Flying a single engine plane over Nevada, Fireball is surprised by a biplane making a diving run at him. Intrigued, he lands at the nearest airport and heads into the small town nearby. There he will find out that the Federal Bullion Reserve is nearby, its head of security is an old FBI friend who is expecting him, and the Cat is lying in wait to kidnap him and replace him with a disguised henchman.
