A building, its parking lot, its trash cans, its gardens and its inhabitants of a small suburban town of 30,000 inhabitants in the Paris region: Le Plessis-Robinson. Three families live here, in privacy, the torments of ecological awareness. This is their story of a year facing the injunction to act for the environment. Between enthusiasm and anxiety, between action and resignation, story of their hopes, their renunciations, their small arrangements, their conflicts, and their deep desire to live.
