In response to a global rise in demonic possessions, the Catholic Church reopens exorcism schools to train priests in the Rite of Exorcism. On this spiritual battlefield, an unlikely warrior rises: a young nun, Sister Ann (Jacqueline Byers). Although nuns are forbidden to perform exorcisms, a professor (Colin Salmon) recognizes Sister Ann’s gifts and agrees to train her. Thrust onto the spiritual frontline with fellow student Father Dante (Christian Navarro), Sister Ann finds herself in a battle for the soul of a young girl, and soon realizes the Devil has her right where he wants her….and it wants in.
