In a lawless solar system colonized in 2111, Isaac Godonov forms the J9 team, consisting of himself, Blaster Kid, Stephen Bowie, and Angel Omachi, along with their robot Braiger, to combat evil forces. This team undertakes missions rejected by the helpless police, but always for a fee. Meanwhile, a scheme in the Nubia sector on Earth aims to obliterate Jupiter to generate 30 new habitable planets, risking Earth's annihilation in the process.
