30-year-old factory worker Simon lives a solitary existence on a decrepit farm in the remote French countryside. Devoting his time to caring for his sister Estelle, who was left severely disabled when a childhood game went horribly wrong, Simon is plagued by guilt and depression. But he sees a way out, looking to otherworldly forces as a means of liberating both himself and his sister from the corporeal prisons in which they are confined.
In 2026, a radical change requires everyone to live naked in a pacified and peaceful France. But the murder of a young woman found dressed revives tensions. The investigation is entrusted to a young inspector who collaborates with her ex-partner, just out of the coma in which he had fallen at the time ... where everyone was still wearing clothes.
