"Somebody is trying to scare us."
A number of scientists and paranormal investigators including Dr Mandeville (Kenny Everett) and Dr Coyle (Pamela Stephenson) arrive at Headstone Manor, on the anniversary of a mass murder there. They have been brought together to investigate some unexplained radioactivity in the area, and soon get caught up with a satanic cult lead by the Sinister Man (Vincent Price).
A spoof that takes in aliens, satanic practices and ghosts along its muddy and unfunny path, unless you favour infrequent, over the top and rather obvious jokes that is.
