Orphan: First Kill (2022)

On January 26, 2007, Leena Klammer, a 30-year-old Estonian psychiatric patient with the appearance of a 10-year-old, escapes the Saarne Institute by seducing and killing a guard, then hiding in the car of art therapist Anna. After killing Anna in her home, Leena looks up missing American girls and finds that she looks like an age projection of Esther Albright, a girl from a rich family who went missing on May 2, 2003. Leena introduces herself as "Esther" to a Russian police officer and claims her parents are in the United States.

In Darien, Connecticut, artist Allen Albright and his wife Tricia are informed by Detective Donnan that their daughter has been found. Tricia travels to Moscow and brings "Esther" home. There, Leena becomes infatuated with Allen and tries to separate him from Tricia.

While Tricia and Allen are away, Donnan arrives at the house and acquires Leena's fingerprints. When Donnan finds that the fingerprints do not match Esther's, Leena, who has been tailing him, stabs him with a knife. Tricia arrives, having followed Leena, and shoots Donnan dead. Tricia reveals that the real Esther died in 2003 during an altercation with her older brother Gunnar, which Tricia covered up. Tricia only let Leena pose as Esther to placate Allen. Leena and Tricia dispose of Donnan's body in a cellar hatch which contains the real Esther's body. They frame his disappearance as a vacation trip by forging an email to the police station.

When Leena proves too difficult to control, Tricia and Gunnar (who isn't remorseful) plot to kill her. After two unsuccessful murder attempts from both sides, Leena tries to flee by stealing Tricia's car, but she is soon found by a police officer.

After Leena is brought back to the Albright house, Tricia and Gunnar try to kill her, but Leena fights back and flees. She ambushes Gunnar in the art room with a crossbow and stabs him to death with his fencing sword. Tricia and Leena fight in the kitchen, fleeing to the roof after inadvertently setting the house on fire.

As Allen returns home, he finds Tricia and Leena clinging to the roof, calling for him. While Leena is claiming that Tricia attacked her, Tricia tries to reveal the truth about Leena. Allen helps Leena first, causing Tricia to fall to her death. When Allen checks Leena's face, her fake teeth start to fall out, revealing she is not Esther. Leena tries to justify herself and confesses her love for him, only for a shocked and disgusted Allen to call her a monster. An enraged Leena accidentally pushes him off the roof.

Leena cleans herself up and dresses up again as Esther. Later, "Esther" is moved to an orphanage and waits for a new family to adopt her.
