David (Aidan Quinn) is a professor of spiritualism at Yale Jesus College. One day, he received an invitation from the three siblings of the Edbrook family to go to the mansion to investigate the supernatural events that occurred there. Robert (Anthony Andrews) is cold and alienated, while Simon (Alex Lowe) is just the opposite. He is a passionate and lively young man. What David cares about most is the youngest sister Christina (Kate Beckinsale). Her confidence and independence deeply attracted David. As time goes by, David can't resist Christina's charm and comes together with her. At the same time, the supernatural events that happen one after another in the house challenge David's faith again and again. One day, David actually saw the soul of his dead sister Juliette (Victoria Shalet). Under Juliette's guidance, David walked into a secret hidden for many years.
