At Chez Louise she serves the French militia men as well as normal customers and would willingly forget all about the war. But when going to see a supplier she comes across an injured British paratrooper and feels that she must help him.
With the help of her friend Emile she hides the injured soldier in her cellar. But the next day a German officer arrives purporting to be a sommelier and installs himself in her room, causing her to move into another room with Madeline who helps at the bar.
An early attempt to get the soldier to the Resistance is thwarted and there follows a cat and mouse situation as Louise humours the German officer while treating the British soldier for his injuries. This marks Louise as a German sympathiser in the eyes of some people.
Louise ultimately makes contact with a local notary who was to be the soldier's contact in France. The notary's daughter becomes the contact and plans are made to move the soldier. But the Germans are one step ahead, the German officer clearly being somewhat more than a sommelier.
The opening scene of this film tells us that the story doesn't end well, the remainder of the film showing us why. It's a sensitive story of a woman who isn't looking for trouble but because of her humanity finds herself involved in a situation that escalates out of control.
Louise is played by Line Renaud who is now 91 and would have been 80 when the film was made.
