It is a fictional tale about a young woman's desperate search for her fiancé who might have been killed during World War I. It was based on a novel of the same name, written by Sebastien Japrisot, first published in 1991.
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.
