Something is wrong in the Rance household. Angela Rance (Academy Award winner Geena Davis, "A League of Their Own", "The Fly") suspects demonic possession and enlists the help of two priests: the progressive, but naive, Father Tomas Ortega (Alfonso Herrera, "Sense8") and the broken holy warrior, Father Marcus Keane (Ben Daniels, "Flesh and Bone", "House of Cards"). Together, they will be drawn into a nightmare beyond imagining.
