Master Of The Power Ring! Acting as chairpersons for a charity bazaar gives Carol Ferris an opportunity to spend more time with Green Lantern. While out working in the Kalahari desert and clearing sand that poses a threat to development, he uncovers a strange meteor which he brings back with him to Coast City to be examined. While on a dinner date with Carol, Hal spots a meteor on a collision course with Earth, and stops it. While in space he spots another meteor which he takes with him back to Earth. His date with Carol is interrupted once again when a news bulletin about a deadly radiation from the planet Jupiter may threaten the Jupiter probe. Going off into space once more, Hal detects the source: yet another meteor, which he takes and brings back with him to Earth.
Hector Hammond, who has used his super intellect to escape from prison, wants to get at these meteors and so uses his super-mind to take control of scientists at the science institute to bring them to him.
