In an eerie and atmospheric setting, Janet, a young woman tormented by traumatic dreams, struggles to distinguish reality from hallucination. Haunted by memories of her mother, whom she saw sent to an asylum after a violent episode, Janet attends a private boarding school where she is plagued by nightmares of a veiled woman attempting to harm her. Her guardians, hoping to stabilize her mental state, suggest she return home for respite. Upon arrival at the sprawling family estate, her condition seems to worsen as the nightmare-inducing visions intensify.

The mansion's labyrinthine halls, filled with shadows and secrets, do little to calm Janet's troubled mind. She confides in Grace, the new nurse employed to watch over her, but Janet's fears grow as the haunting figures from her dreams begin to appear within the decaying walls of her home. Her guardian, Henry Baxter, a lawyer with his own clandestine motives, attempts to reassure her, though Janet’s disintegrating sanity poses a threat to both herself and those around her. As the past unfurls its grip upon Janet, the distinction between imagination and reality blurs, leading her into a web of family secrets and dread that seem insurmountable. In this suspenseful narrative of psychological horror, trust is as tenuous as Janet’s grip on reality, setting the stage for unexpected revelations and chilling developments.
