A watery Blair Witch-style project, it's about a couple of scuba divers who get separated from the rest of their diving party and are left behind by their boat. Fifteen miles from land. One million square miles of water.
No-one knows they are missing.
You get the picture. Enter fish with sharp teeth. And, in this case, the teeth were very much the real thing. Blood was shed in the making of this movie. Celebrities emerging from the preview (Johnny Vaughan, for instance) said they'd been terrified. Zeitgeist's verdict is: anything that terrifies Vaughan is all right by us.
