When frightening and unexplainable events lead Dana to discover the long lost key to a room in the attic, she accidentally unlocks a host of horrors that reveal the house's past is terrifyingly tied with her own. A town historian tells Dana that houses of the well to do often had a "disappointments room" where children with special needs or deformed would be isolated so as not to embarrass the family. Dana uncovers the shocking story of a judge whose daughter was kept in such a room in her house and the spirit of the deformed girl and the monstrous judge still linger. She starts to see this demonic spirit who threatens her own child but by doing so she begins to doubt her own sanity.
