Documentary portrait of José Domínguez Muñoz, better known as "El Cabrero" (French for "the goatherd"), Spanish libertarian flamenco singer born in Aznalcóllar, province of Seville, in 1944 and filmed over two weeks in 1988 in Seville, Aznalcóllar, La Carbonería de Sevilla and Marinaleda, and in concert at a recital in Bayonne. Politically committed, El Cabrero defines himself as a libertarian. Since the 1970s, he has been close to the anarchist movement. For many years, he was a member of the anarcho-syndicalist Confédération Nationale du Travail.
