Kamagasaki is an "invisible" slum of Osaka that attracts day laborers and prostitutes since WW2. When the local gang has its treasured cauldron stolen, a war to find it begins involving the thugs, a 12 years old kid, a prostitute and a pickpocket, including the giant cauldron used to feed the destitute: The symbol of Kamagasaki.

Katsuo is a young boy dreaming to be a professional musician. However, when he's about to make his debut, he suddenly decides to go back to his hometown to see his old band. Finding other band members, they start practicing for a summer festival, but Katsuo's unreasonable behaviors upset his band-mates. The film's title reflects both Katsuo being a man of great talent ("ponchi"), as well as the clear blue skies ('Aozora") that make up the film's beautiful summer setting.
