Acting as his father’s successor, Cotton not only performs rousing Sunday morning sermons, he performs the occasional exorcism as well. What Cotton’s family doesn’t know (and what Cotton decides to share with a documentary film crew) is that his faith is waning, and before retiring, he hopes to reveal the sham of the modern exorcism. With film crew in tow, Cotton heads to Louisiana, to the Sweetzer farm, where he meets Nell…and encounters more than he bargained for.
