Swing Girls is a feel-good comedy following Yaguchi’sfamiliar formula of novices starting a new and slightly unusualactivity, suffering various problems and set-backs on the way, butfinally triumphing in the final reel.
The films starts with a group of girls having to spend their summervacation in catch-up mathematics lessons with a boring teacher. One daythey are given the chance to escape the lessons by delivering lunchboxes to members of the school's brass bandclub. When the band members become ill, the girls realise that they canpermanently skip mathematics lessons if they take the place of the sickband members.
The film then follows the various problems and situations theyencounter, from exercise regimes, learning to play their instruments,raising money, finding a teacher and entering a local musiccompetition. What started as an excuse to miss lessons becomes apassion, and they finally win glory in the concert hall.
