1857. The young aristocrat Carlo Pizacane, Duke of San Giovanni, with 20 like-minded people, seizes the prison on the island of Ponza and frees more than 300 prisoners. They must form the nucleus of a new liberation army against the Bourbon-ruled Kingdom of Naples. But there is no general uprising. With a small detachment, the young revolutionary finds himself locked in the walls of the town he captured without hope of help.
