Three excommunicated nuns, Nora, Agnes, and Celeste, join a paranormal unit sanctioned by the Catholic Church, in the hopes for redemption in God's eyes. As empaths, their jobs are to verify reports of demonic possession, and when their boss, Father MacLeod, is persuaded to investigate a house in a small New Hampshire town, the three women are chosen to assess these claims. Goffstown police files detail numerous extraordinary occurrences at the Moore house, including seven gruesome, unsolved killings. For this reason, the three empaths are instructed to not enter the dwelling, but to employ their abilities while circling outside the house. Nora, Agnes, and Celeste proclaim it free of supernatural forces, but they are wrong...dead wrong.
The three women discover their presence is part of a larger plan. The Moore House is not only possessed, but it soon possesses them, forcing them to relive the sins that had resulted in their excommunications. Their belief in God and redemption dissolving, they become pawns in a demonic scheme, a means to an end, in which Father MacLeod is their only hope. But Father MacLeod has made his own deal with devil, and the devil is ready to collect.
