The movie is based on the novel by Tatia de Rosnay. In Paris, July 1942 Sarah, a ten-year-old girl, is taken with her parents by the French police as they go door to door arresting Jewish families in the middle of the night. Desperate to protect her younger brother, Sarah locks him in a bedroom cupboard—their secret hiding place—and promises to come back for him as soon as they are released.
Sixty Years Later: Sarah’s story intertwines with that of Julia Jarmond, an American journalist investigating the roundup. In her research, Julia stumbles onto a trail of secrets that link her to Sarah, and to questions about her own future.
