“La Canción” tells the story, in a fiction series which takes in the main events: the enrolment of real life Artur Caps, an Austrian emigré but king of TVE’s variety shows, to choose the song; the choice of Joan Manuel Serrat, an icon of Catalan dissidence so symbol of Spanish modernity, to sing it; when Serrat pulls out, denied the right to sing “La, la, la” in Catalan, the desperate recourse to firebrand Massiel, who, despite little time to rehearse, pulls of a great performance at London’s Albert Hall. Caps’ wingman is the series’ protagonist Esteban, pig ignorant about music but driven by the initial dogged ambition of scaling posts in Franco’s government.

It follows a mother who is involved in the homosexual movement of the seventies.
