خلاصه داستان : سالها قبل از اینکه پدر لنکستر مرین به نجات روح ریگان مک نیل کمک کند ، او ابتدا با شیطان Pazuzu در آفریقای شرقی روبرو می شود. نبرد اولیه مرین با پازوزو منجر به کشف مجدد ایمان وی می شود.

Haunted by terrible acts the Nazis forced him to participate in, the disenchanted Father Lankester Merrin focuses his energies on helping with an archaeological dig in the northern part of Kenya. There, the crew uncovers a church that predates Christian missions into the area, but the discovery also causes strange events to start occurring -- including physical changes to a young, disabled boy, whom Merrin grows to suspect has been possessed by a demon.
