Joshin, a nun at Taiseizan Mankoji Temple, a nunnery in a peaceful rural town, is undergoing a regular checkup from the local doctor, Kimura Kamekichi. After the checkup, Kamekichi makes a bold request. His wife has been hospitalized in a large hospital for over a year, and they have not had a sexual relationship for a long time. So he asks Joshin if he can comfort her just once. Knowing Kamekichi's earnest and clumsy personality, Joshin grants his request on the condition that he does not tell anyone.
