An important scientific experiment goes horribly wrong, a leading researcher is left dead, and another is missing. While detectives investigate the accident, innocent people are being horribly mutilated. Can science resolve the problem that science has created? Only the remaining Ross twins, Karl and Hank, with the help of the detectives, and Susan, daughter of the missing man, have the answer. But will they be too late? Monsters, stock footage, bad acting, repetitive dialogue, and static direction combine in a tribute to fifties sci-fi-horror, in two hundred and forty seconds.
