A stowaway sneaks aboard a ship departing on a cruise down the Vistula River. The captain takes him for a Communist Party cultural coordinator and the intruder gladly adapts to his new role, immediately setting to work at manipulating the passengers and crew into silly and vaguely humiliating games. Before long, Tym has got everyone under his thumb and created his own comedic dictatorship.
A parliament member's sixteen year old daughter Agatha falls in love and runs away with a convicted young tramp, while her father uses his friends in the government and police to brutally break their happiness.
The film is a story of a young man coerced into undercover work for the police, in return for their dropping of charges against him. He is to befriend a leader of a gang of juvenile delinquents who plans big robbery of a jewelry store. The scheme works and the gang is caught in the act except the gang leader.
