A grieving mother heads for the sun-kissed Caribbean to try to discover what killed her son. Unexpectedly, she learns mutant carnivorous fish are responsible - and a teeming mass of the scaly critters are still lurking in the area, waiting to prey on anyone foolish enough to venture to the water's edge. Horror sequel from director James Cameron, starring Lance Henriksen, Tricia O'Neil, Leslie Graves and Steve Marachuk.

A scuba diving instructor, her biochemist boyfriend, and her police chief ex-husband try to link a series of bizarre deaths to a mutant strain of piranha fish whose lair is a sunken freighter ship off a Caribbean island resort.
