A documentary about the life and works of José Mario Branco: musician, composer, poet and activist, among many other things. The shooting started in 2005 and for 7 years it moved between Portugal and France, filming rehearsals, album recordings, conversations and shows. This man of all trades speaks about music, his ideas, his generation, the Second Republic, the Portuguese Colonial War, his imprisonment and his exile. It's the portrayal of a man that has greatly influenced the artistic and cultural Portuguese panorama, and for whom "the song was [always] a weapon".
