Set in the time of Napoleon wars, shows how the wars swept over the unfortunate Polish country at the beginning of the XIX-th century. Story revolves around the Polish legion under command of General Dabrowski, who then fought on Napoleon's side with the hopes of Poland's revival.

In the countryside near Normandy's beaches lives Marie, unhappy. It's 1945, she's married to Jérôme, a somewhat fussy milquetoast, diffident to the war around him and unwilling to move his wife to Paris, where she longs to live, shop, and party. A German outfit is bivouacked at Jérôme and Marie's crumbling château because its commanding officer is pursuing Marie. She's also eyed by a French spy working with the Allies as they plan D-Day. He woos her (posing to the Germans as her brother) and, in his passion, forgets his mission. Heroics come from an unexpected direction, and Marie makes her choice.
