Steve forces Peter to take Charlie to a high school party. Charlie, allergic to nuts, accidentally eats a chocolate cake containing walnuts. Having a severe allergic reaction, Peter rushes her to the hospital. On the way, Charlie sticks her head out the car window for air. Peter swerves to avoid a dead deer in the road. Charlie’s head is instantly decapitated by a telephone pole.

In a rage, Annie tells Peter she tried to abort him to prevent this. Terrified, Peter flees to the attic. Meanwhile, Steve is suddenly burned alive (the book’s fire ignites him). Annie levitates, saws off her own head (in a ghostly vision), and chases Peter. He jumps out the attic window, falling to the ground. He wakes up, not dead, but possessed—Paimon has entered his broken body. hereditary-2018-

Things escalate: Annie sees a ghostly figure of her mother. Steve finds Joan’s séance book in the trash, and Annie realizes Joan is a plant. That night, Steve burns the book, but it teleports back. Annie frantically searches her mother’s belongings and finds a photo album showing her mother with a demonic cult. The book, The Invocation of Paimon , reveals the plan: Ellen was the queen of a cult that worships King Paimon, a demon of knowledge. The goal is to place Paimon’s spirit into a male host—Peter.

Peter (now Paimon) descends into the treehouse behind the house. Inside, the decapitated, rotting bodies of Annie (now headless) and Charlie (whose head is now on a mannequin) bow to him. The cult members (including Joan) bow and whisper, “Hail Paimon.” Peter/Paimon lets out a victorious, demonic scream—and then makes Charlie’s signature clicking sound. The demon has finally been placed in a male host, fulfilling the hereditary curse that was always the plan from the moment Charlie was born. On the way, Charlie sticks her head out

Annie tries to protect Peter by burning Charlie’s sketchbook. As the book burns, she sees a photograph of herself as a child with her mother, and realizes her mother made her feed Charlie (from infancy) nut oil to induce the allergic reaction. Charlie was never a normal child; she was the temporary vessel for Paimon.

The family is shattered. Annie is consumed by guilt and rage. Peter is catatonic with trauma. Annie discovers a cryptic note from her mother: “Our sacrifice will pale next to the rewards.” Desperate to speak to Charlie, Annie attends Joan’s séance. Joan leads her in a ritual to contact Charlie’s spirit. The planchette moves on its own, and Annie feels Charlie is in the room.

The horror is not just supernatural—it’s about family trauma, mental illness, and the terrifying idea that your identity and suffering were never your own, but pre-scripted by your ancestors as a sacrifice to a demon.
