To overcome the grief of losing her twin brother, the director-husband of a talented but naïve and head-strong young actress persuades her to appear in a one-person show he has written for her, at an old, disused theatre in a small East-coast town.
The show bombs on the first night, after she fails to take heed of the advice offered by an unseen, enigmatic member of her audience. As she opts to stick with the direction of her writer-director husband, she puts her sanity and their lives in jeopardy. After her husband suffers a tragic accident, she has only two nights to turn her show into an overnight sensation and avoid further tragedy.
As the, now imprisoned, actress recalls her story to a visiting psychologist, the dark and far-reaching consequences of her final night's performance are revealed.
