In the spring of 1970 a small village in Valais experienced unusual turbulence. Is it because of the federal vote on women's suffrage? Or in the upcoming foreign infiltration initiative? No, it's worse: the brass band is falling apart! Half of the village blames Aloys, the other half blames Pierre. What begins as a musical conflict soon leads to a political conflict and even extends to love.
