Michel Berthier, a senior executive at a mattress manufacturing company, has just been fired. As he does not dare to tell the truth to Juliette, his partner, he goes into debt to maintain the family’s standard of living, showering them with gifts. But soon he can no longer lie, and he decides to leave the house. After losing his money, his car, and his shoes, he meets Toubib, Mimosa, and Crayon, three “homeless” people who wash themselves in the restrooms at the Gare de l’Est. They take him under their wing and lead him to break into his former company in order to get sleeping bags and beds.
