Actress-director Zabou Breitman embarks on an unusual adventure: imagining the life of a boy discovered in an old photo from an album bought at a flea market. These are the images and memories of an unknown family, which somehow feel familiar. At the center is the boy, with his gaze that is both gentle and melancholic yet joyful. Who is he? What is his true story, the one that unfolds between the lines? What if every individual were also the unwitting hero of a tale? This dizzying family investigation blurs the lines between reality and fiction, sometimes merging them completely.

Doctor Petypon, a respectable doctor, partied until early morning at Maxim's. His best friend discovers him asleep at noon under an overturned sofa. From the bedroom comes the Môme Crevette, a dancer from the Moulin Rouge. She is forced to pretend to be his wife. It stings at the game and causes a cascade of misunderstandings, imbroglios and drama at a frantic pace.
