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.
