40 years of working at the expense of family time. A "hot spring trip" planned by her daughter, Fuyumi's husband, Taro, in order to thank Akio, who has finally reached retirement age, and Eiko, who has continued to support her husband. Excited by the family trip that Akio never got to go on when he was active, the party came to a certain hot spring town with feelings of gratitude towards Taro. After arriving at the inn, Eiko soaks in the hot springs with Fuyumi. However, a man peers into Eiko's body with suspicious eyes. What is that man...!? ?
