The Winters family seemed to have it all: a grand home, a trio of radiant daughters, and a sense that they were safe in their affluent corner of America. But when five-year-old Ellie disappears, the fault lines within the Winters family are exposed. Fifteen years later, Caroline, now a New Orleans cocktail waitress, sees a photograph of a woman in People Magazine. Convinced that it is Ellie all grown up, Caroline embarks on a search for her missing sister.
