Synopsis:
Superman returns to the Daily Planet after completing a mission. Supergirl meets him there and reveals his secret identity to Perry White. Later Batman reveals his secret to Lois Lane and Lori Lemaris proves it to Jimmy Olsen. Superman feels betrayed by his friends, but the three members of the Daily Planet staff agree to keep the secret.

Superman decides to remove the knowledge from their minds. He invents a machine, but it doesn't work. After using the machine Lois, Jimmy, and Perry blackmail Superman. However, Superman discovers that his friends are all androids sent by the Superman Revenge Squad. The Man of Steel rescues his real friends. The Squad destroys the androids after their failure. Superman then explains to Lori, Batman, and Supergirl how he discovered the androids when they didn't tear up from exposure to tear gas.
