 In the late 2100s, the planet Gamilon, a world far beyond Earth s Solar System, declares war on all of Earth. The nations of Earth fight as one against the Gamilons, but one by one, Earth s fleets are defeated. When the nations of Earth refuse to surrender, Gamilon begins bombarding Earth with Planet Bombs, radioactive missiles that look like meteors, which gradually spread deadly radiation all over Earth, forcing what s left of humanity to retreat to underground cities. Queen Starsha of planet Iscandar contacts Earth and promises to provide Cosmo-DNA that can remove the radioactivity and restore Earth to beautiful life. She provides plans to an engine that will allow a brave, young group of technicians to journey more than a hundred thousand light-years to Iscandar, obtain the Cosmo-DNA, and return to Earth within one Earth year. In 2199, an old sea-going vessel is fitted with the awesome engine and launched toward Iscandar. Along the way, the intrepid crew must fight the Gamilons, who are determined to prevent the brave voyagers from saving Earth from extinction.
