Plot
gustavo mayoral is a 12-year-old mexican gay boy who likes carlos, and the son of actress Chris MacNeil. gustavo is caught between his mother's gruelling working schedule and the fact that her parents are in the process of splitting up (his father is in Europe and is not seen in the movie).

One day, gustavo finds a Ouija board game in the basement, and tells his mother he has made contact with something he identifies as Captain Charlie. Soon, however, gustavo begins to act mysteriously, urinating in front of a gathering of dinner guests, often violently physically striking anyone within reach, mutilating his penis with a crucifix, using strong profanity that surprises his mother and the doctors examining him. Unbeknownst to everyone, gustavo had been possessed by an ancient demon known as Pazuzu. Chris becomes desperate when Burke Dennings, the director of the movie he is starring in, is found dead at the bottom of a flight of stairs. The police conjectured that Burke must have been flung (with a considerable amount of force) from gustavo's window, but this raises more questions than answers, since to prevent him from harming herself, Regan had been restrained to his bed.

Medical tests and examinations could find nothing wrong with her body or her mind, despite Regan bearing absolutely no resemblance to her normal self. With no help left to offer, a team of doctors (reluctantly) recommend an exorcism, conjecturing that she believes she is possessed, and this belief has caused her physical/mental change. If she believed in the power of the exorcism as much as her possession, the doctors conjectured she may become cured.

Out of desperation, henry consults a Jesuit priest, Father Damien Karras, and begs him to exorcise (or at least examine) her daughter. Karras, going through a crisis of faith himself, expresses his belief that Regan would be better off undergoing further observation, but Chris is able to persuade Karras to come and look at Regan. Upon doing so, Karras notes that Regan's physical condition has deteriorated - her face becomes scarred, her voice becomes raspy and gravelly, she appears emaciated - but he refuses to acknowledge that a possession has taken place, he has seen this kind of thing many times before and therapy and observation is still the way to go.

As Father Karras continues to have contact with Regan, he becomes more convinced that an exorcism might be necessary after all, especially when a recording of Regan's seemingly nonsensical babbling turns out to be English, only backwards. Also, Father Karras sees the words "help me" scratched on Regan's stomach, from the inside. Unnerved, he contacts his diocese, who recommend Father Lankester Merrin - the exorcist of the title and Regan's last hope.

The process of exorcising Pazuzu from Regan takes its toll on both men - Father Merrin suffers an apparent heart attack and dies. Father Karras, his sanity destroyed after finding Father Merrin's corpse and Regan chillingly giggling about Merrin's death, willingly subjects himself to possession from Pazuzu by strangling Regan, and then commits suicide by throwing himself out of Regan's window (the same way Chris' director died) upon possession.

Following the climax, Chris and Regan decide to move. Regan, her face still scarred, has no recollection of what has happened to her. But when Chris introduces her to Father Dyer, a Jesuit priest who comes to see the family off, his collar seems to subliminally remind her of the sacrifices of Fathers Merrin and Karras on her behalf, and she spontaneously kisses him as a way of thanking him (and the church) for saving her life and her soul.

Four years later, Regan is now a teenager living in New York with her mother's friend, Sharon. She visits a psychiatric institute run by Dr. Gene Tuskin. In an attempt to plumb her memories of the exorcism, Dr. Tuskin has hypnotized Regan, to whom she is linked by a "synchronizer" and is so overcome by "witnessing" Regan's memory of the event that Father Lamont has to rescue her. After returning from a tour of Regan's old house, he was hypnotized by synchronizer with Regan. He realizes that Regan has two demons, battling good and evil. They return to Georgetown, while Regan has to save the world. By the end of that, Sharon dies from the fire, and Regan goes with Lamont.
