Octavio Alberola has spent eighty years thinking, living and evolving his life from the perspective of anarchism and he has never hesitated to question each one of his actions to the point of dramatically effecting his very existence. He belongs to the generation that lived through the events of the twentieth century directly, as a participant: war, dictatorship, exile, the precariousness of secrecy, the internal battles within the anarchist movement of the post-war period and the huge social struggles across the world. Agustín Comotto captures the essence of Octavio's thoughts, the values, the contradictions, the fears and the hopes. Together they take a journey through the twentieth century anarchist experience to be at the heart of those essential events in which Octavio was both witness and actor.
