American gun smuggler Reynolds, stranded in a tiny seaport in Africa, joins the crew of a marine biologist's boat. He soon discovers the boat's owner and his wife are trying to retrieve gold bullion that lies deep in shark-infested waters. Typical Reynoldsian action-infested dumbness. Like "Twilight Zone: The Movie," earned notoriety because of on-location tragedy: a stunt diver really was killed by a shark. Edited without the consent of Fuller, who disowned it.
