Two women tourists are kidnapped and wake up in a scenic castle (filmed on location) inhabited by opium smoking lesbian vamps (& obligatory dwarf). If the women sell their souls to Morgana they can live a life of beauty & pleasure, if not they must join the old crones in the dungeon. If you are looking for erotic horror you will be disappointed by this; despite the Gothic psychedelia trappings, it's a rather downbeat cold-looking film and (if you care!) the would-be sex scenes were badly cut by the censor. However, it's well made in the slow dreamy surreal manner associated with Jean Rollin (actually it's a lot more accomplished than the average Rollin film). And there are some good scenes & images and interesting themes to do with beauty & age. It's also possible the whole thing is some kind of Cocteau-like allegory for the opium life. If you can find the menu on this Pagan DVD edition, you'll find as an extra a very informative essay from Pete Tombs giving a lot of context to the production & its director, which greatly helps in appreciating this rather obscure (in every sense) movie.
