A young man wanders and makes calls to elders who live alone. Saying “Granny, it’s me,” he lies to them that he is their grandson. An old lady, who runs a music shop in the declining shopping area in Amakusa, answers his call and warmly accepts him. Pretending as her grandson, he settles down in the town. He gets used to his friendship with young villagers, the sound and landscape of Amakusa, and the old lady’s everyday life.
Naraho town in Fukushima Prefecture is on the front-line of the government-funded nuclear power plant decommissioning work. Kokuhei Kusunoki is transferred from Aizu Wakamatsu City to Naraho Town to take over the Disaster PR Division. Murai takes Kokuhei around Fukushima including areas washed away by the tsunami. They examine the still incomplete railway lines, the unfinished decontamination area and villages in the danger zone, where deadly cesium continues to pile up. One day Kokuhei is told to organize a party to celebrate the professor who has been appointed as deputy director of the Atomic Energy Research Institute.
