The Evil

“Escape is just a nerve-shredding scream for salvation!”

A presence in the old mansion does not want anyone living there, and the people who have just moved in cannot say what it is. Dr. C.J. Arnold (Richard Crenna) and his wife Caroline (Joanna Pettet) have come to turn the house into a rehabilitation center, with Prof. Raymond Guy (Andrew Prine) and others working beside them. Gus Trikonis keeps them inside those dark rooms, and C.J., a psychologist who trusts reason, has to keep explaining what he sees.
