In a small mountain village in Vichy France, a young Jewish woman who was forced to flee Paris finds a way to survive the Holocaust: forging identity documents for children being smuggled out to Switzerland by the Resistance.  She secretly preserves their records in a hidden book, alongside the vital messages she encodes in it, but when the Nazis destroy the library, she fears it is lost forever. One day though, decades later, a newspaper appears on her desk with a story about a newly discovered book that looks very much like her own. Can she now help reunite those lost during the war?
