Paris: 1942 Three lives intertwined in Nazi-occupied Paris: Paul, a brooding banker whose family was killed by the Gestapo, Rachel, a teenage Jew who leads her family's escape from the Germans, Claire, a demure bookstore owner who finds courage and conviction - all confronted by an infamous Nazi collaborator. In the sprawling network of catacombs underneath the Left Bank of Paris, they hide thousands of Jewish refugees, giving them new identities and leading them to safety. Together they move forward, outsmarting a ruthless enemy, overcoming obstacles, defying danger, moving farther and faster, almost invincible-until an innocent bystander notices something amiss and their entire world collapses around them.
