Earth demonstrates a matter-anti-matter bomb in the Artson solar system at 10 light-years away. In desperation the leader of the colony world enlists the help of the newest Circuit Ship relativistic starship, the Hibiscus 2, to plead for peace before Earth strikes again. Her captain is Tioshi Yamaguchi. He is requested to transport 4 people to Earth to head off any possible warfare with the mother world. Those folks are Richard Ross, a diplomat from Earth but trained as a Circuit Ship astronaut, His wife Lida Rikova, a former Circuit Ship astronaut, Marshal Randell, a former Circuit Ship astronaut accused and convicted of destroying the first Hibiscus Circuit Ship. Dr. Dask Conta, PhD, a physicist that will argue that the Artson colony has no intent or technology to harm Earth in any way.

After 4 years ship-time and 16 years Earth time, they reach the Earth solar system and are intercepted by 6 spacecraft of Earth's interplanetary Space Force commanded by Colonel Jackson Toneman and Major Alexander Barry. The spacecraft escort them to their ultimate destination, the Earth World Delegation Capitol Dome in Greenland, where they commence reasoning with the planet Earth government on their non-aggression plans. But mysterious matter-anti-matter explosions near Earth and the Moon find our Circuit Ship astronauts on the run to Earth Geosynchronous orbit and to the Moon to escape blame. Col. Toneman and Maj. Barry are tasked to bring them back to Greenland but the confrontation at the Moon's L5 Lagrange point brings a stupendous result with momentous and far reaching implications for humanity.
