Two brass bands, the Flemish 'St. Cecilia' and Walloon 'En Avant', are contenders for national pre-selection for the final of the European Union's Best Brass Band contest. The Walloons are blown into the final by Hugues, their exceptionally talented trumpet player; while Willy of the Flemish band hits the highest note after the band's final chord, but afterwards drops dead on stage. But Elke, daughter of St. Cecilia's conductor, has an idea about how to beat the competition.
