Claire wakes one day to find herself chained in a basement. Her horror is magnified when she uncovers that her captor is her own mom! Helen assures Claire that the scenario is required and also "for her very own good." And to add to Claire's fear, in the days and nights to follow she is beset by odd phantoms as well as frightening experiences, finding herself precariously stabilized on a razor's side between reality and insanity, and ultimately required to deal with a dark truth.
