A bright but meek salesman, drowning in debt as he’s about to get married, receives a mysterious phone call informing him that he’s on a hidden camera game show where he must execute 13 tasks to receive a multi-million dollar cash prize.

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.
