On the far flung technologically advanced world of Titan, mammals similar to Earth's rose to prominance. Great Corporations grew and merged and bought each other out until they owned everything, including the government. A corporatacracy rose up and the people have now chafed under its rule for several generations. From out of the wastelands of Gunrock, where the last free kingdom fell several generations ago, come three adventurous brothers with a mysterious past. They meet along the way a reclusive girl with her own dark history and several others bent on leading a rebellion. Wanting nothing more to get a ship and escape Titan and its oppressive government for good, the brothers' antics inadvertantly sow the seeds of rebellion while drawing the ire of the local governor, who decides to send his troops in to squash it. Now the brothers and their allies must band together.
