1959. 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 life she once lived, a past and a religion she has denied, and a family and a country she left behind. Margie is really Margot Frank, older sister of Anne, who did not die in Bergen-Belsen as reported, but who instead escaped the Nazis for America. But now, as her sister becomes a global icon, Margie's carefully constructed American life begins to fall apart.
