When a singer is horribly disfigured in a car accident, a scientist develops a treatment which can restore her beauty by injecting her with a special serum. While performing the procedure, however, he falls in love with her. As the treatment begins to fail, he determines to save her appearance, regardless of how many women he must kill for her sake. Despite the title, this film is really a mad scientist gone madder for a pretty girl. Classic 60's film and worth a watch.
