Nolan Mack, a soft-spoken bank employee, undoubtedly loves his wife Joy, though their cavernous empty house only underscores how disconnected they’ve always been from each other. Nolan finds himself drifting from his familiar present-day life in pursuit of lost time after meeting a troubled young man named Leo on his drive home. What begins as an aimless drive down an unfamiliar street turns into a life-altering series of events.

After years of performing “exorcisms” and taking believers’ money, Reverend Marcus travels to rural Louisiana with a film crew so he can dispel what he believes is the myth of demonic possession. The dynamic reverend is certain that this will be another routine “exorcism” on a disturbed religious fanatic but instead comes upon the blood-soaked farm of the Sweetzer family and a true evil he would have never thought imaginable.
