“It's Turning the Beach ... Into a Buffet!”

Ned Turner (John Huston) is a reporter who starts keeping a list as people vanish from the water near a seaside town. The bodies that turn up are stripped to the bone, the marrow gone too, and no scientist can name an animal that does that. Ovidio G. Assonitis stages the attacks in grainy daylight, with the waves doing most of the frightening.
