A half-dozen percussionists engage in an anarchistic wave of guerrilla performances that terrify the populace of a Swedish metropolis, and a tone-deaf cop─the black sheep of a family of successful composers─finds a personal impetus for bringing them to heel. Engaging blend of political satire and musical celebration stars Bengt Nilsson, Sanna Persson, Magnus Börjeson. 102 min.
