The title here is somewhat deceptive. The yeti vs. werewolf battle you would expect is just tacked on to the end. Most of the movie is about a Himalayan warlord who keeps slave girls as a means of curing his bacne. A scientific yeti expedition gets ensnared by the bandits. Meanwhile, Paul Naschy gets ensnared by demon cave girls and subsequently werewolfed by them. Parts of this crazy plot work, others fall flat under the cheapness of the location and the production.
