Armed with just one fixed camera and a few telling questions, Brazilian maestro Eduardo Coutinho gives us a lesson in film, and in passion. Seated in a chair on an empty stage, he asks his compatriots for a song that has profoundly influenced, determined or even irrevocably changed their lives. One by one, they tell us what this song is and then sing it themselves, a cappella, as if at an audition. The song in question is often accompanied by a poignant story or an unexpected confession. Exceptional people and beautiful songs, all of which talk about how love, lust and desire can determine, enrich, and sometimes derail our lives.
