Five French soldiers are convicted of self-mutilation in order to escape military service during World War I. They are condemned to face near certain death in the no man's land between the French and German trench lines. It appears that all of them were killed in a subsequent battle, but Mathilde, the fiancée of one of the soldiers, refuses to give up hope and begins to uncover clues as to what actually took place on the battlefield. She is all the while driven by the constant reminder of what her fiancé had carved into one of the bells of the church near their home, MMM for Manech Aime Mathilde (Manech Loves Mathilde; a pun on the French word aime, which is pronounced like the letter "M". In the English-language version, this is changed to "Manech's Marrying Mathilde").
