Synopsis by Bruce Eder
After a troubled, seemingly sleepless night, Perry White (John Hamilton) arrives at work at the offices of the Metropolis Daily Planet, only to find that -- as part of a civic program that he himself approved -- his job, like that of the mayor, chief of police, and every other important figure in Metropolis, has been given over for one day to the most junior male employee on the staff, part of what is called "Boys' Day." As a result, cub reporter Jimmy Olsen (Jack Larson) is now editor-in-chief of the newspaper, and vows to make an impact in his one day on the job by breaking the Legs Lemmy case -- seven years earlier, Legs Lemmy (Herb Vigran) pulled off a major armored car robbery, but the police were never able to find enough evidence to arrest him, and the statute of limitations for prosecuting the crime is set to run out in 24 hours. Olsen prints a front-page story about having new evidence in the case, which shakes up the mobster enough so that he and his two henchmen arrive at the Planet offices and take Olsen and Lois Lane (Noel Neill) hostage. Clark Kent (George Reeves) and Perry White discover what is happening in White's office, but are helpless to do anything about it, for fear of Lois and Jimmy getting hurt -- even Superman breaking in might cause the hoods to open fire.
