In the spring of 1959, The Diary of Anne Frank has just come to the silver screen to great acclaim, and a young woman named Margie Franklin is working in Philadelphia as a secretary at a Jewish law firm. On the surface she lives a quiet life, but Margie has a secret: a past and a religion she has denied, and a family and a country she left behind. She is really Margot Frank, older sister of Anne, who did not die in Bergen-Belsen as reported, but who instead escaped to America. But now, as her sister becomes a global icon, Margie's carefully constructed life begins to fall apart.
