0:00:04 > 0:00:06Quickly! Help me unload!
0:00:07 > 0:00:08I need to get back out there!
0:00:08 > 0:00:12What are you crazy? You can't go back out there. That storm!
0:00:12 > 0:00:14Forget the storm. Something's happening.
0:00:14 > 0:00:16It's like the sea is full of fish!
0:00:16 > 0:00:18The sea is always full of fish.
0:00:18 > 0:00:20No, no.
0:00:20 > 0:00:23It's like every fish in the ocean is right out there.
0:00:23 > 0:00:24Look out!
0:00:33 > 0:00:34Did you see...?
0:00:34 > 0:00:36M-my boat... Where's my boat?
0:00:36 > 0:00:38It was huge.
0:00:38 > 0:00:40No... My Boat!
0:00:43 > 0:00:44My family are explorers.
0:00:44 > 0:00:47We have been for generations.
0:00:47 > 0:00:48While others look up to the stars,
0:00:48 > 0:00:51we know there are an infinite number of things
0:00:51 > 0:00:53that shine in the darkness below.
0:00:53 > 0:00:56There are things lurking in the seas that long ago vanished into myth.
0:00:56 > 0:00:58My family are explorers.
0:00:58 > 0:01:00And we explore...
0:01:00 > 0:01:01The Deep!
0:01:13 > 0:01:15Ant, what are you doing?
0:01:15 > 0:01:16I'm training it.
0:01:16 > 0:01:18You're training a fish?
0:01:18 > 0:01:20- Yep.- To do what?
0:01:20 > 0:01:23- To fetch. - You're training your fish to fetch?
0:01:23 > 0:01:24Yep.
0:01:24 > 0:01:25You're deluded.
0:01:25 > 0:01:27It could be very useful.
0:01:27 > 0:01:28How, Ant?
0:01:28 > 0:01:30Erm...
0:01:30 > 0:01:32- How?- I'm not sure yet, Fontaine.
0:01:32 > 0:01:34But I'm sure, once I've trained him,
0:01:34 > 0:01:36I'll find all sorts of practical applications.
0:01:36 > 0:01:38A fish has, like, a three-second memory.
0:01:38 > 0:01:41So, in the highly-unlikely event you manage to train the fish,
0:01:41 > 0:01:43it will just forget what it's learned straight away.
0:01:43 > 0:01:46That's not true! You know it's not true.
0:01:46 > 0:01:48Have faith in my fish!
0:01:48 > 0:01:50You ARE deluded.
0:01:50 > 0:01:53I'll prove it! Get into the Moon Pool.
0:01:53 > 0:01:54I'm going to humour you,
0:01:54 > 0:01:57but I'm also going to mock you when this doesn't work.
0:02:00 > 0:02:02All right. Here's our chance, Jeffrey...
0:02:02 > 0:02:04You named your fish Jeffrey?
0:02:04 > 0:02:08Ignore her, Jeffrey, she can never understand us.
0:02:08 > 0:02:09Now...
0:02:09 > 0:02:10Fetch!
0:02:13 > 0:02:14Fetch!
0:02:16 > 0:02:17You're deluded.
0:02:19 > 0:02:21Can I get out now, Ant?
0:02:21 > 0:02:24Or do you and Jeffrey have other failures to show me?
0:02:27 > 0:02:28Naaagh!
0:02:28 > 0:02:30Mom!
0:02:30 > 0:02:32That never gets old.
0:02:32 > 0:02:34What's up?
0:02:34 > 0:02:37- I'm teaching my fish to fetch. - No. He isn't.
0:02:37 > 0:02:40Ant, you should know not to involve your sister in these things.
0:02:40 > 0:02:42Fontaine, have faith in the fish.
0:02:42 > 0:02:43Where's your dad?
0:02:43 > 0:02:46He's in the study, staring at some old map.
0:02:48 > 0:02:50We have newer maps.
0:02:50 > 0:02:51I know, Kaiko.
0:02:51 > 0:02:55We have satellite maps. All sorts of technology went in to them.
0:02:55 > 0:02:57Some of them aren't even drawn in pencil.
0:02:57 > 0:02:59I know, Kaiko.
0:02:59 > 0:03:02- Then why...?- There are parts of this map that are surprisingly accurate
0:03:02 > 0:03:07and there are parts that are marked "Here be dragons".
0:03:07 > 0:03:09Will, we have newer maps.
0:03:09 > 0:03:13A week ago, there was an earthquake off the coast of Greenland.
0:03:13 > 0:03:15Since then, there have been some strange reports.
0:03:15 > 0:03:18What sort of reports?
0:03:18 > 0:03:20Sightings. Monster sightings.
0:03:20 > 0:03:22Plus, a fishing boat went missing.
0:03:23 > 0:03:27This is a map of the exact area and I was just thinking...
0:03:27 > 0:03:29what if there were?
0:03:29 > 0:03:31- Were what? - DOOR OPENS
0:03:31 > 0:03:32Dragons!
0:03:32 > 0:03:34Yes!
0:03:34 > 0:03:37It's probably not dragons.
0:03:37 > 0:03:40"Probably not" has never stopped us before.
0:03:40 > 0:03:44So, we're going to Greenland to search for dragons?
0:03:44 > 0:03:46What do you think normal families do on a Sunday?
0:03:46 > 0:03:48Who cares?! Dragons!
0:04:03 > 0:04:04Are we there yet?
0:04:04 > 0:04:08We're exactly two minutes closer to Greenland than we were
0:04:08 > 0:04:09the last time you asked.
0:04:09 > 0:04:14Which means I have time to fill you in on what we're looking for.
0:04:14 > 0:04:17- In 1734...- Aw, Dad!
0:04:17 > 0:04:19Only you could take something as awesome as dragons
0:04:19 > 0:04:21and turn it into history.
0:04:21 > 0:04:25In 1734 something was sighted off the coast of Greenland.
0:04:25 > 0:04:28The founder of Greenland's capital city, Hans Egede,
0:04:28 > 0:04:30and all of those aboard his ship,
0:04:30 > 0:04:33reported seeing a sea serpent larger than their whole ship.
0:04:33 > 0:04:35There have been sea monster sightings like this
0:04:35 > 0:04:39throughout history. In fact, my parents swore they encountered one
0:04:39 > 0:04:41while searching for Lost Lemuria.
0:04:41 > 0:04:43Really? I didn't know that.
0:04:43 > 0:04:45WEIRD, FAINT NOISE
0:04:47 > 0:04:49- Full stop!- What is it?
0:04:49 > 0:04:51I saw...something.
0:04:51 > 0:04:52Bring us about.
0:04:57 > 0:04:58What are we looking for?
0:04:58 > 0:05:00I'm not entirely sure...
0:05:01 > 0:05:03Wait, there!
0:05:03 > 0:05:04What is that?
0:05:04 > 0:05:06I'd say that's the missing fishing boat.
0:05:06 > 0:05:09We're still 20 kilometres away from the Greenland coast.
0:05:09 > 0:05:12- What's it doing out here? - I don't know.
0:05:12 > 0:05:14Well, let's go take a closer look.
0:05:19 > 0:05:21How is it your turn in the White Knight?
0:05:21 > 0:05:23Remember you went out to see that "fascinating"
0:05:23 > 0:05:25deep-sea cucumber last week?
0:05:25 > 0:05:27Ugh, it was a cucumber!
0:05:27 > 0:05:28It was a turn.
0:05:34 > 0:05:35Are you ready, big guy?
0:05:35 > 0:05:37You're taking your fish?
0:05:37 > 0:05:38He needs the exercise.
0:05:38 > 0:05:41But he got all that exercise playing fetch.
0:05:41 > 0:05:42Don't mock me.
0:05:42 > 0:05:44Have faith in the fish.
0:05:56 > 0:05:58Anything strange?
0:05:58 > 0:06:00Aside from a fishing boat being miles away
0:06:00 > 0:06:01from where it went missing?
0:06:01 > 0:06:03Actually...
0:06:03 > 0:06:05I'd call this strange.
0:06:05 > 0:06:07Half the boat is just...gone.
0:06:07 > 0:06:09And it's still full of fish!
0:06:09 > 0:06:11I'm going in for a closer look.
0:06:11 > 0:06:12Be careful.
0:06:15 > 0:06:17What's that? To the left, Ant.
0:06:19 > 0:06:22It looks like...a tooth.
0:06:25 > 0:06:27It's too big to be a tooth.
0:06:27 > 0:06:30I think you'd better come back to the sub, Ant.
0:06:30 > 0:06:31Yeah.
0:06:31 > 0:06:35I mean, I'm fine, really, but, uh, Jeffrey's getting a bit nervous.
0:06:35 > 0:06:36- ALARM - What?
0:06:38 > 0:06:40Ant, get out of there, now!
0:06:47 > 0:06:48Ahh!
0:06:57 > 0:06:59Uhhh...
0:06:59 > 0:07:00Ant, get out of there!
0:07:00 > 0:07:02No, don't move!
0:07:02 > 0:07:04Stay very, very still.
0:07:21 > 0:07:23The fishing is the best we've ever seen!
0:07:23 > 0:07:25You go out there, and you won't be coming back.
0:07:25 > 0:07:29Hah! There's no such thing as sea monsters.
0:07:29 > 0:07:31I saw it!
0:07:31 > 0:07:36I was young, but I saw that beast as clear as day.
0:07:36 > 0:07:38It could swallow your boat whole.
0:07:38 > 0:07:41Here be dragons, boy.
0:07:41 > 0:07:43There's no such thing.
0:07:43 > 0:07:47Oh. Then, why aren't you on your boat, boy?
0:07:47 > 0:07:52Why are you still arguing if the fishing's good?
0:07:52 > 0:07:53You're right. I'm going out.
0:07:53 > 0:07:57You superstitious lot can stay here and stay poor.
0:07:57 > 0:08:00I'm coming back with enough fish for the wholeAGHHHHH!
0:08:02 > 0:08:05Eh...what are you doing, boy?
0:08:05 > 0:08:06Huh?
0:08:06 > 0:08:09You never seen a submarine before?
0:08:20 > 0:08:23Hi, I'm Will Nekton and this is my family.
0:08:23 > 0:08:26We hear you may have some monster trouble?
0:08:26 > 0:08:28Oh, the dragon's no trouble.
0:08:28 > 0:08:31We'll just stay out of the water for a while.
0:08:31 > 0:08:33He'll be gone soon.
0:08:33 > 0:08:36You...have a young man hugging you.
0:08:36 > 0:08:38So I...so I noticed, yes.
0:08:40 > 0:08:42You were talking about the dragon?
0:08:42 > 0:08:46Aye. I've seen him before, 40 years ago.
0:08:46 > 0:08:49I know he was around 40 years before that.
0:08:49 > 0:08:51And 40 years before that.
0:08:51 > 0:08:54It's been the same every time.
0:08:54 > 0:08:56An earthquake, then a monster.
0:08:56 > 0:09:00Then, another earthquake and no monster.
0:09:00 > 0:09:02Why every 40 years?
0:09:02 > 0:09:03How should I know?
0:09:03 > 0:09:06You seem familiar.
0:09:06 > 0:09:08Yes. I...I get that a lot.
0:09:08 > 0:09:11It's real, isn't it? I saw it.
0:09:11 > 0:09:14Yeah. We saw it, too. It's definitely real.
0:09:14 > 0:09:17It took my boat! Can you find it?
0:09:17 > 0:09:19Well, we found half of it.
0:09:19 > 0:09:21Half of it?!
0:09:21 > 0:09:23Yes. Sorry, uh, half of your boat was eaten.
0:09:23 > 0:09:24What?!
0:09:24 > 0:09:27Actually, then the other half of your boat was eaten.
0:09:27 > 0:09:28WHAT?!
0:09:28 > 0:09:30I-I'm confused...
0:09:30 > 0:09:34Hello, Antaeus Nekton. My name is Nereus.
0:09:34 > 0:09:36How do you know my full name?
0:09:36 > 0:09:38Antaeus, the others won't understand.
0:09:38 > 0:09:42You see, the dragon isn't important.
0:09:42 > 0:09:45Trust me, it's important. I was almost eaten by it.
0:09:45 > 0:09:49The creature is nothing compared to the secret it guards.
0:09:49 > 0:09:52Uhh, I'm listening.
0:09:52 > 0:09:55This was no random earthquake.
0:09:55 > 0:09:58Out there, a trench has opened,
0:09:58 > 0:10:01and soon it will close again.
0:10:01 > 0:10:04Inside the trench is the creature's lair.
0:10:04 > 0:10:08Inside the lair, lies the secret.
0:10:08 > 0:10:11What is this secret? How do we find it?
0:10:11 > 0:10:14You'll know you're there when you can breathe beneath the waves.
0:10:14 > 0:10:17What? What's that supposed to mean?
0:10:17 > 0:10:19Oh, you'll find it.
0:10:19 > 0:10:23I have great faith in you, Antaeus Nekton.
0:10:23 > 0:10:26In fact, I think it could all come down to you.
0:10:26 > 0:10:33If your family needs persuading, give this to your father.
0:10:33 > 0:10:37Remember, the sea is the key.
0:10:37 > 0:10:39The sea is the key.
0:10:39 > 0:10:42Wait, why?
0:10:42 > 0:10:43Huh?
0:10:43 > 0:10:46I'm not insured for sea monsters!
0:10:46 > 0:10:48Mom, Dad - we got to go. Now.
0:10:48 > 0:10:49What is it?
0:10:49 > 0:10:51I'll explain once we're moving. If we don't go now,
0:10:51 > 0:10:54we'll have to wait another 40 years. And I am way too impatient for that.
0:11:05 > 0:11:08It makes sense for the trench to be somewhere around here,
0:11:08 > 0:11:10where the earthquake was strongest.
0:11:10 > 0:11:11This makes no sense.
0:11:11 > 0:11:14Trenches don't just open and close every 40 years.
0:11:14 > 0:11:16According to Nereus, they do.
0:11:16 > 0:11:19And we just blindly believe strange old men on piers now?
0:11:19 > 0:11:21Does it matter? What's the worst that could happen?
0:11:21 > 0:11:26Well, it sounds like a trench could close on us, or we could be eaten.
0:11:26 > 0:11:29Have you ever eaten submarine? Not the tastiest.
0:11:29 > 0:11:33Ant, your sister's right. We have no reason to trust this man.
0:11:34 > 0:11:36Dad, he said to give this to you.
0:11:40 > 0:11:42What is it?
0:11:42 > 0:11:43He knew my parents.
0:11:45 > 0:11:47Oh, Will.
0:11:47 > 0:11:49The tooth!
0:11:49 > 0:11:51Our grandparents knew about the creature, too!
0:11:51 > 0:11:54I have a lot of questions for this Nereus.
0:11:54 > 0:11:56Dad, Nereus said the trench is going to close.
0:11:56 > 0:11:58Questions will have to wait.
0:11:58 > 0:12:01Fontaine, set a course for the hypocentre of the quake.
0:12:08 > 0:12:11The earthquake originated somewhere around here.
0:12:11 > 0:12:13But I don't know what we're looking for...
0:12:13 > 0:12:15Never mind.
0:12:15 > 0:12:16What is it?
0:12:16 > 0:12:18The sea floor just disappeared.
0:12:20 > 0:12:21Incredible.
0:12:21 > 0:12:25This trench isn't on any maps I've ever seen.
0:12:25 > 0:12:27Yeah, Dad, but you look at some pretty old maps.
0:12:27 > 0:12:29No, I mean no maps, at all.
0:12:29 > 0:12:32This trench doesn't exist.
0:12:32 > 0:12:34I think this proves we can trust the old man.
0:12:36 > 0:12:37Taking us in.
0:12:42 > 0:12:44According to the 3D scanners,
0:12:44 > 0:12:47the walls of the trench just keep going down.
0:12:47 > 0:12:49This trench is deep. Very deep.
0:12:54 > 0:12:58But there's something... It looks like a hole in the wall up ahead.
0:12:58 > 0:12:59There!
0:13:00 > 0:13:03The dragon's lair.
0:13:03 > 0:13:06But the scanners don't detect any creatures present.
0:13:06 > 0:13:08Then, let's go snoop around.
0:13:22 > 0:13:25Wow, something has been feeding here!
0:13:25 > 0:13:27Stay close, Ant.
0:13:30 > 0:13:32There's something up ahead.
0:13:39 > 0:13:42I don't know how, but the air in this chamber is breathable.
0:13:42 > 0:13:44- That's what he said!- Who?
0:13:44 > 0:13:47Nereus. He said we'd be able to breathe beneath the waves.
0:13:47 > 0:13:48Shall we go for a walk?
0:13:53 > 0:13:56OK. This was totally worth it.
0:13:56 > 0:13:57Mom! Dad!
0:14:00 > 0:14:01Incredible.
0:14:04 > 0:14:06The inscriptions... they look Lemurian.
0:14:06 > 0:14:10Look here. See these lines running down the sides?
0:14:10 > 0:14:11It looks like this thing opens up!
0:14:11 > 0:14:14ALARM The ancient stone is alarmed?!
0:14:14 > 0:14:15No. It's the Rover!
0:14:16 > 0:14:18The creature is coming!
0:14:18 > 0:14:20Move! Move!
0:14:20 > 0:14:22Hang on. There's something...
0:14:22 > 0:14:23Ant. Come on!
0:14:25 > 0:14:28The sea is the key.
0:14:33 > 0:14:35- What are you doing?! - Ant, we need to go, now!
0:14:35 > 0:14:36I think I worked it out!
0:14:39 > 0:14:41The sea is the key.
0:14:49 > 0:14:50Yes!
0:14:51 > 0:14:53This is the secret.
0:14:53 > 0:14:55Nrr... Nhhh!
0:14:55 > 0:14:56A little help?
0:14:56 > 0:14:57Hurry!
0:15:02 > 0:15:03No sign of him yet.
0:15:04 > 0:15:06I take that back!
0:15:06 > 0:15:07Whoa!
0:15:12 > 0:15:14- ALL:- Aargh!
0:15:14 > 0:15:15Whoa!
0:15:19 > 0:15:20Oh, no!
0:15:21 > 0:15:24Aronnax to Rover. Aronnax to Rover.
0:15:24 > 0:15:25Ant!
0:15:25 > 0:15:28Keep the Moon Pool open, we're almost there!
0:15:28 > 0:15:29Hold on.
0:15:29 > 0:15:32Whoaaaa!
0:15:32 > 0:15:33Ugh! Ahhh!
0:15:33 > 0:15:34STATIC
0:15:34 > 0:15:35Aronnax to Rover!
0:15:35 > 0:15:37Ahhhhhh!
0:15:39 > 0:15:41Mum! Dad!
0:15:42 > 0:15:43Aargh!
0:15:47 > 0:15:50Stay calm. Stay quiet.
0:15:50 > 0:15:52There is no reason for the creature to attack.
0:15:52 > 0:15:56We're not a threat to something that large and we are not food.
0:15:58 > 0:15:59How are we not food?
0:15:59 > 0:16:01Sure, we're a round piece of metal and glass,
0:16:01 > 0:16:03but we have a soft, juicy inside!
0:16:03 > 0:16:04Shh.
0:16:07 > 0:16:08Hold on!
0:16:08 > 0:16:09Whoa!
0:16:14 > 0:16:16Whoa!
0:16:16 > 0:16:17A tremor?!
0:16:19 > 0:16:20It's closing.
0:16:26 > 0:16:27Why's it leaving?
0:16:27 > 0:16:29Maybe it knows something we don't.
0:16:29 > 0:16:31Let's get out of here!
0:16:31 > 0:16:32We can't. The power's out.
0:16:34 > 0:16:35What about the homing beacon?
0:16:37 > 0:16:39It's gone. It must have been knocked off by the creature.
0:16:39 > 0:16:41All right, breathe calmly.
0:16:41 > 0:16:43Without power, we only have so much air.
0:16:43 > 0:16:44Ant will find us.
0:16:44 > 0:16:46Without the homing beacon?
0:16:46 > 0:16:48Ant WILL find us.
0:16:53 > 0:16:54No, no, no!
0:16:54 > 0:16:56What happened to the homing beacon?
0:16:56 > 0:16:58I can't find you without the beacon!
0:17:00 > 0:17:01That's it!
0:17:01 > 0:17:03Where's that tracker?
0:17:03 > 0:17:05This just has to work, there's no other way!
0:17:05 > 0:17:06Yes!
0:17:06 > 0:17:10OK, I'll put the tracker on you, and you fetch my family.
0:17:10 > 0:17:11Got it?
0:17:14 > 0:17:15Fetch!
0:17:17 > 0:17:21Jeffrey, I need you to fetch. Please!
0:17:21 > 0:17:23Oh, please.
0:17:23 > 0:17:24Fetch!
0:17:27 > 0:17:29My family needs me.
0:17:30 > 0:17:31Please...
0:17:35 > 0:17:36Huh?
0:17:36 > 0:17:37Jeffrey?
0:17:43 > 0:17:45We're coming!
0:17:47 > 0:17:50The Rover door has a manual release.
0:17:50 > 0:17:52And you want to drown, instead of being crushed?
0:17:52 > 0:17:56There's one suit in here capable of surviving at this depth.
0:17:56 > 0:17:57No!
0:17:57 > 0:18:00No, I won't put it on. I won't leave you!
0:18:00 > 0:18:03Fontaine, we don't have time. Just take it.
0:18:03 > 0:18:04Please.
0:18:06 > 0:18:07CRASH!
0:18:07 > 0:18:08There.
0:18:08 > 0:18:10Now, it's no good to anyone.
0:18:10 > 0:18:13You know, when we survive this,
0:18:13 > 0:18:15you and I are going to have a serious talk about acts
0:18:15 > 0:18:19of defiance that don't destroy very expensive equipment.
0:18:19 > 0:18:20Huh?
0:18:23 > 0:18:25Isn't that Ant's fish?
0:18:25 > 0:18:26No way...
0:18:30 > 0:18:31No way!
0:18:31 > 0:18:34Have faith in the fish.
0:18:34 > 0:18:35Oh, no.
0:18:35 > 0:18:37The trench is closing!
0:18:37 > 0:18:38Whoa!
0:18:40 > 0:18:41Whoaaaa!!
0:18:43 > 0:18:45Ugh!
0:18:45 > 0:18:46Huh?
0:18:48 > 0:18:49Need a lift?
0:18:49 > 0:18:50It's Ant!
0:18:50 > 0:18:52Ha-ha! I told you he'd find us!
0:18:54 > 0:18:56Yeeee-ha-ha-ha!
0:18:58 > 0:19:00Ant, we're clear! Punch it!
0:19:00 > 0:19:01Hold onto something!
0:19:01 > 0:19:03We're going to have to move fast!
0:19:08 > 0:19:10Whoa!
0:19:16 > 0:19:17Whoo-hoo! Made it!
0:19:20 > 0:19:21Jeffrey!
0:19:22 > 0:19:25I think someone is owed an apology?
0:19:26 > 0:19:28OK. You were right, Ant.
0:19:28 > 0:19:31I should have had faith in your fish. I'm sorry.
0:19:31 > 0:19:34Not me! Jeffrey.
0:19:34 > 0:19:36You want me to apologise to a fish?
0:19:39 > 0:19:41Sorry, Jeffrey.
0:19:52 > 0:19:53Is it...?
0:19:53 > 0:19:54Yes.
0:19:54 > 0:19:57It's written in Lemurian.
0:19:57 > 0:19:58I'm sure of it.
0:19:58 > 0:19:59I knew it!
0:19:59 > 0:20:02Will, are you OK?
0:20:02 > 0:20:03I'm fine, Kaiko.
0:20:03 > 0:20:06I just wish my parents were still here to see this.
0:20:06 > 0:20:09Our family has been searching for Lemuria for so long
0:20:09 > 0:20:10and this could be it.
0:20:10 > 0:20:12The key to the sunken world.
0:20:12 > 0:20:16This could hold the answer to the biggest mystery on the planet!
0:20:16 > 0:20:19Amazing! Can you read it?
0:20:19 > 0:20:20Not a word.
0:20:21 > 0:20:23And it begins.
0:20:23 > 0:20:26This should be...interesting.
