0:00:42 > 0:00:44- We've been exploring for hours.
0:00:45 > 0:00:47- There's nothing there but ghosts.
0:00:48 > 0:00:51- Whose ghosts? - Pirate ghosts, which means treasure.
0:00:54 > 0:00:56- What's that?
0:00:57 > 0:00:59- A treasure chest. I told you so.
0:01:03 > 0:01:05- Hah! It's not treasure.
0:01:12 > 0:01:13- It's someone's rubbish.
0:01:14 > 0:01:16- I'm fed up. Come on, Crannog.

0:01:43 > 0:01:46- What is it? Pull it off.
0:01:46 > 0:01:48- Steady on.
0:01:48 > 0:01:50- It's a plastic bag.
0:01:50 > 0:01:52- What's that?
0:01:53 > 0:01:55- Something large.
0:01:56 > 0:01:59- It's coming straight for us.
0:02:01 > 0:02:05- Look at this. That's a signal - from a female turtle.
0:02:06 > 0:02:07- We tagged her three years ago.
0:02:07 > 0:02:10- We tagged her three years ago.- - Great. Fantastic.
0:02:10 > 0:02:13- She's in a hurry. - She's following something.
0:02:34 > 0:02:36- Why is she back?
0:02:36 > 0:02:38- To lay her eggs - on one of our beaches.
0:02:39 > 0:02:43- The leatherback turtle is very rare. - You don't see many of them.
0:02:44 > 0:02:47- It would be great - if the eggs hatched here.
0:02:47 > 0:02:51- She's heading for the centre - at great speed.
0:02:51 > 0:02:53- Dive, Oli, dive.
0:02:57 > 0:02:58- Whoa!
0:02:59 > 0:03:01- She's chasing Sid.
0:03:03 > 0:03:06- Wena, save me. I'm in danger.
0:03:10 > 0:03:11- Whoa!
0:03:11 > 0:03:12- Whoa!- - Shoo!
0:03:12 > 0:03:14- Go on.
0:03:17 > 0:03:19- What kind of creature was that?
0:03:20 > 0:03:22- A leatherback turtle.
0:03:22 > 0:03:25- She thought - this bag was a jellyfish.
0:03:25 > 0:03:27- It's a turtle's favourite food.
0:03:29 > 0:03:33- She wasn't after you, - but the plastic bag.
0:03:33 > 0:03:37- Bags are dangerous. Had she eaten - it, she would have choked to death.
0:03:38 > 0:03:42- Good work, Sid. - You saved a turtle's life.
0:03:42 > 0:03:44- Well done, Sid. Thank you.
0:03:45 > 0:03:47- You're a hero.
0:03:49 > 0:03:51- That's true.
0:03:51 > 0:03:53- Yes, I saved a turtle's life.
0:03:59 > 0:04:00- Listen, we have work to do.
0:04:01 > 0:04:05- I want you to follow the turtle. - Hopefully, she's lay her eggs.
0:04:05 > 0:04:11- In the meantime, you have - a great opportunity to watch her.
0:04:11 > 0:04:15- I know my turtle is quick. - She almost caught me.
0:04:16 > 0:04:18- Your turtle?
0:04:18 > 0:04:20- Sid saved her life.
0:04:20 > 0:04:24- Since it's your turtle, - you'd better go with them.
0:04:25 > 0:04:27- I agree.
0:04:27 > 0:04:29- Let's see what we can learn.
0:04:29 > 0:04:31- OK, dive.
0:04:40 > 0:04:44- She looks very happy - in this part of the sea.
0:04:48 > 0:04:50- Sid looks happy, too.
0:04:58 > 0:05:00- She's so fast.
0:05:01 > 0:05:05- Leatherback turtles are - the fastest in the sea. Go, turtle!
0:05:05 > 0:05:07- No, don't go down there.
0:05:08 > 0:05:12- You have to be careful - if you're laying your eggs tonight.
0:05:18 > 0:05:21- There they go.
0:05:29 > 0:05:31- She can dive brilliantly.
0:05:38 > 0:05:40- BEEPING
0:05:42 > 0:05:46- She's heading for the Golden Beach.
0:05:46 > 0:05:49- She's looking for somewhere - to bury her eggs.
0:05:49 > 0:05:54- We should look for rubbish. - We don't want her choking on a bag.
0:05:54 > 0:05:56- There she is.
0:05:56 > 0:05:58- Look.
0:05:58 > 0:06:00- She's fantastic
0:06:00 > 0:06:02- So elegant.
0:06:05 > 0:06:07- What's she waiting for?
0:06:20 > 0:06:24- I don't think she likes the noise - or the bright lights.
0:06:24 > 0:06:25- You're right.
0:06:25 > 0:06:29- You're right.- - We have to do something.
0:06:29 > 0:06:31- Let's call Dyf.
0:06:31 > 0:06:33- Beth calling Dyf.
0:06:33 > 0:06:34- Beth calling Dyf.- - I'm here.
0:06:35 > 0:06:38- We followed the turtle - to the Golden Beach...
0:06:38 > 0:06:41- ..but she won't venture - onto the beach.
0:06:41 > 0:06:42- There are too many people here.
0:06:42 > 0:06:46- There are too many people here.- - We can't do anything tonight.
0:06:46 > 0:06:48- We'll have to wait - until the morning.
0:06:49 > 0:06:51- Over and out.
0:07:03 > 0:07:04- Are you coming, Sid?
0:07:07 > 0:07:11- Don't worry. He can stay here - to keep an eye on her.
0:07:11 > 0:07:13- See you later.
0:07:17 > 0:07:19- It's quiet over there tonight.
0:07:19 > 0:07:23- The town council has agreed - to close the beach...
0:07:23 > 0:07:26- ..to allow the turtles - to lay their eggs in peace.
0:07:27 > 0:07:29- First, the mother must appear.
0:07:32 > 0:07:35- She's heading for the beach.
0:07:35 > 0:07:39- Keep quiet. Leave her in peace.
0:07:40 > 0:07:43- You're right.
0:07:52 > 0:07:53- What's she doing?
0:07:53 > 0:07:55- What's she doing?- - Making a hole for the eggs.
0:07:56 > 0:07:58- It's incredible.
0:08:07 > 0:08:11- The eggs will hatch - in around two months.
0:08:11 > 0:08:13- This is great.
0:08:14 > 0:08:18- We'll have many more of this - rare species when the eggs hatch.
0:08:18 > 0:08:22- I'm going to keep an eye on them - every day for a month.
0:08:22 > 0:08:24- Hush!
0:08:34 > 0:08:36- What's happening with the eggs?
0:08:37 > 0:08:39- They're starting to hatch.
0:08:39 > 0:08:42- 60 days have passed - since they were laid.
0:08:42 > 0:08:44- That's the hatching period.
0:08:44 > 0:08:48- Since the weather's nice, - there'll be more female turtles.
0:08:52 > 0:08:54- They're hatching.
0:08:56 > 0:08:58- Turtles, ahoy.
0:08:59 > 0:09:01- They're starting to move.
0:09:01 > 0:09:03- It's incredible.
0:09:03 > 0:09:07- I don't believe it. - They're hatching.
0:09:07 > 0:09:10- Shouldn't they be heading - for the sea?
0:09:10 > 0:09:12- What's happening?
0:09:12 > 0:09:17- They're going the wrong way. - They're heading for the town.
0:09:17 > 0:09:21- We have to do something. - What are we going to do?
0:09:22 > 0:09:27- There must be something we can do. - You know more about them than us.
0:09:27 > 0:09:30- Why are they heading for the town?
0:09:30 > 0:09:32- Why are they heading for the town?- - I don't know. I don't know.
0:09:32 > 0:09:36- Is there any way - to attract them this way?
0:09:36 > 0:09:38- OK, OK, I'll think.
0:09:38 > 0:09:42- Wena said they find the water - by using light.
0:09:42 > 0:09:47- They see the moon shining on the - water. They're looking for the moon.
0:09:49 > 0:09:52- There's no moonlight tonight.
0:09:52 > 0:09:55- We have to create our own moonlight.
0:09:55 > 0:09:59- Switch your lights on - and point them at the water.
0:09:59 > 0:10:01- Great idea, Sid.
0:10:04 > 0:10:07- Make them as bright as you can.
0:10:13 > 0:10:16- Is it working? - Are they turning around?
0:10:20 > 0:10:22- Here they come!
0:10:25 > 0:10:29- That was a great idea. Yeah!
0:10:29 > 0:10:30- I agree.
0:10:31 > 0:10:35- I've never been prouder of you, - Captain Sid.
0:10:38 > 0:10:42- Thank you. I'm going to see - if everything's OK.
0:10:45 > 0:10:48- That was an unforgettable - experience.
0:10:48 > 0:10:50- Which is the most unforgettable?
0:10:51 > 0:10:54- The eggs hatching - or Sid becoming a hero?
0:10:54 > 0:10:56- Both are as incredible - as each other.
0:11:26 > 0:11:26- .
