In the Catholic girls‘ school choir, Celia‘s voice must not be heard. But her mute acceptance of the conservative dictates is soon shaken up by the arrival of a new classmate, Brisa. Standing on the threshold of adolescence, Celia discovers a new thirst for life in all its multifaceted glory. A bond quickly develops between the two girls, and together they rail against the authority figures and their rigid rules. In small acts of rebellion, Celia finds the courage to express her growing distrust of the value system governing her world in 1990s Spain, as questions start to arise about her own family background.
