Set in 1979, follows 23-year-old teacher Mikako who was recently transferred to a junior high school school in Kitakyushu. Enthusiastic about her new job, she immediately volunteers to coach the boys volleyball team. Unfortunately, she finds the team only has 5 members--all of them geeks who spend most of their time obsessing over girls and no time practicing. In an effort to motivate the team, she gets coaxed into promising to flash them her breasts if they win the big tournament. The promise works like a charm and the kids immediately become fiercely determined to become better volleyball players. Mikako is nervous about the implications of her promise but pleased with the complete change in attitude of the team. Unfortunately the school finds out about it right before the first game, possibly jeopardizing her job.
