Jacinto Molina, best known as "Paul Naschy," returned in his eighth go-round as the tortured werewolf Waldemar Daninsky in this odd variation on the theme. Daninsky joins an expedition to Tibet in search of the Yeti, only to be bitten by two cannibalistic women whom he made love with in a cave. That turns him into the wolf-man, but he spends most of the running time defeating bandits and the despotic Saga Khan, only fighting the Yeti briefly in the film's closing moments. This disappointment was Molina's last appearance as Daninsky for five years.
