Just a bloody stump

In Bermuda, two amateur treasure-hunting divers inadvertently discover the secret cargo of a World War II shipwreck and conflict with treasure hunters. Not one of the greatest classic seventies films, but surprisingly entertaining and exciting still. Starring Nick Nolte, Jacqueline Bisset, Robert Shaw and Eli Wallach, written by Peter Benchley (Jaws), directed by Peter Yates (Bullitt).
