Guarda su Altadefinizione. The Chicago Haymarket tragedy, where a bomb thrown into the ranks of Police was followed by an eruption of panic and violence resulting in a trial and execution of presumably innocent workers' rights activists, is examined in this feature documentary film. Expert historians and professors present the history of the bomb, the anarchist movement of the 19th century, and the labor struggle of working people fighting for a shorter work day during the industrial might of America's Gilded Age.
