July 1911, Jean Jaurès is 51 years old. Invited by the Argentine socialists, the great orator travels to Latin America for the greatest journey of his life. He discovers a new continent, an America whose indigenous populations, from North to South, are being massacred, a land of violence, immigration, and conflict. During public lectures, he unfolds his ideas and captivates audiences attentive to his humanist discourse, informed by a vast historical culture.
