Folk musician Simone returns to the house of her estranged mother, who is recently deceased. She refuses to attend the funeral or take any belongings, explaining that her mother subjected her to sinister ritualistic elements including seances as a child, before she was removed from the home. Shortly thereafter, she begins experiencing unexplained phenomena; she hears her mother's voice calling her name, starts suffering from disorienting dizzy spells and comes down with an excruciating pain in her back. She is referred to psychiatrist Dr. David Priestly, who believes her symptoms to be psychiatric in nature.
