As a U.S. Navy destroyer cruises near Guadalcanal in the South Pacific, its sonar detects muted but constant hammering on metal undersea. The eerie sounds emanate from a submarine on the ocean floor, apparently there since World War II. The ship's chief boatswain's mate becomes very nervous, having served aboard that sub - and he was its sole survivor.
