Lampoons of everything from Carrie and ET to Star Wars and Friday the 13th are dragged screaming through this painfully thin comedy starring Kenny Everett and Pamela Stephenson as paranormal researchers investigating Vincent Price's devil-worshipping cult at Headstone Manor. Nothing more than an excuse for Everett and his chums to indulge in low-grade lavatorial humour and fart jokes with gory punchlines, this sad embarrassment makes even the worst Carry On film look like a masterpiece. All done in the best possible taste? Hardly!

Six scientists arrive at the creepy Headstone Manor to investigate a strange phenomena which was the site of a mysterious massacre years earlier where 18 guests were killed in one night. It turns out that the house is the place of a satanic cult lead by a sinister monk who plans to kill the scientists who are inhabiting this house of Satan.
