Sawyer Valentini (Foy) goes to visit a counselor over her fears regarding a man named David Strine (Leonard) who stalked her for two years. She then finds herself involuntarily committed to a mental institution, Highland Creek, where David works as an orderly under another identity. Although Sawyer tries to tell others who he really is, nobody will listen to her.

- Mama Bear: Angela, who confronts the administrator and head doctor at the facility, vowing to do everything in her power to get Sawyer out.
- Neck Snap: Happens to Violet, courtesy of David.
- Ooh, Me Accent's Slipping: Claire Foy's English accent slips through numerous times during the film, especially when incensed, making e.g. "the counselor said the forms were routine" sound more like Elizabeth.
