The fifth appearance of Paul Naschy's burly werewolf character Waldemar Daninsky (following Frankenstein's Bloody Terror), this film finds Waldemar returning home from Tibet, where he was first afflicted with his beastly curse. After making cutlets of his cheating wife and her lover, he is accidentally killed, then brought back to life by a sadistic lady scientist (Perla Cristal) who likes to beat him savagely and keeps her less fortunate subjects' severed body parts strewn about the house. Waldemar eventually escapes the laboratory to slay a few local kids before coming face-to-face with his late wife, who has also been transformed into a werewolf by Cristal.
