A family's Long Island dream home becomes a horrific nightmare in this chilling tale, supposedly based on a true story. The brutal murder of six people just one year previous causes the new tenants (James Brolin and Margot Kidder) some restless nights, to say the least. Ooze comes out of the walls, doors mysteriously and violently swing open, and flies descend. Soon priests (including Rod Steiger) are called in to exorcise the house, but even they may not be able to stop the unexplained occurrences.
