The Exorcism (2024)

In New York City, Tom, an actor playing a priest in a supernatural horror film called The Georgetown Project (resembling The Exorcist), is inspecting the set alone when he is mysteriously killed by a supernatural force.

Peter, the film’s demanding director, taps aging, alcoholic actor Anthony Miller to replace Tom in the film. Anthony's daughter Lee, suspended from high school, is his personal assistant on the film. Both are recovering from her mother's death. Miller's background as a sexual abuse victim comes out, and he has difficulty on the film set and off, often having flashbacks to his molestation. Peter discusses replacing him, and derides Miller's troubled past and lost faith. Lee becomes increasingly concerned about her father's bizarre behavior, including cutting himself, sleepwalking, and refusing to take his medication.

Meanwhile, Lee makes friends with Blake, a popular TV actress who plays a possessed girl in the film. The two of them consult Father Conor, a Catholic priest and psychiatrist who is a consultant for the film, about Miller's frightening behavior. Miller acts on set as if possessed, contorting his body and slamming his head into a table. He is replaced by co-star Joe, who was originally playing his colleague. When alone on set, Joe sees a phantom of Miller and is killed by flying glass from a mirror. At home, Miller suddenly attacks Lee, then jumps out a window.

Father Conor decides to perform an exorcism. The possessed Miller, having survived the fall, is hiding on set. Lee finds Conor and Blake paralyzed in front of Miller, who ridicules Lee's attempts to use a prayer book. She manages to burn him with a crucifix, which snaps Conor and Blake out of paralysis. Conor offers himself to the demon, telling the girls to run. After Conor is possessed, Miller is roused to stab him with the crucifix, and to use the prayer book's exorcism rite sincerely as Lee and Blake also join in. Conor catches on fire and the demon is defeated.

Sometime later, Miller kneels in a confessional and declares "Forgive me, Father, for I have sinned. It has been one day since my last confession," signaling that he has returned to Catholicism. He shares that things have never been better between his daughter and him, muses on the meaning of forgiveness, and concludes what's happening at that point in his life "must be grace--it feels like grace." We see Lee on a beach in LA, emailing her latest film script to her father, with a note that she'll see him tomorrow.
