0:00:02 > 0:00:05'All Nektons report to the bridge. Priority one.'
0:00:07 > 0:00:10- What is it?- A distress call from the tiny resort island of Tartaruga.
0:00:10 > 0:00:12It's about to be hit by a tsunami.
0:00:12 > 0:00:15We'll never reach them in time.
0:00:21 > 0:00:24Ah! What in the name of...?
0:00:24 > 0:00:26Get to the boat!
0:00:31 > 0:00:33Oh, no. It's too late.
0:00:39 > 0:00:40Huh?
0:00:42 > 0:00:43What happened to the wave?
0:00:45 > 0:00:48It's like it went through us.
0:00:49 > 0:00:53- Intriguing.- Waves just don't go through islands.
0:00:53 > 0:00:56I know. And I realise this may not be of any interest to you...
0:00:56 > 0:01:00I mean, technically, nothing actually happened.
0:01:00 > 0:01:04Are you kidding? Your entire island was completely not hit by a tsunami.
0:01:04 > 0:01:06That's totally worth investigating.
0:01:08 > 0:01:12Nekton family, set sail!
0:01:15 > 0:01:16Huh?
0:01:17 > 0:01:19Is this something we're doing now, Ant?
0:01:19 > 0:01:23You say a catchphrase and we just leap into action without any discussion?
0:01:23 > 0:01:24Come on, Fontaine.
0:01:24 > 0:01:26You know we're going to check this one out.
0:01:26 > 0:01:30Governor, we're coming to inspect your unsinkable island.
0:01:30 > 0:01:31Yes!
0:01:33 > 0:01:35My family are explorers.
0:01:35 > 0:01:36We have been for generations.
0:01:36 > 0:01:38While others look up to the stars,
0:01:38 > 0:01:40we know there are an infinite number of things
0:01:40 > 0:01:42that shine in the darkness below.
0:01:42 > 0:01:46There are things lurking in the seas that long ago vanished into myth.
0:01:46 > 0:01:50My family are explorers.
0:01:50 > 0:01:53And we explore... the deep.
0:02:02 > 0:02:04It must have gone over the wave.
0:02:04 > 0:02:07How could an island go over a wave?
0:02:07 > 0:02:11Well, it didn't go under it, it didn't go through,
0:02:11 > 0:02:13so what are the possibilities left?
0:02:13 > 0:02:15According to the Chronicle of the Deep,
0:02:15 > 0:02:19the final piece of the Ephemychron is hidden on a moving island.
0:02:19 > 0:02:22We're not the only ones with this knowledge, Nereus.
0:02:22 > 0:02:25You're right, Tethis. Proteus will be drawn to this.
0:02:25 > 0:02:29He already holds the other two pieces of the Ephemychron.
0:02:29 > 0:02:32If he were to get his hands on the final piece...
0:02:32 > 0:02:36Then he can do the unthinkable and everything we've guarded against
0:02:36 > 0:02:39for thousands of years will be threatened.
0:02:39 > 0:02:44If he can find Lemuria, then he can free the Terror.
0:02:44 > 0:02:46And use it to control the world.
0:02:46 > 0:02:48Or destroy it.
0:02:48 > 0:02:52Right, well, I suppose I should go make sure that doesn't happen.
0:02:55 > 0:02:56- Um...- What is it?
0:02:56 > 0:02:58We should have reached the island of Tartaruga,
0:02:58 > 0:03:00but it isn't here.
0:03:00 > 0:03:02- What do you mean?- Look.
0:03:02 > 0:03:04This is a satellite map.
0:03:04 > 0:03:05We're right here.
0:03:05 > 0:03:08- The island isn't.- Ant, take a look.
0:03:08 > 0:03:10Up periscope.
0:03:14 > 0:03:17Yeah. It's definitely not up there.
0:03:17 > 0:03:19Whole islands don't just go missing.
0:03:19 > 0:03:21I'm telling you, it's not up...
0:03:21 > 0:03:24- Ahh!- Ant, what is it?
0:03:24 > 0:03:26- An eye!- An is-land?
0:03:26 > 0:03:28No! There's a giant eye.
0:03:30 > 0:03:35- Huh? - What is it, Dad?
0:03:35 > 0:03:36Hello!
0:03:36 > 0:03:37WILL CHUCKLES
0:03:44 > 0:03:45Mr Nereus, a whole island is gone.
0:03:45 > 0:03:47- I know.- Do you know where?
0:03:49 > 0:03:51Well, let's take a look, shall we?
0:03:53 > 0:03:55A-ha!
0:03:55 > 0:03:56Look.
0:03:57 > 0:04:01But if that's Tartaruga, it's miles away from where it's supposed to be.
0:04:01 > 0:04:03It's moved.
0:04:03 > 0:04:05It hasn't moved.
0:04:05 > 0:04:07The maps are wrong or something.
0:04:07 > 0:04:10Either way, it must be the island.
0:04:10 > 0:04:12Nekton family, set sail!
0:04:15 > 0:04:19I think this is something that should catch on.
0:04:19 > 0:04:21We can't take the Arronax any closer.
0:04:21 > 0:04:22The shallows will extend too far.
0:04:22 > 0:04:25Solar skis ready to fire?
0:04:25 > 0:04:28- Fire?- You're coming with me, Nereus.
0:04:28 > 0:04:30It would be nice to see you surprised for once.
0:04:33 > 0:04:36Firing in three, two...
0:04:36 > 0:04:40Hold on to your beard, old man. One. Fire.
0:04:49 > 0:04:51Keiko, do you remember any mention of Tartaruga
0:04:51 > 0:04:53having a large sea cave?
0:04:53 > 0:04:56- No.- So what's that?
0:04:56 > 0:05:00Wow. Can we see what's inside?
0:05:00 > 0:05:02Not until after we talk to the governor.
0:05:17 > 0:05:18Nektons!
0:05:18 > 0:05:19Sorry we're a bit late.
0:05:19 > 0:05:21You've moved.
0:05:21 > 0:05:23- We've what?- It's true.
0:05:23 > 0:05:26Your island is not where it's supposed to be.
0:05:26 > 0:05:28But that's impossible.
0:05:28 > 0:05:31- Isn't it?- Governor,
0:05:31 > 0:05:35I don't remember any mention of Tartaruga having a large sea cave.
0:05:35 > 0:05:38Tartaruga doesn't have a large sea cave.
0:05:38 > 0:05:41We're going to explore the cave, aren't we?
0:05:41 > 0:05:44Yes! Spelunking. I love spelunking.
0:05:44 > 0:05:48No. You don't love spelunking. You don't love exploring caves.
0:05:48 > 0:05:50You just love saying the word spelunking.
0:05:50 > 0:05:53I'll go back to the Arronax and get the spelunking gear
0:05:53 > 0:05:56- so that we can spelunk.- Hmm!
0:05:56 > 0:05:59Spe-lunking!
0:06:01 > 0:06:04- It IS a good word.- Ohhh!
0:06:04 > 0:06:08Now I think you should come and take a look at something, Governor.
0:06:17 > 0:06:20You're saying you've never seen this before.
0:06:20 > 0:06:24No. I think I'd remember this.
0:06:24 > 0:06:26If this has never been seen before,
0:06:26 > 0:06:30the opening to this cave must have been exposed after the wave came.
0:06:33 > 0:06:36It's as if the whole island has risen.
0:06:36 > 0:06:37Extraordinary.
0:06:43 > 0:06:45Ooh! What's that?
0:06:47 > 0:06:49It's old Acadian.
0:06:49 > 0:06:53This language, we're talking about 4,000 years old.
0:06:53 > 0:06:56But there's no way the Acadian empire
0:06:56 > 0:06:58made it all the way to this island
0:06:58 > 0:07:00on the other side of the world.
0:07:00 > 0:07:02Which means...
0:07:02 > 0:07:03This island came to them.
0:07:07 > 0:07:09Oh.
0:07:10 > 0:07:12The island moved from the Mediterranean Sea
0:07:12 > 0:07:14to the north Atlantic Ocean?
0:07:14 > 0:07:16The island has moved recently.
0:07:16 > 0:07:20- We know that.- If these vast caves run through the entire island,
0:07:20 > 0:07:21it could be hollow and light.
0:07:21 > 0:07:24It could be floating.
0:07:24 > 0:07:28Maybe it was fixed to an underwater atoll and the tsunami dislodged it.
0:07:28 > 0:07:30That's possible.
0:07:30 > 0:07:32I think we'd better get back up there
0:07:32 > 0:07:34and let your resort know the island may be unstable.
0:07:34 > 0:07:36I want to take a closer look at your island from underwater.
0:07:36 > 0:07:40- But I'll need the Rogue. - I'll come with you, William.
0:07:40 > 0:07:41I may have a theory on all this.
0:07:43 > 0:07:46OK. You two keep exploring the caves,
0:07:46 > 0:07:50but keep your communicators and homing beacons on at all times.
0:07:53 > 0:07:54Be safe. We'll see you soon.
0:07:57 > 0:08:00Why can't I have a catchphrase?
0:08:00 > 0:08:02It's not how real life works.
0:08:02 > 0:08:05You can't just yell "set sail" and expect everyone to leap into action.
0:08:05 > 0:08:09Well, every adventure movie I've ever seen proves that wrong.
0:08:09 > 0:08:11Ant, movies aren't real life.
0:08:11 > 0:08:13I refuse to believe that.
0:08:19 > 0:08:22- Um... Ant?- What?
0:08:22 > 0:08:24Someone else is spelunking in here.
0:08:27 > 0:08:30- Hmmm.- Hello?
0:08:33 > 0:08:35Hello, Antaeus.
0:08:35 > 0:08:38THEY YELL
0:08:38 > 0:08:41- Proteus!- I should have known to expect you.
0:08:41 > 0:08:43You are no doubt here for the same reason as I.
0:08:45 > 0:08:48- Spelunking?- What?
0:08:48 > 0:08:51I'm here to spelunk. Is that why you're here too?
0:08:51 > 0:08:53Are you a sinister, traitorous, evil villain,
0:08:53 > 0:08:55AND a spelunking enthusiast?
0:08:55 > 0:08:58Do you know what he's talking about?
0:08:58 > 0:09:00- Not often.- Do not try to fool me.
0:09:00 > 0:09:05I know you are here for the final piece of the Ephemychron.
0:09:05 > 0:09:08You will not find it before me.
0:09:08 > 0:09:11Wait, the other piece of the Ephemychron is here?
0:09:11 > 0:09:13And I will make it whole.
0:09:13 > 0:09:15ROCKS CRACK
0:09:17 > 0:09:19What's happening?
0:09:19 > 0:09:21The island! It's sinking.
0:09:21 > 0:09:24The kids! Ant, Fontaine, do you read?
0:09:24 > 0:09:26Come in.
0:09:28 > 0:09:34- No! Ant!- Fontaine! No!
0:09:34 > 0:09:36Help me! We can secure this to the...
0:09:36 > 0:09:41No, I seek something far more valuable than your sister.
0:09:41 > 0:09:42You...
0:09:45 > 0:09:48Jeffrey, fetch!
0:10:05 > 0:10:07Just one more.
0:10:07 > 0:10:10You're in here somewhere.
0:10:22 > 0:10:24Why aren't they responding?
0:10:24 > 0:10:27- Governor, evacuate the resort. - Of course.
0:10:30 > 0:10:35- Incredible.- The entire island is floating after all.
0:10:35 > 0:10:37Yes, well, by the looks of it, not for long.
0:10:37 > 0:10:39Keiko, the island is sinking.
0:10:39 > 0:10:43I know. But the kids are still inside the cave.
0:10:43 > 0:10:47The entrance has sunk. I can't get to them, Will.
0:10:47 > 0:10:48We're coming.
0:10:50 > 0:10:53Fontaine, it's time to wake up.
0:10:53 > 0:10:54Please.
0:10:55 > 0:10:58Fontaine, if you don't wake up right now,
0:10:58 > 0:11:00I'm going to have to give your mouth to mouth
0:11:00 > 0:11:02and neither one of us want that.
0:11:08 > 0:11:10Ow! You head-butted me!
0:11:10 > 0:11:12You can't just go around
0:11:12 > 0:11:14whacking your abnormally large head into mine.
0:11:14 > 0:11:17- Especially after I save your life. - You saved my life?
0:11:17 > 0:11:19Don't try to change the subject.
0:11:19 > 0:11:22We were talking about how your abnormally large head...
0:11:22 > 0:11:24Thank you.
0:11:24 > 0:11:28It's OK... Weapon head.
0:11:28 > 0:11:32Hey, if you're doing unusually affectionate displays of gratitude,
0:11:32 > 0:11:34I should tell you that I had help.
0:11:34 > 0:11:37- Jeffrey...- I'm not going to hug your fish.
0:11:37 > 0:11:38OK.
0:11:38 > 0:11:42Speaking of your fish, he's right next to us.
0:11:42 > 0:11:46- Yeah.- And we weren't sitting in water a minute ago, were we?
0:11:46 > 0:11:49- No.- Ant, Fontaine, do you read me?
0:11:51 > 0:11:55Mom, what's happening?
0:11:55 > 0:11:56The island is sinking.
0:11:56 > 0:11:59Well, that would explain some things.
0:11:59 > 0:12:01Yeah, that's not the worst thing.
0:12:01 > 0:12:02Proteus is in here somewhere.
0:12:02 > 0:12:04Proteus!
0:12:05 > 0:12:08Keiko, everyone's getting clear of the island.
0:12:10 > 0:12:12Excellent. Good luck, governor.
0:12:15 > 0:12:17- Will!- Let's go get our kids.
0:12:22 > 0:12:23Can you hear that?
0:12:25 > 0:12:28- It sounds like...- A wave!
0:12:28 > 0:12:29Move! Out of the water!
0:12:29 > 0:12:32- 'Fontaine, what's happening?' - Not now, Mom. Climb!
0:12:34 > 0:12:36Why is there a wave inside a cave?
0:12:36 > 0:12:38- Ask questions later. - What about Jeffrey?
0:12:38 > 0:12:40It's water. He's a fish.
0:12:40 > 0:12:43Hold on!
0:12:43 > 0:12:46Look, past the water.
0:12:46 > 0:12:48What is that?
0:12:48 > 0:12:50WILL: Fontaine, we're at the entrance.
0:12:50 > 0:12:53- We're coming in.- No. Dad, get away from there.
0:12:53 > 0:12:55- What do you mean? What? - I don't know what it is,
0:12:55 > 0:12:58but something huge is heading for the cave entrance.
0:13:05 > 0:13:08Is... Is that what I think it is?
0:13:08 > 0:13:10Amazing!
0:13:13 > 0:13:15Yes. I mean, I suspect...
0:13:15 > 0:13:18But still, seeing it like this.
0:13:18 > 0:13:21You thought this was a possibility and you kept it to yourself?
0:13:21 > 0:13:24What was I supposed to say?
0:13:24 > 0:13:27William, Keiko, now about Tartaruga,
0:13:27 > 0:13:30it's possible that it's not an island at all,
0:13:30 > 0:13:33but is in fact a giant turtle.
0:13:38 > 0:13:41Which means the island isn't sinking.
0:13:43 > 0:13:45- It's diving.- Go after it, Will.
0:13:49 > 0:13:52Ant, this chamber is going to be full of water in seconds.
0:13:52 > 0:13:55We have to get out of here, now.
0:13:55 > 0:13:56Jeffrey.
0:13:57 > 0:13:59I think he wants us to follow him.
0:14:01 > 0:14:03- Ant.- Have faith in the fish.
0:14:03 > 0:14:05THEY INHALE DEEPLY
0:14:20 > 0:14:22THEY GASP
0:14:24 > 0:14:26- An air chamber.- I take it back, Ant.
0:14:26 > 0:14:28I am going to hug Jeffrey.
0:14:28 > 0:14:31Come here, you magnificent fish.
0:14:31 > 0:14:33Finally!
0:14:34 > 0:14:36Proteus.
0:14:36 > 0:14:37Ssh.
0:14:42 > 0:14:44I have a plan, William.
0:14:44 > 0:14:46Get in front of it.
0:14:49 > 0:14:51Stop!
0:14:53 > 0:14:55LOW ROAR
0:14:57 > 0:14:59LOUDER ROAR
0:15:04 > 0:15:07Please, you have their children.
0:15:07 > 0:15:11Just let us retrieve them and you can be on your way.
0:15:15 > 0:15:18LOW ROAR
0:15:23 > 0:15:26You just spoke to a turtle.
0:15:26 > 0:15:29- I did.- Did you know you could do that?
0:15:29 > 0:15:33Of course. Anyone can speak to a turtle.
0:15:33 > 0:15:35I just had no idea it would listen.
0:15:37 > 0:15:40Yes, the final piece!
0:15:40 > 0:15:47And now the secret of Lemuria and the power it holds will be mine.
0:15:52 > 0:15:56Why won't you fit together?
0:15:56 > 0:15:59Well, that's a little awkward.
0:15:59 > 0:16:00WILL: Fontaine.
0:16:00 > 0:16:02- Huh?- We're almost at your location.
0:16:02 > 0:16:04Stay right where you are.
0:16:04 > 0:16:06You...
0:16:06 > 0:16:08Ahh!
0:16:09 > 0:16:10Nereus always said you were the one.
0:16:12 > 0:16:15Perhaps the Ephemychron can only be made whole in your hands.
0:16:17 > 0:16:18Huh?
0:16:20 > 0:16:22- Hmm!- If you think I'm going to help you, you're...
0:16:22 > 0:16:24Absolutely right.
0:16:24 > 0:16:28- He is?- Yeah, Ant's great at this stuff.
0:16:28 > 0:16:30Take the pieces, Ant.
0:16:32 > 0:16:34Ant, dive!
0:16:36 > 0:16:41How long can you hold your breath, little Nektons?
0:16:41 > 0:16:42THEY GASP
0:16:42 > 0:16:45That's right. There's nowhere to run.
0:16:47 > 0:16:50That's right. There's nowhere to run.
0:16:52 > 0:16:54It's over, Proteus.
0:16:54 > 0:16:57Ha! You think this is over?
0:16:57 > 0:17:00You think you won?
0:17:00 > 0:17:03They are not worthy of Lemuria's power.
0:17:03 > 0:17:07I will find it and I will take what's there.
0:17:12 > 0:17:13No! He's getting away.
0:17:13 > 0:17:16Forget about him. We need to get out of here.
0:17:16 > 0:17:18Everyone, back to the rover.
0:17:20 > 0:17:22Jeffrey.
0:17:26 > 0:17:28Come on, Jeffrey.
0:17:38 > 0:17:41Dad, what is that?
0:17:41 > 0:17:44You'll find out soon enough.
0:17:47 > 0:17:48No way.

0:18:01 > 0:18:05- Yes.- Hang on, we spelunked inside a turtle?
0:18:05 > 0:18:08- Yep.- This is the greatest thing EVER!
0:18:08 > 0:18:11I know.
0:18:11 > 0:18:13- Huh?- What is it, Fontaine?
0:18:13 > 0:18:18I don't know. I mean, I know but I don't know what it means.
0:18:18 > 0:18:19Huh?

0:18:30 > 0:18:32What truth?
0:18:32 > 0:18:36Do you know why your family has always been pulled towards the ocean?

0:18:59 > 0:19:03you should have the means to find it.
0:19:17 > 0:19:19It's the water.
0:19:25 > 0:19:27The sea is the key.
0:19:50 > 0:19:53LOW ROAR
