A Catholic teacher meets an atheist journalist, whom a group of Catholics and Priests believes has been chosen by the devil to be the Antichrist.

A group of Catholics go to a mental institution to perform exorcism in the murderer George Viznik (Brad Greenquist). Father Lareaux (Sir John Hurt), Deacon John Townsend (Elias Koteas), Father Frank Page (Brian Reddy), and the teacher Maya Larkin (Winona Ryder), who was possessed and exorcised in the past, unsuccessfully try to exorcise the man and Father Lareaux is deeply affected and falls into a coma. Maya brings the Viznik's coded writings and after deciphering it, she concludes that the writer Peter Kelson (Ben Chaplin) might be the Antichrist to be incarnated by Satan. She seeks him out but the atheist Peter, who has been raised by his uncle Father James (Philip Baker Hall), does not believe in her. But when strange things happen to him, Peter meets Maya and they investigate together the chance to save his soul.—Claudio Carvalho, Rio de Janeiro, Brazil

A small group of Catholics led by an ailing Priest believe that Satan intends to become man, just as God did in the person of Jesus. The writings of a possessed mental patient lead them to Peter Kelson (Ben Chaplin), a writer who studies serial killers. They think it's his body Satan will occupy. The youngest in the group, a teacher named Maya Larkin (Winona Ryder), goes to Peter to investigate further and to convince him to believe in the possibility of Evil incarnate. Other signs come to him as he and Maya them take a journey full of strange occurrences, self-discovery, and an ultimate showdown.—<[email protected]>
