Tomorrow We Live.

A young French idealist arrives in "St Pierre-le-Port", a small town near Saint-Nazaire, a major port and base of operations for the German Navy, particularly their U-boats. The first half of the film often has a lighthearted tone; the Germans are portrayed as bumbling and easily outwitted. After the Resistance successfully sabotages a German armaments train, the SS take charge of the town, and the occupation takes a brutal turn.
