This British horror spoof was conceived as a star vehicle for then-popular TV comedian Kenny Everett, who plays an occult scientist whose team of paranormal researchers are measuring psychic disturbances at a rural English estate called "Headstone Manor." Once the site of a bloody massacre, the house is haunted by the very real presence of a moronic devil-worshipping coven and their exasperated leader, "The Sinister Man" (Vincent Price, who seems to enjoy serving up the ham). The inept Satanists are determined to prevent the so-called psychic experts from completing their task. Despite a few clever gags and some very funny asides from the mugging Price, viewers expecting a Monty Python-style satire of horror films will be rather disappointed.
