After dedicated service in the Great War, a Jewish barber spends years in an army hospital recovering from his wounds, unaware of the simultaneous rise of fascist dictator Adenoid Hynkel (also Chaplin) and his anti-Semitic policies. When the barber, who bears a remarkable resemblance to Hynkel, returns to his quiet neighborhood, he is stunned by the brutal changes and recklessly joins a beautiful girl and her neighbors in rebelling.
