In 2017, a high-school drama club in a disaster-hit area in Northern Japan chooses the 2011 earthquake and tsunami as the theme for a play to be performed at a national competition. Most of the students in the play didn't experience the tsunami firsthand and have avoided talking about it at school. But they take on the challenge of facing the disaster and learning about the sufferings of survivors. They hope their play will keep alive and spread the memories of what happened in their hometown.

Mao Higashi runs a grocery truck service in Mie Prefecture in central Japan, delivering fresh produce, ready-made meals, and some friendly chit-chat to elderly residents in her town. During her university days, she saw a TV program about how hard it can be for older people to buy groceries – an echo of her own grandmother's difficulties. Thinking there may be many others needing easier access to food, Higashi set up her grocery truck business. 5 years later and now 27, Higashi opens up a brick-and-mortar supermarket in order to boost her sales. But shortly after the opening, she receives very worrying news.
