Perched on the hull of a wrecked Soviet freighter, a team of deep-sea miners (including Hector Elizondo, Ernie Hudson and Daniel Stern) -- led by head oceanographer Steven Beck (Peter Weller) -- comes face to face with a mutant creature that's the product of a failed genetic experiment. As Beck's crew members begin to disappear one by one, the flesh-eating monster lurks below the surface -- and the divers left alive are scared to death.
