When the police forcibly clear out a shantytown Father Anton Jonascu, who is there with his colleague Father John Royce distributing sandwiches and blankets, sees a demon the a policeman's face. Jonascu has been struggling with what he sees as the futility of their good works, and he has been thinking of asking his superior for a reassignment. His physician Dr. Pallas informs him that he has an inoperable brain tumor which likely explains the strange visions he's been having. He is not the only one who saw the demon face however and a street person, Carlito, says he saw them too. Dr. Pallas eventually reveals these "demons" are actually messengers who bring with them the gift of healing leaving Jonascu with a major decision.
