When bloodthirsty and unstoppable Mikos (George Eastman) miraculously recovers from an accident that should have claimed his life, Sgt. Ben Engleman (Charles Borromel) and a priest (Edmund Purdom) discover that Mikos's indestructibility is the result of a nuclear experiment gone awry. Italian director Joe D'Amato helms this horror slashfest; Annie Belle, Hanja Kochansky, Katya Berger and Kasimir Berger co-star.
