Overview: 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.
