In this tense tale of psychological terror, Vivian Miller (Young) is a young twenties woman who’s serving out her jail sentence at a work release program in the Midwest. Her 90 days of probation takes her to The Cawdor Theater, a dilapidated summer stock theater run by Lawrence O’Neil (Elwes). Lawrence, a failed Broadway director, is now reduced to staging amateur productions with young parolees and raging over the mistakes from his past. Vivian’s arrival in Cawdor starts a terrifying series of events that brings Lawrence’s secret past to the present.  After Vivian views an old taped stage production of Macbeth, a force of evil is unleashed which soon turns its sights on her. With the help of Roddy (Welch), a local outcast, Vivian sets about trying to discover who the supernatural killer on the tape is before she becomes the next victim.
