Werewolf Waldemar Daninsky travels from his native Europe to Japan seeking a cure for the lycanthrope curse inflicted up him and his family by a 16th Century witch. A Jewish scientist in Spain tells him to seek the help of a Samurai named Kian who can cure him with a special sword. So, Waldemar goes to Japan with his lover and a blind servant girl. Once settled in the land of the rising sun, he goes on a murderous rampage every time the moon is full. The samurai eventually finds Waldermar and tries to administer a cure with drugs, a Tibetan flower and the aforementioned sword.

This movie - like many others during Naschy's most prolific career - was initially shot in two different versions: 'Mainstream' and 'Adult.' Traditionally, the adult prints are much more difficult to find. [For other Adult Versions, also see DR JEKYLL AND THE WOLFMAN, THE WOLFMAN NEVER SLEEPS, NIGHT OF THE HOWLING BEAST, COUNT DRACULA'S GREAT LOVE, et al]. In the early 2000s, Paul Naschy went to Hollywood for two movies: Fred Olen Ray's TOMB OF THE WEREWOLF and COUNTESS DRACULA'S ORGY OF BLOOD. He then flew to Brazil for Ivan Cardoso's tailor-made WEREWOLF IN THE AMAZON. That would be his final motion picture. Paul Naschy died of pancreatic cancer at age 75 in 2009.
