The Slaughter (2006)

Synopsis
In the tradition of the Evil Dead series comes this occult horror comedy from director Jay Lee. When a group of college students take a job cleaning an old house, they expect little more than a few extra bucks in their pockets. But when they discover an ancient book of spells, they get far more than they bargained for. Before long, an unspeakable evil is unleashed and the bodies begin to pile up. ~ Matthew Tobey, All Movie Guide
