Sachie, from Japan, opens the "Kamome Diner" in Helsinki, Finland. The specialty menu is Onigiri rice ball or o-musubi. However, the only customer day after day is a geeky Japan enthusiast, Tommi, a Finnish boy obsessed with the Gatchaman cartoon. One day, two Japanese ladies, each with some personal issues, come to help at Sachie's diner. The number of customers gradually increases, but the diner seems to attract only those with problems. Conversation with Sachie and the tasty food seem to resolve people's woes.
