Les lendemains de veille tells the story of Vincent, Malo, Lola, Matéo, Blaise and Xavier. At the time they were young and had a dream, that of living together; free and autonomous. And this dream had a name: "The community of the days before." However, their group ended up doing like everyone else and they gradually lost sight of each other. They hadn't made a date in the future, but the death of one of their own decided otherwise.

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.
