0:00:05 > 0:00:09ANT: 277, 278, 279...
0:00:09 > 0:00:11Ugh!
0:00:11 > 0:00:12Isn't there an app for this?
0:00:12 > 0:00:15If there were an app for monitoring endangered species, trust me,
0:00:15 > 0:00:18I'd use it. Apps don't complain!
0:00:18 > 0:00:22Mom, come on, even you must find this boring.
0:00:22 > 0:00:25Good science needs good discipline, Ant.
0:00:25 > 0:00:27Hey, what spooked them?
0:00:30 > 0:00:32What is that?
0:00:32 > 0:00:34It's got to be...
0:00:34 > 0:00:36..a mutated mollusc!
0:00:36 > 0:00:38Nektons, found you!
0:00:38 > 0:00:39Nereus?
0:00:41 > 0:00:42You're not a mutated mollusc.
0:00:43 > 0:00:46No, not the last time I checked.
0:00:46 > 0:00:50Now, quickly, we need to go to Venezuela.
0:00:50 > 0:00:52- Venezuela?- Venezuela?
0:00:52 > 0:00:55- FONTAINE:- What are we looking at, Nereus?
0:00:55 > 0:00:58The most unstable weather system on the planet.
0:00:59 > 0:01:02That's the Catatumbo storm! Cool!
0:01:02 > 0:01:04A weather system is cool?
0:01:04 > 0:01:08It's an electrical storm that's been going on for hundreds of years.
0:01:08 > 0:01:10Actually, thousands.
0:01:10 > 0:01:12They call it the everlasting storm.
0:01:14 > 0:01:15See, even cooler!
0:01:16 > 0:01:21Uh, right. The problem is, the storm has started rapidly expanding.
0:01:21 > 0:01:25It's tripled in size over the last two weeks.
0:01:25 > 0:01:26How is that possible?
0:01:26 > 0:01:27No idea.
0:01:27 > 0:01:29That's why I need your help.
0:01:31 > 0:01:33Well, we were resuming our search for Lemuria -
0:01:33 > 0:01:37but a huge lightning storm off the coast of Venezuela
0:01:37 > 0:01:38sounds like a bigger priority.
0:01:38 > 0:01:40Not to mention totally awesome!
0:01:42 > 0:01:44I'll plot a course for Venezuela.
0:01:45 > 0:01:47Ugh, great.
0:01:47 > 0:01:49We're going to a huge never-ending electrical storm
0:01:49 > 0:01:51in a giant metal tube.
0:01:51 > 0:01:53What could possibly go wrong?
0:01:58 > 0:02:00My family are explorers.
0:02:00 > 0:02:02We have been for generations.
0:02:02 > 0:02:05While others look up to the stars, we know there are an infinite number
0:02:05 > 0:02:07of things that shine in the darkness below.
0:02:07 > 0:02:12There are things lurking in the seas that long ago vanished into myth.
0:02:12 > 0:02:14My family are the Nektons
0:02:14 > 0:02:16and we explore The Deep.
0:02:45 > 0:02:47We're approaching Catatumbo.
0:02:47 > 0:02:49If you could please stow your tray table and...
0:02:50 > 0:02:53Return to your allocated seat?
0:03:09 > 0:03:11Wow!
0:03:11 > 0:03:13Beautiful.
0:03:13 > 0:03:14Told you.
0:03:18 > 0:03:19The energy is still building.
0:03:19 > 0:03:22The lightning is almost continuous now.
0:03:22 > 0:03:25So, something is turning up the power here?
0:03:25 > 0:03:27We'll soon find out.
0:03:27 > 0:03:30This weather balloon will give us a better read on the storm.
0:03:33 > 0:03:34Let's dive.
0:03:34 > 0:03:36The Aronnax is like a lightning rod up here.
0:03:42 > 0:03:46So, silly question, but we're safe down here, right?
0:03:46 > 0:03:48Much safer than above.
0:03:48 > 0:03:52Lightning tends to dissipate horizontally when it hits the sea.
0:03:52 > 0:03:54So, just to clarify,
0:03:54 > 0:03:58the charge doesn't penetrate downwards anywhere near me?
0:03:58 > 0:03:59Maybe just a bit.
0:04:01 > 0:04:02Relax, Nereus.
0:04:02 > 0:04:04This is so awesome!
0:04:06 > 0:04:09You're right, Jeffrey. This will get millions of likes.
0:04:09 > 0:04:11BEEPING
0:04:11 > 0:04:13Oh, no! Dead battery.
0:04:16 > 0:04:17Sweet!
0:04:27 > 0:04:29We're moving further under the storm now.
0:04:29 > 0:04:31Everyone stay alert.
0:04:35 > 0:04:36Check it out, Jeffrey.
0:04:36 > 0:04:39I can make lightning move slower than the speed of light.
0:04:44 > 0:04:47No way. This lightning, it's backwards!
0:04:47 > 0:04:51- Look! - That's how lightning always works.
0:04:51 > 0:04:52What?
0:04:52 > 0:04:55Lightning starts from the sky and goes to the ground,
0:04:55 > 0:04:58but that part is negatively charged, so it's invisible.
0:04:58 > 0:05:00But I see it.
0:05:01 > 0:05:04No, you see the reverse charge, which is positive.
0:05:04 > 0:05:08It actually travels up but it's so fast, we don't see it that way.
0:05:08 > 0:05:10That is outrageously amazing.
0:05:15 > 0:05:18This is the data from the weather balloon?
0:05:18 > 0:05:19Wind speed, temperature,
0:05:19 > 0:05:23barometric pressure and lightning strike distribution.
0:05:23 > 0:05:28- What's wrong?- This storm is becoming incredibly dangerous.
0:05:28 > 0:05:29How dangerous?
0:05:29 > 0:05:31It could disable electricity grids,
0:05:31 > 0:05:37take out power to Venezuela and knock planes out of the sky.
0:05:37 > 0:05:39That sounds incredibly dangerous.
0:05:41 > 0:05:44Hey, you moved my tablet off the charging mat.
0:05:44 > 0:05:46Yes, I did.
0:05:46 > 0:05:51I apologise for having the audacity to use my OWN charging mat.
0:05:51 > 0:05:5310% charge?
0:05:53 > 0:05:55Fontaine, I was using it for research.
0:05:55 > 0:05:58Good science requires good discipline.
0:05:58 > 0:06:01Then be disciplined and use your own mat.
0:06:01 > 0:06:05OK, how about we put all this energy to good use?
0:06:05 > 0:06:08- Sure.- Ugh...
0:06:08 > 0:06:11Good, because we've just arrived at the centre of the storm.
0:06:20 > 0:06:23ANT'S VOICE SHAKES FROM THE DRILLING
0:06:23 > 0:06:26Is this going to be worth rattling all my teeth for?
0:06:27 > 0:06:30This sea-bed sample will allow us to analyse weather changes here
0:06:30 > 0:06:31over the last few centuries.
0:06:33 > 0:06:34OK, I'm at a maximum depth.
0:06:36 > 0:06:38Analysing core sample now.
0:06:38 > 0:06:42I wonder what was happening around here a thousand years ago!
0:06:42 > 0:06:44Well, they discovered oil here, and...
0:06:44 > 0:06:46Hey!
0:06:46 > 0:06:48Ugh, not again.
0:06:48 > 0:06:49OK. Back to the lab.
0:06:58 > 0:06:59What is that?
0:07:05 > 0:07:07They're electric rays -
0:07:07 > 0:07:10but I've never seen rays emit visible electricity before.
0:07:11 > 0:07:13Plasma arcs?
0:07:13 > 0:07:17That shouldn't be possible underwater.
0:07:17 > 0:07:18Stay very still.
0:07:18 > 0:07:20They're just curious.
0:07:22 > 0:07:23It zapped me.
0:07:23 > 0:07:26Our Knights are shielded, but I still felt a little tingle.
0:07:26 > 0:07:28BEEPING
0:07:28 > 0:07:30And it just recharged my tablet!
0:07:30 > 0:07:33They must be emitting a stable, positive current,
0:07:33 > 0:07:35but that doesn't make any sense.
0:07:35 > 0:07:38Thank you, chargers of the sea!
0:07:43 > 0:07:45Where are they going in such a hurry?
0:07:52 > 0:07:54Wow!
0:07:54 > 0:07:56That's not normal.
0:07:56 > 0:07:59Kaiko, you're going to want to take a look at this.
0:07:59 > 0:08:00Awesome!
0:08:08 > 0:08:10You said lightning couldn't get down this far.
0:08:10 > 0:08:13It can't. It's impossible!
0:08:13 > 0:08:15There was no negative charge from above.
0:08:15 > 0:08:18Just a massive positive surge from below.
0:08:18 > 0:08:19ALARM
0:08:23 > 0:08:25Nektons, you're not safe out there.
0:08:25 > 0:08:29OK, let's just made our way back to the Aronnax. Slowly, calmly...
0:08:31 > 0:08:34OK, forget slowly. Out of here, now!
0:08:39 > 0:08:41Will! Kids!
0:08:44 > 0:08:45That was too close.
0:08:45 > 0:08:47That's it. I'm coming in for a pick-up.
0:08:58 > 0:08:59Let's keep moving.
0:09:11 > 0:09:13- Is everyone on board?- Yes.
0:09:13 > 0:09:14Getting out of here now.
0:09:19 > 0:09:20Hold on!
0:09:28 > 0:09:30Kaiko, Nereus? Are you OK?
0:09:30 > 0:09:32Nothing's responding.
0:09:32 > 0:09:34The computers, the engines, they're all dead.
0:09:34 > 0:09:38I've never been fond of electrical storms.
0:09:38 > 0:09:39Even less so now.
0:09:41 > 0:09:43We need to get away from here.
0:09:43 > 0:09:44Come on, to the engine room.
0:09:47 > 0:09:50Hmm, the lightning boiled the sulphur dioxide.
0:09:50 > 0:09:53We can restore the anodes, but we'll need to recharge.
0:09:54 > 0:09:56What's really happening here, Nereus?
0:09:56 > 0:09:58Why are you asking me?
0:09:58 > 0:10:01Because you always know more than you let on.
0:10:01 > 0:10:04This is not one of those times.
0:10:06 > 0:10:09- Really?- I'm afraid of lightning.
0:10:09 > 0:10:11If I knew there was underwater lightning,
0:10:11 > 0:10:12do you think I'd have come here?
0:10:17 > 0:10:18Oh, no!
0:10:18 > 0:10:20I thought Jeffrey needed extra protection.
0:10:20 > 0:10:23- Really?- It makes total sense, Fontaine.
0:10:26 > 0:10:28If you say so.
0:10:28 > 0:10:30DOOR OPENS
0:10:30 > 0:10:31How we doing?
0:10:31 > 0:10:34We're dead in the water unless we can recharge the battery.
0:10:37 > 0:10:39What is that?
0:10:42 > 0:10:43Phosphorescence?
0:10:43 > 0:10:45Radiation?
0:10:45 > 0:10:48It's coming from that formation on the ocean floor.
0:10:49 > 0:10:51And it's moving!
0:10:52 > 0:10:56Wait a minute - Anteus, turn on the Ephemychron.
0:10:56 > 0:10:57I'm on it.
0:11:02 > 0:11:05We are here, which means...
0:11:05 > 0:11:06What is this?
0:11:08 > 0:11:10Now it makes sense.
0:11:10 > 0:11:12What is it?
0:11:12 > 0:11:13We're right on top of a symbol.
0:11:14 > 0:11:16A symbol for...
0:11:16 > 0:11:18What? A symbol for what?
0:11:20 > 0:11:21A Monumential.
0:11:24 > 0:11:28- But that's...- An electric ray the size of ten football fields.
0:11:34 > 0:11:38Do you think this Monumential is feeding the storm while it sleeps?
0:11:38 > 0:11:41I think that's exactly what's happening.
0:11:41 > 0:11:43- Aargh!- Brace yourselves.
0:11:48 > 0:11:50That's the air ballast, leaking everywhere.
0:11:51 > 0:11:55- We're sinking.- We could go in a Knight and maybe block the valve.
0:11:55 > 0:11:56It's too late.
0:11:56 > 0:11:59But, if we land on that Monumential...
0:11:59 > 0:12:01It will awaken.
0:12:01 > 0:12:02And then?
0:12:02 > 0:12:05Picture an enormous electrical storm,
0:12:05 > 0:12:08moving at will across the whole world.
0:12:08 > 0:12:09That can't be good.
0:12:12 > 0:12:14We're going down.
0:12:14 > 0:12:15What are our options?
0:12:15 > 0:12:17Without ballast, we sink.
0:12:17 > 0:12:21- The bow thrusters?- They need power. Without power, we sink.
0:12:21 > 0:12:24It sounds like all our options involve a lot of sinking.
0:12:24 > 0:12:27I need to find a way to charge the battery.
0:12:27 > 0:12:28Will, we could use a backup plan.
0:12:30 > 0:12:32Kids, ready the Knights.
0:12:32 > 0:12:33We're going to push.
0:12:35 > 0:12:36Jeffrey, stay.
0:12:41 > 0:12:44Dad, is it even possible to push?
0:12:44 > 0:12:47We have to try. Come on.
0:12:47 > 0:12:49We'll try to make it to that ledge.
0:12:49 > 0:12:52All right. Piece of cake.
0:12:52 > 0:12:55OK, jets to full.
0:12:55 > 0:12:56On three.
0:12:56 > 0:12:58One, two, three.
0:13:08 > 0:13:09Push harder.
0:13:09 > 0:13:11If that ray wakes up...
0:13:11 > 0:13:13We know, devastation!
0:13:16 > 0:13:20Come on, Fontaine. Imagine you're pushing me into an open sewer.
0:13:20 > 0:13:21Good idea.
0:13:25 > 0:13:26We're moving.
0:13:26 > 0:13:28Of course we are.
0:13:28 > 0:13:29Keep pushing.
0:13:31 > 0:13:33I don't think we're going to make it.
0:13:33 > 0:13:35Yes...we...are!
0:13:49 > 0:13:51That's it.
0:13:51 > 0:13:52We did it!
0:13:52 > 0:13:55See, kids, you can accomplish anything if you...you....
0:13:55 > 0:13:56ARONNAX CREAKS
0:13:56 > 0:13:59- Oh, no!- Spoke too soon.
0:14:02 > 0:14:04Lift!
0:14:04 > 0:14:06Will, are we safe?
0:14:06 > 0:14:08The Aronnax isn't stable.
0:14:08 > 0:14:11If we did somehow accidentally wake it,
0:14:11 > 0:14:13is there a way to put it to sleep again?
0:14:13 > 0:14:17The ancient Lemurians managed to do it 6,000 years ago.
0:14:17 > 0:14:20They created a device that saved the world.
0:14:20 > 0:14:23The Monumentials were placed in a timeless slumber.
0:14:24 > 0:14:26Maybe not "timeless".
0:14:26 > 0:14:28Is this device handy?
0:14:29 > 0:14:30Alas, no.
0:14:30 > 0:14:31It's in Lemuria.
0:14:32 > 0:14:36Ever noticed that with you, there's always a catch?
0:14:36 > 0:14:38Deep down, she likes me.
0:14:46 > 0:14:49- Will!- We can do this.
0:14:49 > 0:14:51For ever? We need power.
0:14:55 > 0:14:59Hey, what if we let the Aronnax fall on the Monumential?
0:14:59 > 0:15:01Worldwide chaos.
0:15:01 > 0:15:02I thought we'd covered that?
0:15:02 > 0:15:06That's small electric ray recharged my tablet.
0:15:06 > 0:15:08This ray is 1,000 times bigger.
0:15:08 > 0:15:10Maybe it can recharge the Aronnax.
0:15:10 > 0:15:12Like jump-starting a car.
0:15:12 > 0:15:15Hmm. That just might be crazy enough to work.
0:15:15 > 0:15:18We'd need to reverse our polarity and put the Aronnax battery
0:15:18 > 0:15:20in a parallel circuit with the Monumential
0:15:20 > 0:15:22and let the current flow through.
0:15:22 > 0:15:24So that means it could work?
0:15:24 > 0:15:25It could also blow it up.
0:15:28 > 0:15:31I don't like those odds.
0:15:31 > 0:15:34Me neither, but they're the best we've got.
0:15:34 > 0:15:36Nereus, come with me. You too, Jeffrey.
0:15:43 > 0:15:44Keep pushing.
0:15:46 > 0:15:48Come on. Harder!
0:15:50 > 0:15:52Thinking super positive...
0:15:54 > 0:15:56We can't hold it!
0:15:56 > 0:15:57Move!
0:15:59 > 0:16:01There's no way we can stop it.
0:16:02 > 0:16:03No!
0:16:05 > 0:16:08Kaiko, you need to get out while there's still time.
0:16:08 > 0:16:09Just working on something right now.
0:16:09 > 0:16:12You don't understand, the Aronnax is in freefall.
0:16:12 > 0:16:14Look!
0:16:14 > 0:16:15- Kaiko!- Nereus!
0:16:17 > 0:16:20Sorry, had to reroute some circuits before I left.
0:16:20 > 0:16:22Mom, you're going to use the cable
0:16:22 > 0:16:24to get a charge from the Monumential?
0:16:24 > 0:16:25We're going to try. Come on.
0:16:27 > 0:16:28We have to be quick.
0:16:35 > 0:16:37It's going to flare up again.
0:16:39 > 0:16:41It's going to miss!
0:16:41 > 0:16:44The cable has to touch the dorsal mount.
0:16:46 > 0:16:47I'm going to try and guide it.
0:16:50 > 0:16:52He's not going to make it alone.
0:16:52 > 0:16:55This is going to take all of us together. Come on.
0:16:56 > 0:16:57Push.
0:17:02 > 0:17:03I think it's working, Dad.
0:17:06 > 0:17:09That's enough. Everyone back.
0:17:09 > 0:17:10Hurry!
0:17:18 > 0:17:19Jeffrey!
0:17:21 > 0:17:23I've got you, little buddy!
0:17:38 > 0:17:39Is everyone OK?
0:17:40 > 0:17:42We're... We're fine.
0:17:42 > 0:17:44Did we do it?
0:17:44 > 0:17:45Over there!
0:17:49 > 0:17:52The Aronnax has power.
0:17:52 > 0:17:54It's still falling.
0:17:54 > 0:17:55Hang on, Nereus.
0:17:56 > 0:17:59Whooooaa!
0:17:59 > 0:18:03This day has been then an unending procession of peril!
0:18:03 > 0:18:04Whoa!
0:18:12 > 0:18:14Come on, Kaiko...
0:18:14 > 0:18:15Come on!
0:18:23 > 0:18:25- Oh, no!- Come on, come on.
0:18:40 > 0:18:42Woohoo!
0:18:42 > 0:18:44Way to go, Mom!
0:18:44 > 0:18:47I can't believe your crazy idea worked.
0:18:47 > 0:18:49Yeah, my crazy-good idea!
0:18:50 > 0:18:52KAIKO LAUGHS
0:18:52 > 0:18:54It was blind, crazy luck, Ant.
0:19:02 > 0:19:04Its eyes are open!
0:19:04 > 0:19:05It's woken up!
0:19:08 > 0:19:10It's OK, Ant.
0:19:10 > 0:19:12Electric rays don't have eyelids.
0:19:12 > 0:19:15Their eyes are always open. That doesn't mean it's awake.
0:19:16 > 0:19:21Mom, have I ever told you how glad I am that you're a marine biologist?
0:19:21 > 0:19:24Remember that the next time I get you to count fish.
0:19:24 > 0:19:26Isn't there an app for that?
0:19:29 > 0:19:32Frequency of lightning has returned to normal.
0:19:32 > 0:19:34It looks like the Monumential has been drained
0:19:34 > 0:19:36of its excess electricity.
0:19:36 > 0:19:39And the relationship between the Monumential and the storm above
0:19:39 > 0:19:41- seems to have balanced.- For now.
0:19:44 > 0:19:45What do you mean?
0:19:46 > 0:19:47Things are stirring.
0:19:49 > 0:19:50And not just me.
0:19:52 > 0:19:54The oceans are changing.
0:19:54 > 0:19:58The balance is shifting, all over the world.
0:19:58 > 0:20:02Ugh, he's gone all cryptic and mysterious again.
0:20:02 > 0:20:05I think if you grow a beard like that, you have to be mysterious.
0:20:05 > 0:20:08I'm SO growing a mystery beard when I'm older.
0:20:08 > 0:20:10This is why we have to locate Lemuria.
0:20:10 > 0:20:14We need to find the device that controls the Monumentials.
0:20:14 > 0:20:17Dad's right. And sooner rather than later.
0:20:17 > 0:20:20Why? What's bugging you now?
0:20:20 > 0:20:23See this symbol that marked the location of the Monumential?
0:20:23 > 0:20:24Yeah?
0:20:25 > 0:20:28Look how many more there are out there.
0:20:28 > 0:20:31Every single one a Monumential.
0:20:33 > 0:20:35- Awesome!- Oh, no.
0:20:35 > 0:20:37Here we go again!
0:20:37 > 0:20:40Oh, Fontaine, always the sceptic!
0:20:40 > 0:20:41Ugh!
