Meanwhile, Clark Kent knows the truth—Superman isn’t behind these crimes. When Clark tracks the impostor to the opera, the real showdown begins. But while the phony Superman is just a small-time crook, a powerful crime boss lurks in the shadows, pulling the strings. Can Superman clear his name and bring the mastermind to justice?
