Mark Damon (who was in a bunch of spaghetti westerns) plays an 18th century scholar who believes he's found the ring of the Nibelungen, probably named after the Wagner opera, which holds great power, conveniently located at Castle Dracula. His gambling twin brother takes off before him, and naturally finds a countess who invites him to dine. Later that night, the more scholarly of the brothers arrives. Coincidently, it's the Night of the Virgin Moon, a night that falls every fifty years and draws five virgins from the surrounding village to the castle not be heard from again. Our hero sets out to protect his brother, find the ring, and rescue any of the women, who naturally disrobe for the festivities.I don’t know what can say about this movie, since everything you would like to know about it is right there on the small synopsis. It’s your typical European gothic horror movie trying to cash in on the Hammer horror craze, which was also going down by this time. It’s a very old-fashioned scarefest that also happens to have it’s fair share of horror and sex. The performances are rather ho-hum, although I have to give a lot of love to Rosalba Neri, the most perverted and brave actress of the European horror scene during the early 70’s. In movies like this one, Lady Frankenstein and Slaughter Hotel (where we get to see her masturbate full-frontal, yay!), Neri goes completely for the gold, giving an uninhibited sexual performance that makes the hairs of any men and women stand up in admiration.
Other than the sex, I really liked the gothic atmosphere in the film. But other than these two things, there’s not much to recommend here. It comes and goes, just like taking a dump. You live it while you drop it, but after that, you just flush it down the toilet.
