In 19th Century Europe, Professor Mayer (Boris Karloff) perfects an atomic ray machine, an early example of nuclear fusion. Aliens find out about it, and send a spacehsip down to destroy the technology before it runs amok. They take over the mind of a local serial killer, Thomas (Yerve Beirute) as well as Professor Mayer's, and the alien-controlled pair start then begin their plans to destroy the whole town via an explosion of the machine. The trouble is, even under alien control, poor Thomas gets very distracted unless he kills women on a regular basis, so the head alien (Sergio Klein) has to keep sending him fresh women to murder, including his own girlfriend (Tere Valez). Attractive Christine Linder is Mayer's daughter, Laura. Enrique Guzman plays her smug scientist boyfriend, and Maura Monti is Mayer's buxom, hideously scarred assistant. All the girls have to tangle with the homicidal Thomas sooner or later, as the irate villagers start closing in, and the aliens get ready to make their move. This Mexican-English production was one of Karloff's last films. Also known as "Alien Terror."
