0:00:12 > 0:00:14I'm still detecting oil in the water.
0:00:14 > 0:00:17That's a four-mile long oil slick so far.
0:00:17 > 0:00:20When I analysed it, it was clearly engine oil.
0:00:20 > 0:00:23- Something's leaking. - Maybe someone's in trouble.
0:00:23 > 0:00:25If they're leaking this much oil into the water
0:00:25 > 0:00:28and they're not in trouble, they will be when I catch them.
0:00:31 > 0:00:34- It could be a fishing boat or a freighter.- Or that!
0:00:36 > 0:00:38The Dark Orca!
0:00:38 > 0:00:40Reversing props, full stop.
0:00:40 > 0:00:41Whoa!
0:00:44 > 0:00:47Aronnax to Dark Orca, are you receiving, over?
0:00:47 > 0:00:48STATIC
0:00:48 > 0:00:51Aronnax to Dark Orca, can you hear me?
0:00:51 > 0:00:55STATIC Hmm, that's weird.
0:00:56 > 0:00:58Maybe it's pirate nap time.
0:01:05 > 0:01:07Maybe it's abandoned.
0:01:07 > 0:01:09Maybe this could be a trap.
0:01:09 > 0:01:10I'll take a closer look.
0:01:10 > 0:01:14What part of "this could be a trap" didn't you understand?
0:01:14 > 0:01:16Ant, be careful.
0:01:21 > 0:01:22Huh, no-one here.
0:01:24 > 0:01:26Looks like they left in a hurry.
0:01:27 > 0:01:29They even left their meal just sitting there.
0:01:29 > 0:01:31- I wonder why.- No idea.
0:01:31 > 0:01:33Let's take a closer look.
0:01:41 > 0:01:43Hello?
0:01:44 > 0:01:46Secure the Knights.
0:01:46 > 0:01:48What's happening here?
0:01:57 > 0:01:59Anyone else creeped out?
0:01:59 > 0:02:01I'll stay in the Swamp Knight.
0:02:01 > 0:02:03Keep behind me.
0:02:05 > 0:02:07Hello, anyone?
0:02:17 > 0:02:19Huh? Er...
0:02:31 > 0:02:33I don't think they're here.
0:02:34 > 0:02:36I think it's safe.
0:02:44 > 0:02:47It's like they've completely vanished.
0:02:52 > 0:02:53- CREAKING - Huh!
0:02:57 > 0:02:59What's going on?
0:02:59 > 0:03:01- Huh!?- I have a theory.
0:03:01 > 0:03:04There's only one logical explanation.
0:03:04 > 0:03:06I'm listening.
0:03:06 > 0:03:09The pirates were taken by ghosts.
0:03:11 > 0:03:13My family are explorers.
0:03:13 > 0:03:15We have been for generations.
0:03:15 > 0:03:18While others look up to the stars, we know there are
0:03:18 > 0:03:21an infinite number of things that shine in the darkness below.
0:03:21 > 0:03:25There are things lurking in the seas that long ago vanished into myth.
0:03:25 > 0:03:30My family are the Nektons and we explore The Deep.
0:03:49 > 0:03:53Ghosts? Why do I keep expecting you to have a rational theory?
0:03:53 > 0:03:56I actually have a theory on that. You want to hear it?
0:03:56 > 0:03:58- Hmm, no.- Hmm...
0:03:59 > 0:04:01- TIN CLASHES - Whoa!
0:04:01 > 0:04:03I don't know what you're all seeing,
0:04:03 > 0:04:05but that oil leak isn't slowing down.
0:04:06 > 0:04:09Can we go now, before WE vanish too?
0:04:09 > 0:04:11I'm taking a closer look at the hull.
0:04:14 > 0:04:17One of the ballast water vents is broken.
0:04:17 > 0:04:19The filter cover has a hole in it.
0:04:19 > 0:04:21I'm going to patch it up to stop the leak.
0:04:21 > 0:04:24Good thinking, Mum. We'll keep exploring the ghost angle.
0:04:24 > 0:04:25No, we won't.
0:04:25 > 0:04:28- CREAKING - Huh?
0:04:28 > 0:04:30What was that?
0:04:30 > 0:04:32- I don't know. - CLUNKING
0:04:35 > 0:04:36Ah! Agh!
0:04:36 > 0:04:38BEEPING
0:04:46 > 0:04:48SHE SIGHS
0:04:48 > 0:04:49- CLUNKING - Agh!
0:04:49 > 0:04:52'Hello? Who is this?'
0:04:52 > 0:04:54Hammerhead?
0:04:54 > 0:04:57- This is Will Nekton. - Nekton, what do you want?
0:04:57 > 0:05:00Have you by any chance lost your submarine?
0:05:00 > 0:05:02No.
0:05:02 > 0:05:05Are you sure? Because we found one that sure looks like your sub.
0:05:05 > 0:05:09No, it could be a similar sub, but it's definitely not ours.
0:05:09 > 0:05:13Really? Same rust, same stains.
0:05:13 > 0:05:17And the wheel has "property of Captain Hammerhead" written on it.
0:05:17 > 0:05:20Lots of people are named Hammerhead.
0:05:20 > 0:05:24Er, what about this portrait, which clearly shows you and your family?
0:05:24 > 0:05:25HE GROWLS
0:05:25 > 0:05:28Er, just out of interest, are you guys...OK?
0:05:28 > 0:05:30Why wouldn't we be?
0:05:30 > 0:05:32Nothing strange happening?
0:05:32 > 0:05:33Where are you, exactly?
0:05:33 > 0:05:36HE GRUNTS
0:05:36 > 0:05:40Mum, this mystery just got better.
0:05:40 > 0:05:43Copy. I've managed to stop the leak.
0:05:44 > 0:05:47And there's this large intermittent echo on sonar,
0:05:47 > 0:05:50but it keeps disappearing.
0:05:50 > 0:05:53Ghosts would probably be very hard to pin down on sonar.
0:05:53 > 0:05:55Ant!
0:05:56 > 0:05:59I'm going to try to get a fix on whatever this is.
0:05:59 > 0:06:00It might explain what's going on here.
0:06:00 > 0:06:03OK. Be careful.
0:06:03 > 0:06:04You, too.
0:06:08 > 0:06:10METALLIC ECHOING
0:06:10 > 0:06:12- CLUNKING - Huh!- What was that?
0:06:12 > 0:06:13WHISPERING
0:06:15 > 0:06:17It sounds like voices.
0:06:17 > 0:06:19But we've searched everywhere.
0:06:19 > 0:06:22- There's no-one on board. - No-one human.
0:06:23 > 0:06:26Fontaine. I said, no-one human.
0:06:26 > 0:06:28I heard you.
0:06:28 > 0:06:30Where's your sensible, grounding comeback?
0:06:30 > 0:06:32- I don't have one.- What?
0:06:32 > 0:06:34Dad, tell Fontaine to go back to being a cold,
0:06:34 > 0:06:36logical, calming influence!
0:06:36 > 0:06:38The noises are coming from this direction.
0:06:38 > 0:06:41So, we're going to go in the opposite direction?
0:06:41 > 0:06:44No, we're going to get to the bottom of this.
0:06:45 > 0:06:47That signal is suddenly stronger.
0:06:47 > 0:06:50It seems to be coming from somewhere over there.
0:06:54 > 0:06:56WHISPERING
0:06:59 > 0:07:02- It's coming from... - WHISPERING CONTINUES
0:07:09 > 0:07:11THEY SCREAM
0:07:11 > 0:07:14Nektons! How dare you?
0:07:14 > 0:07:17- Finn?- Erm...
0:07:17 > 0:07:18Hi, Fontaine.
0:07:18 > 0:07:20What are you doing in there?
0:07:20 > 0:07:24Erm, we were locked in here by unknown assailants.
0:07:24 > 0:07:26Er, I don't see any locks.
0:07:26 > 0:07:28Leave - now!
0:07:28 > 0:07:30Where's the rest of your crew?
0:07:30 > 0:07:32I said, get off me sub!
0:07:32 > 0:07:34Was it the ghosts?
0:07:34 > 0:07:35HE GASPS
0:07:35 > 0:07:37What do you know about the ghosts?
0:07:37 > 0:07:40- Is that why you're hiding? - We're not hiding.
0:07:40 > 0:07:42CLUNKING Quick, hide again!
0:07:43 > 0:07:46- What's that?- That's the engine!
0:07:46 > 0:07:47Wargh!
0:07:49 > 0:07:51It's happening again.
0:07:51 > 0:07:53What's happening again?
0:07:53 > 0:07:56The ship is being controlled by other forces!
0:07:56 > 0:07:59THEY SCREAM
0:07:59 > 0:08:02Mum, ghosts have taken the Dark Orca!
0:08:02 > 0:08:04Ant, what did you say?
0:08:04 > 0:08:05We're being hijacked by ghosts!
0:08:12 > 0:08:14You're moving too fast.
0:08:14 > 0:08:15There's a rock pillar ahead of you.
0:08:15 > 0:08:17Going to hit!
0:08:18 > 0:08:20THEY SCREAM
0:08:26 > 0:08:29The Dark Orca's not built to move at this speed.
0:08:29 > 0:08:31It's barely built to move at all.
0:08:31 > 0:08:33Now, that's just hurtful!
0:08:33 > 0:08:36Watch out, there are rock formations everywhere.
0:08:36 > 0:08:40If we don't get control of your sub, you won't have any sub left.
0:08:40 > 0:08:41Let me climb into the air ducts.
0:08:41 > 0:08:43I'll undo some wiring to stop the ship.
0:08:43 > 0:08:45I've sabotaged this sub before.
0:08:45 > 0:08:48We can't trust HIM! Proper sabotage needs a proper pirate.
0:08:48 > 0:08:51Well, if you see any proper pirates, you let me know.
0:08:51 > 0:08:54I'm a great pirate and I'm going!
0:08:54 > 0:08:59Aye, if there's one thing Madeline's good at, it's wrecking things.
0:08:59 > 0:09:04Please! Ant can cause havoc on a scale you can barely imagine.
0:09:04 > 0:09:06- We don't have time for this. - We get it!
0:09:06 > 0:09:09You're both proud of the destructive capabilities of your kids.
0:09:09 > 0:09:12Now, stick them both in the air duct.
0:09:12 > 0:09:15- BOTH:- I'm not getting in a confined space with him/her!
0:09:15 > 0:09:17Ugh! Are you happy now?
0:09:17 > 0:09:18We may have to work together,
0:09:18 > 0:09:20but that doesn't mean I have to talk to you.
0:09:20 > 0:09:22Then why don't you stop talking?
0:09:27 > 0:09:28Wargh!
0:09:28 > 0:09:31- Hammerhead.- Ghosts!
0:09:31 > 0:09:33Hammerhead, snap out of it. Help me!
0:09:36 > 0:09:38THEY GRUNT
0:09:42 > 0:09:43This is the main power array.
0:09:43 > 0:09:45This is where we can do the most damage.
0:09:45 > 0:09:47You think this is my first sabotage?
0:09:47 > 0:09:49Look out! Underwater mountain, dead ahead.
0:09:49 > 0:09:52THEY YELL
0:10:02 > 0:10:04Put your back into it.
0:10:04 > 0:10:05Turn, Hammerhead!
0:10:05 > 0:10:08I'm putting twice as much back into it as you!
0:10:11 > 0:10:15Erm, are you both turning in opposite directions?
0:10:17 > 0:10:19Well, that's a little embarrassing.
0:10:19 > 0:10:21Hard to starboard!
0:10:21 > 0:10:23- HE GASPS - Oh, no.
0:10:23 > 0:10:27- Argh!- Danny Boy, you said you'd fix that.
0:10:27 > 0:10:28I say a lot of things.
0:10:28 > 0:10:30- Look out! - THEY SCREAM
0:10:36 > 0:10:37Hold on, guys!
0:10:39 > 0:10:41Wait. The red one.
0:10:41 > 0:10:43It's always the red one!
0:10:47 > 0:10:50SCREAMING
0:11:00 > 0:11:02'Everyone OK?'
0:11:02 > 0:11:04They... They did it.
0:11:04 > 0:11:06Yes! Oh, that was amazing.
0:11:06 > 0:11:09The way you destroyed the life-support systems.
0:11:09 > 0:11:12I never would have thought to be that irresponsible!
0:11:12 > 0:11:15Me? How about the reckless way you tore out the stabilisers?
0:11:15 > 0:11:17It's like you don't even care about your ship!
0:11:21 > 0:11:24- We just high-fived. - And complimented each other.
0:11:24 > 0:11:26No-one can ever know about this.
0:11:26 > 0:11:28- Agreed.- Eurgh!
0:11:29 > 0:11:33Hey, I'm embarrassed too, but running away seems a bit extreme.
0:11:33 > 0:11:34Huh?
0:11:35 > 0:11:37HE SCREAMS
0:11:37 > 0:11:39Ghosts!
0:11:39 > 0:11:44Aye, the Dark Orca be haunted.
0:11:44 > 0:11:46- CREAKING - Huh?- What?
0:11:47 > 0:11:49Haunted....
0:11:49 > 0:11:50Argh!
0:11:50 > 0:11:52They chased us out of the ducts. Look!
0:11:52 > 0:11:54- Huh? - HE WHIMPERS
0:11:54 > 0:11:56Whoa!
0:11:56 > 0:11:58HE SCREAMS
0:11:58 > 0:12:00- Dad!- Captain!
0:12:02 > 0:12:04They're not ghosts, they're eels!
0:12:06 > 0:12:08Come on, Dad. Wake up.
0:12:09 > 0:12:11Help me sit him up.
0:12:16 > 0:12:21OK, maybe they're eels, but they might be zombie ghost eels.
0:12:21 > 0:12:24They're eating, Ant. I don't think ghosts eat.
0:12:24 > 0:12:27Oh, yeah? Now you're suddenly an expert on the underworld?
0:12:29 > 0:12:32I've never seen anything like them.
0:12:32 > 0:12:35Kaiko, I think you should take a look at these things.
0:12:35 > 0:12:37I'm heading for the moon pool.
0:12:38 > 0:12:40Whoa!
0:12:41 > 0:12:44Will, I'm not getting in there. The moon pool door's gone haywire.
0:12:45 > 0:12:48Ant, did you and Madeline do this?
0:12:48 > 0:12:50Sabotage isn't an exact science.
0:12:50 > 0:12:53What did you want me to see? Can you show them to me?
0:12:53 > 0:12:55Um, let me try to... OK. Look.
0:12:57 > 0:13:01I've seen these before, but not like this.
0:13:01 > 0:13:03Incredible.
0:13:03 > 0:13:05You've seen ghost eels before?
0:13:05 > 0:13:08They're not ghosts, they're babies.
0:13:08 > 0:13:12I've heard reports of them growing to this size,
0:13:12 > 0:13:15but if the babies are over a metre long...
0:13:15 > 0:13:16GROWLING
0:13:20 > 0:13:22- Whoa!- Kaiko!
0:13:24 > 0:13:25- Oh, no!- Kaiko!
0:13:25 > 0:13:29I'm OK, Will. It's a super eel!
0:13:29 > 0:13:31It's heading for the Dark Orca.
0:13:31 > 0:13:34The eel's eggs must have been sucked into the broken water vent.
0:13:34 > 0:13:36It's coming back for its babies.
0:13:36 > 0:13:38IT ROARS
0:13:38 > 0:13:42It's being kept out by the slamming moon pool doors.
0:13:42 > 0:13:44Come on, Dad, wake up!
0:13:46 > 0:13:47Madeline.
0:13:47 > 0:13:52Oh, I had a terrible dream about wet, slippery eels and... Huh?
0:13:52 > 0:13:55HE SCREAMS
0:13:55 > 0:13:58- HE SNORES - Oh.- Oh, for the love of...
0:13:58 > 0:14:00The larvae must have been wriggling through the sub,
0:14:00 > 0:14:03creating havoc with the circuits and wiring.
0:14:03 > 0:14:05So, we weren't possessed by ghosts?
0:14:05 > 0:14:08- No!- No, I mean, of course we weren't.
0:14:08 > 0:14:11I did try to tell the rest of the crew it was ridiculous
0:14:11 > 0:14:13before they abandoned ship, but it's OK.
0:14:13 > 0:14:16- I'll protect you from the eels, Fontaine.- Hah!
0:14:17 > 0:14:21- What?- When we found you, you were literally hiding in a hole.
0:14:21 > 0:14:23I'm not scared of... Argh!
0:14:26 > 0:14:27IT ROARS
0:14:27 > 0:14:29What do we do?
0:14:29 > 0:14:30Eggs!
0:14:32 > 0:14:36- He's right.- Am I missing something? - Eggs!
0:14:36 > 0:14:38Are we even having the same conversation?
0:14:40 > 0:14:43The baby eels like eggs. Even these pickled ones.
0:14:43 > 0:14:45We can use them as a lure.
0:14:45 > 0:14:48We have heaps of pickled eggs in the galley. They last forever.
0:14:48 > 0:14:51- CRASHING - Huh! What was that?
0:14:54 > 0:14:55- Uh-oh.- What?
0:14:55 > 0:14:57The moon pool door is locked open.
0:14:57 > 0:14:59If the super eel sees it...
0:14:59 > 0:15:01Can we close the doors?
0:15:01 > 0:15:04The eel larvae have short-circuited something, again!
0:15:04 > 0:15:05Go get the eggs.
0:15:06 > 0:15:08- Where are you going?- Eggs.
0:15:08 > 0:15:09- Huh?- Eggs!
0:15:09 > 0:15:12Are we even having the same conversation?
0:15:12 > 0:15:13Hurry, Maddie!
0:15:15 > 0:15:17- Will.- What is it, Kaiko?
0:15:17 > 0:15:20Look out. The super eel is coming aboard.
0:15:26 > 0:15:28Kaiko, I need you to be ready.
0:15:28 > 0:15:32- For what?- You and I are going to try to remove the eel.
0:15:32 > 0:15:34I know, I know, it's not going to be easy.
0:15:39 > 0:15:41How do we know if it's even working?
0:15:42 > 0:15:43Never mind.
0:15:44 > 0:15:47Wha...? Eels.
0:15:47 > 0:15:49HE SCREAMS
0:15:50 > 0:15:53Dad, it's working! They're coming after the eggs.
0:15:53 > 0:15:54Draw them to the moon pool room.
0:15:54 > 0:15:56Isn't the moon pool room full of giant eel?
0:15:56 > 0:15:58Your mother and I are working on that.
0:15:58 > 0:16:00Are we really going to do this?
0:16:00 > 0:16:02I mean, how big can it be?
0:16:02 > 0:16:06OK, Danny Boy, hit it. Now!
0:16:09 > 0:16:10Arrgh!
0:16:11 > 0:16:12Grab it, Kaiko!
0:16:14 > 0:16:16Pull!
0:16:16 > 0:16:18Danny Boy, close the moon pool.
0:16:24 > 0:16:27Not going to lie, this plan worked better in my head.

0:18:08 > 0:18:11Dad, try to keep the eel off the crate.
0:18:17 > 0:18:21- Whoa!- That's one way of distracting it.
0:18:21 > 0:18:22Be careful, Fontaine!
0:18:24 > 0:18:27- Yargh!- Try not to hurt it.
0:18:27 > 0:18:30I really don't think that that's a concern.

0:19:08 > 0:19:11Now, get off me sub!
0:19:21 > 0:19:24Oh, would you look at that?
0:19:26 > 0:19:29Nah, it would be heart-warming if it wasn't so gross.
0:19:39 > 0:19:42Danny Boy, are we ready to set sail?

0:19:44 > 0:19:47I've glued the wheel back on and Madeline has unsabotaged
0:19:47 > 0:19:49everything she sabotaged.
0:19:49 > 0:19:52Then, full speed ahead!
0:19:55 > 0:19:59Erm, still some unsabotaging to do by the look of it, captain.

0:20:01 > 0:20:03SHE LAUGHS
0:20:03 > 0:20:06- Having some trouble? - Of course not! We were...
0:20:06 > 0:20:09It's an advanced driving technique.
0:20:10 > 0:20:11Good one, Danny Boy!
0:20:11 > 0:20:13Also, I wanted to make it clear
0:20:13 > 0:20:16that I didn't faint earlier cos of the eels.
0:20:16 > 0:20:20I just, I had low blood sugar.
0:20:21 > 0:20:23HE SCREAMS
0:20:23 > 0:20:25Oops, there he goes again.
