Season 1

Caught in the middle of the two priests is the Rance family, who are members of Tomas' parish. On the surface, they're a normal, American family, but all is not as it seems in this household. The patriarch, Henry Rance, is recovering from a traumatic injury. Eldest daughter Katherine has become a recluse who refuses to leave her room. Her younger sister, Casey, thinks she's hearing strange noises coming from inside the walls. And mother Angela believes there is something in the house, a demonic presence, growing stronger by the day. Desperate, she begs Father Tomas for help, unwittingly setting the naïve young priest on a collision course with Father Marcus. Separately, each faces an insurmountable task, but together they become the Rances' only hope against an evil force that has been mobilizing for centuries.
