In 1936, the Nazi are little more than loud, brutish bores to fifteen-year old Stephan Neuman, the son of a wealthy and influential Jewish family and budding playwright whose playground extends from Vienna's streets to its intricate underground tunnels. Stephan's best friend and companion is the brilliant Žofie-Helene, a Christian girl whose mother edits a progressive, anti-Nazi newspaper. But the two adolescents' carefree innocence is shattered when the Nazis' take control. ; ; There is hope in the darkness, though. Truus Wijsmuller, a member of the Dutch resistance, risks her life smuggling Jewish children out of Nazi Germany to the nations that will take them. It is a mission that becomes even more dangerous after the Anschluss-Hitler's annexation of Austria-as, across Europe, countries close their borders to the growing number of refugees desperate to escape. ; ; Tante Truus, as she is known, is determined to save as many children as she can. After Britain passes a measure to take in at-risk child refugees from the German Reich, she dares to approach Adolf Eichmann, the man who would later help devise the "Final Solution to the Jewish Question," in a race against time to bring children like Stephan, his young brother Walter, and Žofie-Helene on a perilous journey to an uncertain future abroad.
