In the near future, Japan is the victim of terrorist attacks on its nuclear power plants. Irradiated, the country is gradually evacuated to neighboring states. Tania, suffering from a long illness and originating from South Africa, awaits her evacuation order in a small house lost in the mountains. She is watched over by Leona, her first generation android offered to him by her father. Both become the last witnesses of a Japan which is slowly extinguished and empties itself in order of priority, sometimes according to discriminatory criteria. But gently, fear gives way to poetry and beauty.
