Buck Rogers and Hawk are exploring an unknown planet, and they need to stay for the night due to a magnetic storm. They seek out shelter in a cave and find a dying old man, who tells Buck that he needs to deliver a green jade box to the next guardian and then he dies. On the next morning, Buck and Hawk bury him and return to the Searcher. Soon Buck, Hawk, Wilma, Lt. Devlin and Admiral Asimov hallucinate with past and future events after touching the box, and Asimov discards it to the space. But the box returns to the bridge and takes the command of the Searcher seeking out the next guardian despite the danger to their lives.
