

There's a loneliness in you.

Yeah.

You people are so constructed.

You apply fabric to your bodies.

Leather on your feet.

And you walk in the air with such pomposity.

But underneath, you burn with animal heat.

Your creatures of fire and doubt and envy and fear and

laughter and lust.

We watched you for so long under the sea.

We could feel you burning on the land.

I think we would have always found you because your heat is

irresistible.

Is that fear?

What? Your heartbeat.

Racing.

That's not fair, exactly.

Your heart is clamoring now.

Yeah, yeah. Of course my heart.

And my head.

Because we were going to die.

Eight kilometers down.

And I've got this ringing noise in my ears and this pain, and when you created

that hyperbaric thing, everything just was so much better when you pressed your

lips against mine.

I find you unique.

I really thought your skin was going to be cold. I can regulate my body for you.

Yeah, I'm sort of...

Regulating my body for you to... So I see.

Is that okay?

It's wonderful.

The name I chose was appropriate because you taste of salt.

Well, you taste of, um... I don't know.

Horizons.

Are they searching for us?

The whole city's on red alert, so yeah, I reckon they're looking for you.

You work with the army.

Is there no one you can trust?

Oh, I don't know.

My lot's tough.

They're beyond the army. They're beyond the police. They're, like, at the top,

and if you disobey the rules, you vanish.

The woman in charge.

Yeah, that's Kate Lethbridge -Stewart.

She's a good soul.

Yeah.

How do you get to her?

You don't have to stay with me.

You could just... swim away.

The moment I enter the water, they will know.

They will find me.

And they will punish.

Okay, uh, options.

So, we need to... get out of the city.

Right? Because everyone's a red alert, and it's, like, lawless out there.

public enemy number one. So am I. We're going to get shot in the street, so we

need to find her.

I mean, hang on a minute. We could go north Wales, because I know some people

there. And I know this guy there, and he's done, like, five years in a regular

army. I mean, he hired us. He's off grid. He's nuts.

But at least if we can get there, we can work out what we can do next. And then,

then, then, then, we can get a message to Kate, because we can talk to her

We can try.

I can live in the north of Wales.

Oh. Got you. Yeah, it's got lakes and waterfalls. It's beautiful. I could live

in lakes and waterfalls.

I could be the witch of the waterfall.

Yeah, you could be the witch of the waterfall. I just... oh. Live with me in

waterfall.

But how would we get there?

Both the land and the sea are closed to us. Yeah, my phone's probably tapped.

The minute I make a call, they're going to know where we are. I just...

Did I mention to you that it's lawless out there?

Come on, just calm down. It's all going to be okay. I just want you fine.

Mate, OK, stop moving, stop trying to run away.

Or... She will eat you alive, mate. She will eat you like fate, mate. And that

right monster... There you are.

Oh, hang on.

What's this?

Here you go. What have you got on that face? Look, smile for the camera.

Thank you for your services to King and Country. If you tell anyone about this,

she will find you at midnight. She'll eat you. Go on then, off you go.

We're a good team. Shall I hiss again?

Uh, no, we're done.

So, they are definitely going to be monitoring my family phone, but Kirby

got a second phone, in secret, because Barbara, that's my ex -scientist, I'm

reading Kirby's text, says they're not old enough, which drives Kirby mad, so I

did a dab thing on the slide, just to buy favors, and I got Kirby a second

Okay.

Hello? Kirby's me.

Oh, my God.

Don't say my name.

I'm fine. I'm fine. I am so fine. I am okay, but I haven't got much battery on

this phone.

Where are you?

Listen, we've got to be really careful, love.

Okay, because they might have wired the room. They will definitely have wired

the room, so we've got to be so careful. I just need to speak to Mum.

She's asleep.

Okay, just tell her to call me back on this number, but just tell her to call

from the bathroom.

OK, just tell her, do not talk in public. Have you got that, Kirby?

Are you with her?

I am, and it's good.

I swear, I... I love you, Kirby. I love you so much.

Please.

Hey, love.

What is it?

Are you OK?

So, I need to borrow the car.

But I promise you, you'll get it back. I mean, you might not get it back.

I'm straight away, but you will definitely get it back. I just need to

of the city.

And you're with Salt?

Yeah, I'm sure I need to protect her. Trust me.

Please, it'll all make sense. Now, listen, they can't stop you leaving the

hotel, but you will need a permit to drive across the city in the car at

So if you go to my stuff, there's a little leather folder with, like, a zip

it. Do you know what I mean?

I've got it.

You've got it, right. So in there is a permit.

It's like a white card. It's got red around the edges. It's got a U in the

middle of it. If you just... Put that in the windscreen. That will just get you

through anyway.

Um, but where do you want me to meet you?

Well, listen, most of the roads will be closed off, but you can get through

Festival Bridge. Is that good in, like, 30 minutes? I mean, we'll be coming from

the south side.

You and her?

Look, I promise you, I swear, she's on our side.

Oh, for God's sake. It's Barclay, ma 'am. It bloody would be.

One hour to speak. Thank you, Mr. DuPont. Now what have we got? He made

with his family.

Rendezvous, Festival Bridge, 20 minutes. Captain Hannigan is taking us on from

the north. That's less than a kilometre from here. You know Barclay. He trusts

you. Go.

We've got Captain Kamal Owens and Sadie. She's moving in to give us coverage

from the south.

And this is Barclay and Salt.

Barclay and Salt, ma 'am.

SC -18XT, grid 44556.

You're full authority, jet medium 50.

Move, move, move!

Mom,

I've got confirmation.

Not now. The dog's confession is a deep fake, just like we thought.

It's coded. Las Clemente.

She never said those things.

Look, the video is fake.

She's innocent.

Careful. What have you got?

I'm sorry, Control.

I've got nothing for the south.

Well, we had Captain Kamalo covering the south approach.

Where's Captain Kamalo?

Not getting a reply. Everything's on quiet south of the river.

What do you mean, quiet?

Captain Kamalo, can you report?

Captain... Lock him up. Get him out of here.

Target sighted and Captain Kamalo retained.

Hold your positions.

Markley, run!

It's a trap!

Run! Go, go, go!

We've got them! Go, go, go!

What the hell are they? General Gunsberg.

He's intercepted our comms.

General, this is a unit operation.

You will withdraw.

Complain to Geneva. We have a war criminal on British soil.

General Gunsberg, we have proof. Sort of not a criminal.

We'll have to examine that proof. In the morning, right now, we have a murderer

in the loop.

Barkley, stay where you are!

Both of you, do not move!

You will both walk towards us.

You are prisoners of the British army. You will surrender to us.

General, you do not command British troops.

Whitehall has given me authority.

We have a civilian on the bridge.

Private

Collins to

Sergeant Abrams. We don't actually need her alive.

Her body is all we need.

I can't let you do this.

Unit troop, target soldiers, North Acton, grid 49.

What?

Saw none!

Go to the river!

Go to the river!

Open fire at my command. On my command, fire at will. Those are British soldiers

on British soil. You wouldn't dare.

You'll wait a long time, General, till I get away. Hey, don't!

On my command.
