A band of young musicians will do the impossible to boycott a song they didn't like at all, and that's supposed to represent Spain in a famous musical contest. An unusual film by the odd Zulueta in which, after the success of Spanish singer Massiel in Eurovision contest, this kind of contests are parodied with an insane story shot without a script and with the performance of several top music bands of that time.

Un grupo de jóvenes músicos hará lo imposible para boicotear una canción que no les gusta nada, y que va a representar a España en un famoso festival de música. Una insólita cinta del singular Zulueta en la que, tras el éxito de Massiel en el Festival de Eurovisión, se parodia este tipo de concursos con una delirante historia rodada sin guión y con la actuación de varios grupos punteros de la época.
