At the end of a long, dirt road, in a secluded Victorian House, lives Lila, an agoraphobic poet suffering from writer’s block. Lila’s hard-working husband, Samuel, who is vaguely aware of the demons that haunt his troubled wife and keep her pacing the floors in the dead of night, does his best to quietly support her, but is himself isolated by the consequences of past actions.
One morning, while Lila is trying desperately to write, she hears a noise on her front porch, and goes to investigate. On her usually desolate driveway, she meets a charming and strangely familiar fellow riding an old-fashioned bicycle. Barrington, as the man is called, captivates Lila more and more during his increasingly ghostly visits, and under his enigmatic spell she begins to deteriorate mentally and physically.

 Alarmed by Lila’s degeneration, Samuel returns to St. Agatha's, the cloistered convent / orphanage where Lila grew up; a dreary place that has, for the past ten years, been hiding secrets belonging to both of them. After a confrontational phone call, he has an uneasy meeting with the convent director, Mother Anne, who knows more than anyone what is contained in Lila’s painful history.

With Lila weakening, Barrington grows stronger, and his genial manner soon fades into petulant,
menacing obsession as he demands that Lila acknowledge who he is and resolves to make her
pay for what she has done to him, thrusting her into a terrifying fight for her life.
