- Synopsis
- The Challengers are transported by Dr. Oren Gough to the future where the Cosmic Creatures are attacking. Gough explains that the people of Earth will be evacuated, then a volti-ray used to wipe out the creatures. The Challengers volunteer to give their lives by manning the ray, but a man named Lenroy and his friends are also given the privilege. That night, the Challs discover that Lenroy -- who has secretly made the ray harmless to humans -- actually plans to use this opportunity to take over Earth. The Challs fire the volti-rays to destroy the creatures, subdue Lenroy, and return home.
