Since he was young, salesman Albert Dehousse (Mathieu Kassovitz) wanted to be a hero. Following the liberation of France after the Second World War, Albert leaves his home and wife and sets out for Paris where he befriends a young Captain, Jean Dionnet, and makes the acquaintance of Monsieur Jo (Jean-Louis Trintignant), a collaborator turned Resistance fighter. Albert, already a but of a fibber, begins his life anew with a fully fabricated identity of a daring Resistane hero, based on library research and the war yarns of Monsieur Jo. But his performance so captivates the French upper crust that he's soon way over his head - and holding a key embassadorual position. A gently comic take on the human need to reinvent oneself, with the lightest satirical touch.
