A Superman impostor is going on a crime spree when Clark and Lois meet up with him at the opera where Clark has fallen asleep. Lois sneaks out and catches the crook and rips the "S" off his costume, making her believe it really is Superman. Clark changes and the two Supermans get in a tussle on the roof, where the real one deflects bullets. Back at the crime layer Superman is locked in a chasm with a desk over it while the criminals get away by making a hole in a vault. Superman escapes and steps between their car and a police car with Lois inside. Later Clark is dozing when Lois comes back to the office to type up her story.
