Оркестр старшей школы Китауджи занял первое место на конкурсе в Киото. Теперь принято решение, что Китауджи будет представлять Киото на конкурсе в Кансае. И вполне заслуженно: уровень игры у ребят значительно вырос благодаря отличному учителю и дирижеру — Нобору Таки. С этих пор репетиции будут жестче, ведь Китауджи нацелен на национальные соревнования.

Тем временем в рядах молодого оркестра происходят внутренние разногласия, которые помогают узнать друг друга лучше и укрепить дружбу между участниками.

Following their success in the qualifying round for the Kansai regional competition, the members of the Kitauji High School concert band set their sights on the next upcoming performance. Utilizing their summer break to the utmost, the band participates in a camp where they are instructed by their band advisor Noboru Taki and his friends who make their living as professional musicians.

Kumiko Oumae and her friends remain determined to attain gold at the Kansai competition, but trouble arises when a student who once quit the band shows interest in rejoining and sparks unpleasant memories for the second-year members. Kumiko also learns about her teacher's surprising past and the motivation behind his desire to lead the band to victory. Reaching nationals will require hard work, and the adamant conviction in each student's commitment to the band will be put to the test.
