This weird, morbid little sci-fi thriller stars Marjorie Eaton as a filthy-rich but decrepit old widow who has devoted much of her wealth to funding the dubious (to say the least) scientific research of Frank Gerstle, who has constructed a mad lab in the widow's basement in order to perfect a technique in which an infusion of atomic energy (or something) will enable him to transfer the widow's brain into a young and sexy physique. To this end, three subjects are solicited through a want ad (under the pretense of employing a housekeeper). The three young women, all of different nationalities (represented by horrendous accents), are subjected to the old woman's scrutiny, until she selects the prime candidate... as the others become fodder for the doctor's pet projects. Needless to say, things don't turn out quite as planned: people are burned, torn apart by man-beasts, and get their eyes ripped out -- one poor lass even winds up with the brain of a cat. This has a certain perverse charm and is competently directed (excepting some boring stretches) by Joseph V. Mascelli -- who, in spite of his work on this film and Ray Dennis Steckler's The Incredibly Strange Creatures Who Stopped Living and Became Mixed-up Zombies, would later publish a well-known book on cinematography.
