Death, deception and nature have gone wild, as piranhas protect a stolen emerald cache. Paul Diller (James Franciscus, The Cat o’ Nine Tails) is the mastermind of a multi-million dollar jewel heist. The team, including Robert Lasky (Lee Majors, TV’s The Six Million Dollar Man, The Fall Guy) and his girlfriend, Kate Neville (Karen Black, The Day of the Locust), steal the gems and hurl them to the bottom of Brazil’s deepest lake, which is then filled with deadly man-eating piranha. Soon, all members of the team are pitted against each other in a deadly battle of wits and a deadly battle against piranhas! The all-star cast includes Margeaux Hemingway (Lipstick), Marisa Berenson (Barry Lyndon) and Gary Collins (Hangar 18). Directed by legendary cult director Antonio Margheriti, aka Anthony M. Dawson (The Long Hair of Death).
