When a high school brass band (for the school's baseball team), gets food poisoning, the only healthy member of the band (he wasn't able to eat the spoiled food that day) decides to call some indolent girls from the school (who inadvertently caused the food poisoning) to replace the band. Initially, of course, they are a disaster. But just when they start to get better, the original band returns. What's to do, then? What about forming a jazz-style band? Following the structure of his previous film, Water Boys (inept students finally prevail against all odds), Yaguchi made probably his best film so far. It's hilarious, full of great gags. All the actors are good, but the geeky girl named Sekiguchi steal the movie in my opinion.
