Rocky Jones and his crew discover a pair of “gypsy” moons, tied together by an atmospheric chain and inhabited by warring civilizations. Bovaro lives with his wife on Posita. The other moon, Negato, is ruled over by Torvak. Negato has used music as a weapon to enslave Posita for years. Bovaro has forced the Orbit Jet down onto the surface and refuses to let them free unless they agree to help him destroy Negato. The Orbit Jet can fly in space, outside the range of Negato defenses that are limited to the atmosphere chain. Through Vena’s friendship with Bavaro’s wife Clolanta, Rocky talks him into supporting a diplomatic mission to forge a peace between the two moons. They fly to Negato and are able to negotiate peace talks. Meanwhile, Cleolanta uses Rocky’s radio silence to trick the Secretary of Space into flying to the planet Ankapol where she has a hypnosis chamber. She cleverly splices together recordings of Rocky’s previous transmissions. She plans to force him to recommend that Ophicius take over some of the United World planets. Rocky appears just in time to prevent it. Throughout the film, Bobby uses parallels in Homer’s Odyssey to suggest how Rocky should proceed.
