Sarah is forced to the edge of sanity by the ghosts of her family's past. Suffering from violent and bloody hallucinations, she seeks the help of psychiatrist and friend Michael Brink. After being sent to an institution in a catatonic state, covered in blood from stabbing her unfaithful boyfriend, Sarah is forced to confront the truth about her father's death and the demon, Jack, who caused her father's suicide and who is now the reason for her horrific hallucinations. Unlike her father, Sarah refuses to kill herself. She bargains for her life and succeeds. In Sarah's struggle to regain her life and her sanity, she discovers there is more to the world than she could ever have imagined, and it leaves her seeking the answer to the nagging question, "Who is really mad?"
