Storyline

The Challengers answer a shipwreck distress call, but find it's a trap. They're pulled through space on a light beam and made captives of a rocket ship space circus. The heroes are prodded through cages and catapulted into a tank to fight Quadro, the Four-Finned Demons. Other alien performers are also captives. As the Challengers prepare for a last stand, Prof learns the atmosphere gives them super-strength. They bombard the circus guards with boulders and disable the ships. The aliens are surprised to learn the circus owners are criminals and promise to send all the captives home.
