Synopsis

The not-yet-Challengers investigate who sabotaged their plane. Red Ryan escorts an old friend, Johnny Green, in Las Vegas, when a car tries to run them down! Johnny explains HE was the target, not the heroes. Johnny won $300,000 from mobsters but hadn't collected. He was to fly to Vegas with Red. Mobsters planted a plastic sabotage device to crash the plane: plastic to fool metal detectors. The heroes meet the mobsters. A fight brings "Chaos in the Casino". Johnny gets paid and the mob goes to jail. And the heroes finally get their TV appearance as "Challengers of the Unknown!"
