As the twentieth anniversary of their agreement approaches, Lorna demands the fulfillment of Patrick's promise in exchange for his wealth, threatening dire consequences if he fails to comply. Disturbed by unsettling visions and the fear of losing everything he holds dear, including his idyllic family life with his wife, Marianne, and their beautiful daughter, Linda, Patrick seeks a way to escape Lorna's sinister clutches.

With time running out and Lorna's influence growing stronger, Patrick must confront the spectral past that threatens to destroy his present and future. Tension escalates as everything Patrick loves hangs in the balance, leading to a desperate struggle against both the supernatural forces at play and his own past decisions.
