Valentin, a young man with a dark sense of humor, has lost everything: his girlfriend, his job and his apartment.  He squats with an absent uncle in a nice neighbourhood.  On the same landing lives Hélène and her son Jérémy.  Strong and independent, Hélène is a successful author who fights social inequalities and prejudices through her books. Between them, a cat who comes and goes, a son in search of a father, a sister in search of a lover, an stuck editor and their differences... Who knows, maybe one day all that will bring them closer?
