In November 1918, a few days before the Armistice, when Lieutenant Pradelle orders a senseless attack, he causes a useless disaster; but his outrageous act also binds the lives of two soldiers who have nothing more in common than the battlefield: Édouard saves Albert, although at a high cost.

In Belleau Wood, France, during the Great War, a soldier named John writes a letter home to his wife Sara in Milwaukee. He writes that her picture "helps me remember what it was like to be me." He tells her about sorties into No Man's Land, and that they have orders tonight to charge. Then, his letter becomes a report of that charge: toward an armed German soldier who doesn't fire, even when John reaches him and jumps into the trench beside him. What happens next brings silence and an end to the letter.
