A gang of jewel thieves steals a fortune in emeralds from a Brazilian mine but must hide the gems at the bottom of a lake to be recovered later. Unbeknownst to them, the lake is full of razor-toothed, flesh-eating piranha, and it's not long before the crooks and some guests at a nearby resort are turned into so much chum. Lee Majors, Karen Black, Margaux Hemingway, James Franciscus, and Marisa Berenson star in this blood-soaked aqua-shocker. 100 min. Widescreen (Enhanced); Soundtrack: English mono; interview; theatrical trailer.
