An elderly couple lives in a mountain village, working tirelessly in their fields. One evening, the husband sees a group of mice moving quickly and follows them to a sumo match. The couple discovers that the mice hold regular tournaments but often lose. Concerned, they prepare a meal of saury fish dumplings and grilled tofu with miso for the mice. They also create new red sumo outfits for the team. The mice then prepare for the next competition.
