The film appears to start in August 1942 in Vichy France. However, the Gestapo are shown as hunting the main character, there are German troops in the factory where his daughter works and there are German tanks (quite convincing Panzer IVs) in the streets. Unfortunately, the Germans did not occupy the Free Zone until November 1942 (for example, Klaus Barbie, the actual head of the Lyon Gestapo, arrived in Lyon in November 1942).
