A thief, acting on the orders of a crime boss, commits a series of crimes dressed like Superman. Although the police have been fooled and are searching for Superman, Lois Lane believes he is innocent. While covering an opera with Clark Kent, Lois encounters the impostor and tears off the 'S' logo off his costume, leading her to believe Superman had indeed gone rogue. When Clark catches on to what happened, he chases down the impostor as Superman to bring him and his boss to justice.
