The Necklace tells the stories of three women, each with a dangerous secret. There is 80-year-old mafia widow Kate Brady, determined that her secret will die with her - beautiful, blond and famous Andrea Pryor is being blackmailed for her secret - and 18-year-old Marianne Woodsman whose secret is hidden in her family's Park Avenue penthouse. Marianne runs for her life from her dangerously dysfunctional family, through a homeless shelter and a brothel until her story intertwines with Kate's and Andrea's in a three-generational embrace.
