Charlie works in a huge factory. The director orders to go faster. Unable to do it, Charlie is eaten by a machine and gets completely mad. So he begins to dance everywhere, to screw all that makes him think of bolts, like gentlemen’s noses, buttons on the dress of a secretary, until they decide to evacuate him. Released from hospital, Charlie is unemployed. After a misunderstanding during a riot by striking workers, the police take Charlie for the leader and get him to jail. At the refectory of the prison, Charlie absorbs, not by purpose some drugs that a neighbor had hidden in the salt. Then the prisoners must return to their cells and Charlie, who doesn’t know why or how, get outside of the jail. Trying to return to his cell, Charlie puts alone end to a riot. As a reward, the guards offer a comfortable cell to Charlie.
