For the two 13-year-old blood-brothers Alex and Ferry, Hitlers war is an exciting game – which is not surprising since they live in a backwater town ignored by the Allied bombers. The only thing thats more interesting than watching enemy planes fly past is the burning desire to discover the secrets of sexuality with the fiery Rosa. But then bombs actually do start falling on their little town – and the boys are sent to a Czech spa to wait out the end of the war. Blessed with a beautiful singing voice, Alex joins the boys choir, insisting that Ferry join it too – blood-brothers share everything! But trouble is afoot when Alex replaces the “Hitler Youth” watchdog as lead soloist.
