At the end of his life, gravely ill, François Truffaut took refuge with his ex-wife Madeleine Morgenstern. She tried to keep him occupied during his long agony. The filmmaker confided in his friend Claude de Givray, with the intention of writing his autobiography. Too weakened, he abandoned the project. The film reveals part of this final story.
