Psychologist Peter Bower's life is thrown into turmoil when he discovers that the patients he has been seeing are ghosts. Risking his own sanity, Peter delves into his past to uncover a terrifying secret which only he can put right. Backtrack is a spine-chilling story from the acclaimed writer-director, Michael Petroni.

Dr. Gene Tuskin works with troubled children, perhaps none more troubled than Regan MacNeil, who suffers from bad dreams and repressed memories. The memories she represses are of the time she was possessed by a demon. Dr. Tuskin's invention, a device that hypnotizes two persons and links their minds together, reveals that the demon, named Pazuzu, still lurks within her. It is desperate to emerge again and wreak havoc. Meanwhile, Father Philip Lamont is ordered by his cardinal to investigate the death of Father Merrin, the priest who died while performing an exorcism on Regan. Father Lamont undertakes his task reluctantly. He feels unworthy of his assignment. He also feels that Evil is literally an entity and that this entity is winning the battle over Good. His investigation takes him to Africa where he locates another recipient of Merrin's exorcising and learns something fascinating and terrible about locusts.
