Simón, el hijo del pueblo.

The story of the mythical anarchist begins to weave on May 1, 1909, when the police repress a massive anarchist march in Buenos Aires, leaving dead and wounded. A few months later, the carriage of Ramón Falcón, the police chief who commanded the repression, explodes and flies through the air. For the attack, a young Ukrainian is arrested: Simón Radowitzky.
