While delivering supplies to an isolated island, a hurricane forces Captain Thorne Sherman and his first mate Rook to take shelter with the scientists working there. The storm, however, is the least of their worries. The experiments conducted by Dr. Craigis and his team have created a horde of monstrous creatures which have broken loose and are stripping the island of all life to feed their ravenous hunger. Even if Thorne and the others manage to survive the hurricane, to get off the island alive, they will have to face the onslaught of...THE KILLER SHREWS!
