While Maj. Tomorrow tries to uncover the person who revealed their mission to the press, there is wide unrest around the solar system because the population believes they are doomed. Maj. Vurian's team first finds an inhospitable planet, then one that seems to welcome them. Professor Xoroth comes up with a plan to create a hole in the center of the anit-matter cloud, which would grow large enough in 10 years to allow the solar system to pass safely through it.; Both Maj. Tomorrow's and Maj. Vurian's teams contain a traitor who has been working with a criminal mastermind, Dr. Loglov, to profit from the dire situation. The scientists activate their device and blast a hole in the center of the anti-matter cloud. Maj. Tomorrow and Maj. Vurian confront Dr. Loglov and trick him into confessing.; Maj. Tommy Tomorrow and Maj. Lon Vurian are brought to the Academy of Planetary Sciences, where they are told of an anti-matter cloud that could destroy the entire solar system. They have 10 years to evacuate the 20 billion people from every planet, or find a way to stop the cloud. Maj. Tomorrow leads a crew to investigate the coming cloud, and Maj. Vurian's team seeks a new world on which to relocate. Though the effort is a secret, word somehow leaks to the media.
