As a child, shy and troubled Luke witnesses the aftermath of a mass shooting at a neighborhood coffee shop. He meets another boy among the onlookers at the scene: cool and confident Daniel, who invites him to play and quickly becomes his friend. Although adults such as Luke's mother, Claire (Mary Stuart Masterson), cannot see Daniel, he appears physically real to Luke. The boys become close playmates, and their connection helps Luke cope with his parents' divorce. Their friendship comes to an abrupt end when Daniel convinces Luke that blending an entire bottle of Claire's psychiatric medication into a smoothie will give her superpowers. Instead, it results in a near-fatal poisoning. Claire convinces Luke to send Daniel away by symbolically locking him in her mother's old dollhouse.
Years later, the college-aged Luke (Miles Robbins) is paralyzed by anxiety over his future, his social life and his responsibility to his mother, who struggles with paranoid delusions and a hatred of her own reflection. He confides to his therapist, Dr. Cornelius Braun (Chukwudi Iwuji), that he is afraid he will eventually become just like her. One night, while sleeping over at his childhood home, Luke unlocks the dollhouse. Daniel (Patrick Schwarzenegger) reappears as an adult. His influence initially appears benign as he helps Luke thwart Claire's suicide attempt, succeed in school, and begin a romance with an artist named Cassie (Sasha Lane). However, he quickly starts exhibiting aggressive behavior, becoming enraged when Luke doesn't obey him. When Luke won't have sex with a psychology student named Sophie (Hannah Marks) on a date, Daniel forcibly takes over his body, has rough sex with Sophie and attacks Luke's roommate. Luke is banned from campus as a result and begins to question his own sanity, believing he may have schizophrenia. He attempts to banish Daniel back to the dollhouse but is unsuccessful.
