7

Black Orchid releases an alien fish into the waters around Ocean Storm. They seem attracted to the toughened steel alloy from which the submarine's hull is made. The Automated Construction Plant builds a fish of its own made from the same material but containing an explosive. This mechanical fish is named Ocean Diner. The alien fish are lured away from the Ocean Storm by Ocean Diner but when it fails to explode Sam must risk his life by swimming to the mechanical fish to repair the explosive charge. The alien fish attack Sam but he succeeds in his mission and the alien fish are destroyed. (Source: Enoki Films)
