Jonathan Steel has no past. Three years ago, a psychopathic killer possessed by the "thirteenth" demon destroyed his life. Now, he searches the countryside for the hideous creature.
For over six weeks, no one has entered the Lakeside Community Church in Louisiana. After a deacon's gruesome death, an evil presence has taken over the church, beginning a terrifying chain of events. Strange writing on the walls, blood-soaked floors, and red-eyed spiders have all appeared in the sanctuary in a matter of days.
This shadow of evil stretches over the lives of Reverend Thomas Parker and his wife. Because of the evil permeating his church, his congregation has been lost, and his own marriage now stands in jeopardy. Seeking Jonathan Steel's help, Parker yearns to free his church and his small community from the clutches of this evil being.
Steel assembles a team to combat the demon and discovers more of his own sordid past. Was he called to Lakeside to help someone in distress, or does he seek revenge against the heinous "thirteenth" demon? As Steel races to the aid of Reverend Parker, he is the center of a final confrontation with a mysterious man from his past who serves the "thirteenth" demon.
