00:03The engines are running. Why have we stopped?
00:15That's not a reef. It's moving!
00:21What on earth is that?
00:31There are two signals. The second one's much deeper.
00:43Is that thing coming here?
00:45Yes, but something's wrong.
00:50Look behind it!
00:54What?
00:55It's running away.
00:56What?
00:57Running away.
01:06The sonar can't find its end.
01:11The larger signal disappeared.
01:13Where did it go?
01:15Under the continental shelf.
01:22It stopped at the harbor. Why would it stop there?
01:36It moved between the boat and the wave.
01:40Close the harbor gates.
01:43Wait! You'll trap it inside.
01:46Then what do you suggest?
01:49Three flashes. Over and over.
01:53What does that mean?
01:55I think it's a warning.
02:03That's beneath the harbor?
02:05Yes. And something's moving through it.
02:11Where's the second signal?
02:13It is right beneath the harbor.
02:16And it is moving toward the city!
02:24Why is the current reversing?
02:27Something below is pulling the water.
02:31It pushed us clear.
02:35Three calls, then a reply.
02:35Why would it save us?
02:46Three calls, then a reply.
02:48From the larger creature?
02:52The pressure spike is at Pier 6.
02:55Evacuate Pier 6, immediately.
03:01Three flashes again.
03:05It's calling to something.
03:11Was that an echo?
03:13No. Something answered from Pier 6.
03:26Pier 6 is lifting.
03:28Clear the waterfront.
03:36That boat can't get out.
03:38Get them clear. Now.
03:43It's protecting the boat.
03:54That reply isn't an animal.
03:57Then what is it?
03:58A machine.
04:01What are we looking at?
04:03A door.
04:05900 meters down.
04:14Something's hitting it.
04:15From the other side.
04:21The lock is opening!
04:24Can we stop it?
04:25Not from here.
04:33What's causing those pulses?
04:36Something behind the door.
04:41Something's looking back.
04:45Get the drone away.
04:51The entire harbor is shaking!
04:54The pressure's coming from below.
05:00The Leviathan isn't calling it.
05:05Then what is it doing?
05:07Trying to seal the door.
05:13Our drilling conduit broke the lock.
05:16We opened that thing?
05:21Drilling power is off.
05:24The lock's still moving!
05:31It's going back to face it.
05:42It's coming through!
05:44The Leviathan can't hold it alone!
05:54The lock needs a third signal.
05:57Can we generate it?
05:58With the research drone.
06:01Is the drone in position?
06:03Yes.
06:05Sending the reset signal.
06:12It's answering us!
06:15The lock is closing!
06:24It's forcing the gate open again!
06:33The Leviathan is in the gate.
06:36If it closes, it'll crush her.
06:46Pull away!
06:47Please!
06:48It isn't moving!
06:55Pull away!
06:57Please!
06:58It isn't moving!
07:01Move!
07:02Please!
07:03Move!
07:11I'm stopping the lock!
07:13That thing could escape!
07:15Give her five seconds!
07:27She's clear!
07:28She's clear!
07:32Is it sealed?
07:33Yes.
07:34The lock is holding.
07:45Was it trying to attack us?
07:47We opened its prison.
07:51We thought she came to destroy us.
07:55She came to protect us.
08:05What are those?
08:07Other doors.
08:08That doers!
08:08I but to wash...
08:09I...
