room, Tristen sees a young girl walking backward. After she is discharged, the group retreats to Jeff's home, an industrial building that was once a factory. While Tristen rests, the group reviews Jeff's tapes, which uncover an image of Erica circling around a tree, nude. Distraught, Erica claims she has no memory of such an event and goes to pray in another room. When Kim tries to console her, Erica reveals rash-like symbols covering her body and proclaims the group has been marked for death. Kim borrows Jeff's van to pick up coffee and alcohol in town. At the country store, she gets into an argument with the cashier. While driving away, she swerves to avoid a group of children in the road and crashes the van into a tree, denting the fender.

The three follow Tristen to the second floor, where she ties a rope around her neck and taunts Stephen, daring him to push her. In a fit of rage, he pushes
