In a typical Japanese village, Yoichi Ono lives with his wife, Izumi and his parents. The Ono family lives a frugal but happy life as dairy farmers in the peaceful village. One day, the worst earthquake in history strikes, causing a nearby nuclear power station to explode. Their neighbours, who live within the range of the nuclear power station, are forcibly ordered by the government to evacuate. But the Ono family, whose property sits half in and half out of the designated range, must decide whether or not to leave their home.
