The Evil (1978)

A psychologist buys an old mansion at a bargain price and asks a colleague and his students to help him fix it up. Things are fine until a cross is removed from a stone door in the basement and satan himself starts reaking havok on each person one by one. Their only hope of ever leaving alive or dead is the ghostly resident that built the house.

The Evil is a horror movie featuring Richard Crenna and directed by Gus Trikonis.
