This poorly scripted horror film about miniature, finny jaws details the mating rituals of the fictional grunion fish (falsely introduced as piranhas for more box-office recognition) and their need to attack and kill humans -- either inside or outside the water. These saber-toothed wonders have been hatched from a canister of eggs on a sunken ship in front of a posh Club Med resort, which features the mating rituals of humans who at times need to attack and kill fish. The product of a series of secret genetic engineering experiments, the toothy fish are to be tracked down by an undercover biochemist (Steve Marachuk), who is soon joined by the resident scuba diver at the resort (Tricia ONeil). With believable gore but second-rate special effects, this film in no way presages the coming success of its debut director, James Cameron. ~ Eleanor Mannikka, All Movie Guide
