When Emma's cancer takes a turn for the worse, she presents her new wife Josie a deathbed order: find someone new while Emma is still around to approve of her choice.

Claire wakes one day to find herself chained in a basement. Her horror is amplified when she discovers that her captor is her own mother! Helen assures Claire that the situation is necessary and “for her own good.” And to add to Claire’s terror, in the days and nights to follow she is beset by strange apparitions and frightening experiences, finding herself precariously balanced on a razor’s edge between reality and insanity, and ultimately forced to face a dark truth.
