At a university track team dormitory, Koyuki, the widow of the late coach, oversees dorm operations. Once a legendary track and field athlete herself, she provides strict guidance to the team members, supporting them at times with kindness, and at other times in erotic ways. She tells the athletes, "Don't worry—I'll protect this track team you cherished and nurtured." Her intense attitude, always demanding they show their true manhood, ignites a fiery passion throughout the entire dorm.
