A rousing examination of free radio culture in Europe: "Were free radio stations created because the mass media could no longer make love?" the narrator asks. "Or because they did so reluctantly?" The Dardennes highlight the passion and loose network of individuals (engineers, broadcasters, listeners) who comprise this form of alternative media, giving emphasis to physical equipment like hidden transmitters. A family of listeners commends a station that broadcasts in the Alsatian dialect for preserving a minority language, and the documentary highlights free radio’s multilingual existence.
