In 1848, as Italy becomes engulfed in a bubbling revolution to finally get rid of the ruling Austrians, a patriotic prisoner named Cainazzo begins to wonder if he will soon get the chance to see the revolution in action away from his prison cell. Suddenly, a cannonball comes flying through the air and knocks the main wall of the prison down. Excited to have a chance to see the change taking place in person, Cainazzo hits a bumpy road when one of his former fellow prisoners yells out to all the revolutionary gangs that Cainazzo is not a patriot, but is in fact a traitor!
