Lost Souls

Years ago, priests exorcised a demon out of young Maya Larkin (Winona Ryder). Now she uses her unusual sensitivity to the same demons who once came after her to help the priests in other exorcisms. In one such case, a serial killer named Henry Birdson (John Diehl) claims to know the name of a man who will soon be possessed by Satan, beginning a reign of evil over the world. Maya discovers that the man in question is Peter Kelson (Ben Chaplin), an author of true-crime books who has both wealth and fame but no religious faith. At first Peter is skeptical, but a series of strange and mysterious clues indicates that he might indeed be the victim of a massive satanic conspiracy. Maya and Peter must work together to learn how to reverse what has already begun before time runs out. (official distributor synopsis)
