He sees ominous figures and two dogs fight visciously nearby, setting the tone for the rest of the film.Father Philip Lamont Richard Burton, who is struggling with his faith, is assigned by the Cardinal Paul Henreid to investigate the death of Father Lankester Merrin Max von Sydow. Merrin was killed in the first film during the exorcism of Regan MacNeil Linda Blair. The Cardinal informs Lamont who has had some experience at exorcism, and has been exposed to Merrins teachings that Merrin is being investigated posthumously for heresy. Despite approval of the McNeil exorcism by a bishop, the Church is no longer convinced that McNeil was truly possessed, and the controversial nature of Merrins books on the subject are being reconsidered as politically and theologically suspect. ........
