Following their victory in the Kansai regional competition qualifying round, the members of the Kitauji High School concert band set their sights on the next scheduled performance. Taking full use of their summer vacation, the band attends a camp where they are coached by their band adviser Noboru Taki and his pals who work as professional musicians. Kumiko Oumae and her pals are still motivated to win gold in the Kansai competition, but difficulty comes when a former member of the band expresses interest in rejoining, bringing up terrible memories for the second-year members. Kumiko also learns about her teacher's unexpected history and the driving force behind his ambition to lead the band to success. Hard work will be required to reach nationals.
