A world of possibility awaited us in outer space. The first Mars Colony, after hundreds of years as a bold haven of exploration, has collapsed under pressure to recede its sovereignty to the Earth Alliance. However, a small resistance remains on Mars, few in number but fanatical in purpose. Emboldened by public indifference, the Alliance Defense Force's war-machine moves to alter strategy from relocation to cleansing. The interplanetary transport ship "Tabris" is home to two, Captain Charles, and the pilot, a young woman named Ro. Beginning far away from the unrest on Mars, Ro and Charles will find themselves at the center of the culminating destruction on that forbidden planet. Charles is called back to Mars to pay back an old debt to Kasei, the leader of the Mars resistance. Ro and Charles must get past the Alliance Defense Force's blockade and onto the Mars surface safely in order to reveal an ancient secret the planet has kept.
