The defenders of Earth, the Gray Panther Army, saved the Earth from an invasion from the Libra Alliance on January 6, 2128. The jubilation was short-lived as Earth's defenders found out there was a second deadlier fleet that would arrive at Earth in about two years. The Gray Panther Army consisting of ancient veterans, who have been enhanced through nanite technology to once again be young men and women, are forced to expand their ranks to include even the young. The Gray Panthers enlist the services of Matt Andrews and his team of crack flyers, "Matt's Marauders". Their mission: to fly captured fighters deep in enemy space from a captured raider to buy Earth time as defenses are built up and the fleet increases in anticipation for the looming invasion.
