Summary:One of nature's most powerful creatures just got a whole lot hungrier in this action thriller. A collision between alien spacecraft sends strange debris hurtling into the Pacific Ocean not far from an undersea scientific research station, which is manned by oceanographer Mike (Corin Nemec), his wife, Linda (Vanessa Angel), and naval supervisor Captain Riley (Corbin Bernsen). The alien matter has a strange effect on the great white sharks who live in the area; already powerful predators, soon the sharks develop a voracious taste for human flesh, and begin attacking Navy divers, with an eye on Mike, Linda, and Riley as his next entrées.
