When she was assaulted by her doctor, Claire Bartel reported him to the police, and rather than go to prison for his crime, he killed himself. The shock of the accusations and suicide caused the doctor's pregnant wife, Peyton, to have a miscarriage. Driven mad with rage, Peyton poses as a nanny for the Bartel family. Her plan: to tear Claire's life apart, seduce her husband and eventually murder the woman she blames for ruining her life.
