This is actually more a Spanish horror movie than an Italian one (so it's really more "paella horror" than "spaghetti horror"). I'm sure there was probably Italian co-production money involved, and the cut I saw was obviously not a Spanish one (since it had some brief nudity). But most of the cast was Spanish except for the Austrian actress Krista Nell, who was usually relegated to supporting roles but acquits herself well here as the lead. She plays a woman whose sister has gone around the bend after accidentally becoming involved with a satanic cult, so for some reason she tries infiltrate the same cult with not much better results.
As far as the plot goes, the movie is pretty weak. The directorial style doesn't begin to approach either the best Italian horror/gialli films or the British Hammer films, but it's not bad for early Spanish horror, and this is one of the few Spanish films that could actually be described as "psychedlic" in places (Spain's dictator at the time, Francisco Franco, had little use for the kind of decadence sweeping the rest of Europe that period, but, hey, if it's a bunch of satanists doing it. . .). The acting in general is unremarkable, but Nell and Teresa Gimpera, who plays the jealous girlfriend of the cult leader, are better than average. This is one of those movies I wouldn't look to hard for, but it's worth watching if you somehow run across it.
