Mikako (Haruka Ayase) is a young high school teacher who has just graduated from another school. Excited to have a new job, she offers to coach the boys' volleyball team. She finds out that the team consists of no more than 5 guys, all of whom are losers who have never touched a volleyball and only think about girls. To encourage them, she agrees with them that if they do their best she will show them her breasts. From that moment on, the boys do everything they can to win a match. Although she feels uncomfortable, she is still proud of her team, and begins to bond.
