After breaking up with her live-in boyfriend, Keiko quits her job in Tokyo and makes up her mind to move to Hokkaido. There, she finds a job at a post office in a small village of 800 people. Now in her mid-30s, she still has vivid memories of living in Hokkaido during junior high school-encountering deer on a mountain road or seeing baby foxes playing in the grassand had been longing to return. One day, while delivering mail, she meets a middle-aged man, apparently single. She takes a liking to him, and they grow closer. He works as the caretaker for 'Francis'-a hydroelectric mill powered by a Francis turbine, on the riverbank behind his house, that supplies electricity to the village. Soon, however, her idyllic days of romance in these peaceful surroundings are thrown into confusion by the specters of multiple women in his past. With a keen understanding of the human heart and an appreciation of the power of our environment, Masashi Matsuie immerses us in one woman's journey-through crises both internal and external-to a fresh understanding of life.
