Eric Forsberg writes and directs this B-movie sci-fi horror. When a team of Venezuelan scientists genetically mutate the already fearsome piranha fish, the resulting creatures escape into a nearby river and immediately start to breed and grow at a terrifying rate. Before long they are leaping into the air and destroying helicopters, crashing into hotels and eating battleships. Can pumped up, superhuman, martial arts master Jason Fitch (Paul Logan) stop the giant predators before they devour the whole of Florida? 1980s pop siren Tiffany co-stars.
