The short version
The Exorcist follows actor Chris MacNeil as her daughter Regan begins suffering violent, unexplained changes in behavior and body. Medical explanations fail, and the disturbance grows into something that appears supernatural. Father Damien Karras, a priest and psychiatrist struggling with guilt over his mother's death and doubt about his faith, is asked to examine the case. Evidence pushes him toward the possibility of possession, and experienced exorcist Father Merrin is called in. The ritual becomes a direct confrontation with the demon using Regan's body. Merrin dies during the ordeal, and Karras sacrifices himself by drawing the demon into himself and jumping to his death.

Merrin dies during the exorcism, and Karras demands that the demon enter him instead of Regan. He then throws himself from the window, sacrificing his life to free her. Chris and Regan eventually prepare to return to Los Angeles. The novel's epilogue also brings Dyer and Kinderman together in friendship, giving the aftermath a human connection beyond the deaths and the immediate defeat of the possessing force.
Original context
Why it matters
The horror is also about helpless love
Chris keeps searching because she cannot accept that her daughter is unreachable. The supernatural terror matters because it attacks that ordinary parental need to protect.
Sacrifice answers doubt without erasing it
The ending does not turn Karras into a simple believer. It shows that he can act with love and courage even when certainty is damaged.
Key turning points
Medicine failing changes the kind of story this is
As medical explanations collapse, the novel moves from diagnosis into spiritual crisis. The shift matters because it changes what kind of courage is required.
