Sent to Africa at the close of World War II to tend to the needs of the local community, Father Lankester Merrin (Stellan Skarsgard) gets more than he ever bargained for when he has his first brush with a devilish force known simply as Pazuzu. Director Renny Harlin traces the roots of evil in this prequel to the 1973 box office smash. Izabella Scorupco, James D'Arcy and Ben Cross co-star.
