Sarah's Key

In 1942, 10-year-old Sarah Starzynski (Mélusine Mayance) hides her younger brother from French police by locking him in a secret closet and telling him to stay there until she returns. She takes the key with her when she and her parents are transported to the Vélodrome d'Hiver, where they are held in inhuman conditions by the Paris Police and French Secret Service.

The deportees are transferred to the French-run Beaune-la-Rolande internment camp. The adults are deported to the Auschwitz concentration camp, leaving the children in the camp. When Sarah tries to escape with her friend Rachel, a sympathetic Paris police guard spots them. When Sarah begs him to let them go so she can save her brother, he hesitates then lifts the barbed wire to let them out.
