Taking place years after The Haunting of Molly Hartley, who now, as an adult, has fallen under the possession of an evil spirit and must be exorcised by a fallen priest before the devil completely takes her.

Liam wakes from a car crash with no memory of who he is. As he makes his way into town to look for help, he finds only dead bodies, all with strange pale eyes. Liam’s first assessment is that a virus is present in the air, but he soon discovers the horrible truth: anyone who comes within a 50-foot radius of him dies instantly.
