DEADLY BLESSING

Martha and Jim Schmidt live on an isolated Pennsylvania farm named "Our Blessing." Most of their neighbors are "Hittites", an austere religious community led by Jim's father Isaiah Schmidt who forbids any interaction with non-Hittites. After breaking up a fight between one Hittite member, William Gluntz, and another, more artistically minded neighbor, Faith Stohler, Jim finds "incubus" scrawled on the wall of his barn. Later that night, Jim is killed when his tractor suddenly starts up and crushes him against the wall. Isaiah and other Hittites observe Jim's funeral, as he was a lapsed member of their community; they consider Martha to be an incubus for having lured him away from their religion.

Martha's friends Lana Marcus and Vicky Anderson visit the farm, hoping to persuade her to return to Los Angeles. While creeping around Our Blessing at night, William is stabbed in the back by a black-dressed figure. The following day, while looking for William, Isaiah offers to buy the farm from Martha, but she angrily refuses. Lana is nearly trapped in the barn by the black-dressed figure. As she escapes, she finds William's corpse hanging from a rope. The Sheriff advises the three friends to leave town, as someone may be after them. However, they decide to stay. When Isaiah finds out that Jim's brother John has been seeing Vicky, he beats then exiles him. John meets Vicky outside the cinema and she lets John drive her car, giving him a sense of freedom. They stop at the side of a road and begin to make out but they are killed by the black-dressed figure.

Lana, overwhelmed by disturbing dreams, begins to believe that death is pursuing her. Martha discovers that Jim's grave has been dug up and the casket filled with chickens from the Stohlers' farm. In their barn, she finds Jim's body and an altar to her. John's estranged fiancée Melissa arrives reciting a ritual of exorcism but is attacked by Faith's mother, Louisa. Faith and Louisa, who hate the Hittites, have been the black-dressed figures murdering them. Martha struggles with them and tears open Faith's shirt, revealing her to be a man who has been in love with Martha. They pursue Martha to Our Blessing. There, Lana kills Louisa and a late-arriving Melissa stabs Faith to death. In a religious fervor, Melissa threatens Martha next, but an even-more-late-arriving Isaiah assures her that the messenger of the incubus has already been killed.

The day after, Lana returns to Los Angeles. Though Jim's ghost tries to warn her, the incubus bursts through the floor and drags Martha to hell.
