Mary, who lives in a certain town, is worried about balancing accounting work, cleaning duty, and family life. One day, as her dissatisfaction with the town grows day by day, she is asked by the president, Nakata, to participate in the Mama's Volleyball Tournament. Reluctantly, Mary can't refuse and heads to practice, which is held every Saturday, but for some reason, only a few of her middle-aged men are there. Her middle-aged men quickly change the clothes of Mary, who is confused, and while glaring into her eyes, they sexually harass Mary's voluptuous woman.
