Nézze meg a Teljes Film Magyarul. The Trombone family is very musically inclined, but their neighbours, the painter Pierre van Hall and his wife, are being driven crazy. This turns into a fight between the neighbours that gets way out of hand, because their reactions to each other become increasingly extreme; at one point a brass band is even used. The police ultimately force the quarrelling neighbours to make peace, by threatening them with jail.
