In the 19th Century, a depraved Baron Zorn keeps his two adult children locked up and drugged in his castle, as he fears that they have inherited the curse of his wife's unstable mental illness. His daughter Elizabeth manages to escape, and encounters a young man Carl and spends a short time before she's recaptured. Heading to the castle is doctor Falkenberg to hopefully cure the kids, but Carl who tags along wants to free Elizabeth. Meanwhile hysteria is slowly building in the local village, as there's a sexual predator killing their young woman. They think its demons, but a drifter Priest sees it as his job to rid the area of evil and he points them to Zorn.
Eccentrically ham-fisted and downbeat, but lush looking and skilfully illustrated Hammer Gothic horror period piece that might not have the class of some other Hammer entries, but it sure was entertaining. The negative press might have its reasons, but I didn't find it a complete waste. The psychological story is absurd, glassy and lurid in every aspect, with gratuitous blood letting and excessively pointless nudity equalling extreme blood-lust. However a solid, well-serving cast (featuring Patrick Magee, Paul Jones, Yvonne Mitchell, Gillian Hills and a perfectly impulsive Robert Hardy) and Peter Sykes' pastel, well-etched direction (with inspired strokes and suspenseful fits) counter-pouches its weak, plodding and downright exploitative script of stock arrangement. Striking a big tick to their names were Harry Robinson's sweeping music score of harrowing scope, and Arthur Grant's fluid cinematography of scenic panache. On paper this one got better treatment, than what it really deserved. Fun and trashy Hammer mayhem.
