After a whirlwind romance, a young woman returns to the opulent, secluded Long Island mansion of her new fiancé Max Winter, a wealthy politician and recent widower. The house is steeped in the memory of Max’s beautiful first wife Rebekah, who haunts the young woman’s imagination and feeds her uncertainties, while his very alive teenage daughter Dani makes her life a living hell. She soon realizes there is no clear place for her in this twisted little family. As the soon-to-be second Mrs. Winter grows more in love with Max, and more afraid of Dani, she is drawn deeper into the family’s dark secrets --- the kind of secrets that could kill her, too.
