By the time you run, there is no escape.
When you think you're free, you might be dead.
By the time you learn the truth ... it may be too late.
A psychologist (Richard Crenna) and his wife (Joanna Pettet) buy a dilapidated historical mansion with a dark past in this terrifying chiller. Hoping to restore the estate and turn it into a drug rehabilitation clinic, he accepts the help of some of his students and current patients. But when a secret door in the basement of the house is opened, the malevolent presence within is unleashed, trapping everyone inside. One by one, they are picked off by the unspeakable terror that has awoken ... and the doctor learns that even though his name is on the deed, the house belongs soul-ly to The Evil. Victor Buono, Andrew Prine, and Cassie Yates also star.
