This biography begins its story with a young Pancho, driven to repulsion of the Diaz regime when he witnesses one of its soldiers kill his father. Pancho turns against the government, becoming one of the most ruthless bandits ever known to Mexico, but eventually helping to put the honorable Francisco Madero to power. After Madero's assassination, Pancho himself is called upon to lead the masses, but being a better fighter than a bureaucrat, he relinquishes the presidency when he is able to restore Mexico to its people.
