Sawyer Valentini, a young woman who has relocated to a new city to escape her traumatic past and her stalker, struggles to adjust to her surroundings and make connections in her new environment. Grappling with the lingering anxiety and perception of threat that her stalker, David Strine, has instilled in her, Sawyer seeks help from a therapist to cope with her distress. During what she believes is simply a routine consultation at a mental health facility, she inadvertently signs a form that commits her to a 24-hour stay at the institution.

Once admitted, Sawyer finds herself trapped in a nightmarish situation when her brief commitment is extended, and her protests are dismissed as delusions. Her sense of reality begins to unravel as she meets a patient who supports her suspicions that the institution is not what it seems and might be preying on vulnerable patients for insurance money. As she tries to advocate for herself amidst the indifference and bureaucracy of the facility's staff, her encounters with another patient named George Shaw deepen her conviction that her stalker has found her once again, leaving her in a fight for her sanity and safety within the very walls that are supposed to offer protection.
