Something is wrong with Leila (Grace Mills) and Father Adrian Dunning (Paul Naschy) is called in to evaluate the situation.
Some may call this a ripoff of The Exorcist with Linda Blair, but I'd rather see the flesh displayed here than some special effects. The fact is that The Exorcist was not seen in Spain before this film came out.
Anyway, it's a Paul Naschy film, and I am a completest.
You won't see amazing special effects, because they didn't exist. So it looks fake at times, but it was a good story and an interesting film.
Paul Naschy stole the show. I wasn't his finest hour, but he was head and shoulders above the rest. The makeup was good, and one could ignore how the film seemed to go all over the place just to see Naschy.
