The Exorcist - All Seasons

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.

Season 2 picks up with Father Tomas Ortega and a newly collarless Marcus Keane out of Chicago and on the road, searching out evil. Across the Atlantic, Father Bennett attempts to weed out those within the Vatican who have turned against God. Ultimately, Tomas and Marcus are led to Andrew Kim, a former child psychologist who runs a group home for five at-risk foster children on a secluded private island off the coast of Seattle. When one of the children under Andrew's care is targeted by a powerful force, the two priests head west, setting themselves on a collision course with hell.
