A mystery between the story of the silver arrows and this one is missing. All we know is that Clark has just come from an adventure with the Inca indians of South America. Back in the offices of the Daily Planet, he is about to learn of a new mission from Perry White. Known to no one, Perry has become an agent of the Secret Service, and will open the door for many adventures to come for the man of steel.
Elsewhere, we are privvy to the jail break plans of the Yellow Maskk. The criminal mastermind, and first arch rival of Superman has been safely behind bars for more than a year. What evil plans will he have in store for our hero, and the national security of America? The roar of Tommy guns signal the escape, and beginning of the police manhunt.
Clark and Perry discuss the escape, but what role should they play in the capture of the Yellow Mask? The police ought to have the matter under control without them. Instead, they talk about a rash of sabotage in munitions plants, and ships in the harbor. Why is the Yellow Mask phoning the Daily Planet, and what is his warning threats about?
