In a bid to bring back life to their town after seeing its population dwindle in recent years, the manager of a shopping mall in northern Saitama Prefecture and the executive director of the Honjo Chamber of Commerce start a project to put together an improvised jazz band from local citizens. A former music teacher (Shimizu Shogo) is coerced into becoming the band leader, but the other prospective members are all elderly amateurs with little knowledge of music.
