Universal Century 0153. During the war between the League Militaire and the Zanscare Empire, Uso Ewin while alone on a reconnaissance mission happens upon the Zanscare Empire's Newtype squad, and finds himself blind-slighted by a Zoloat, and comes under attack by the mysterious Mobile Armor Zong. However he finds himself rescued by an old junk dealer Grey Stoke (the incognito hero of the First Neo Zeon War, Judau Ashta). The pilot of the Zolat, who was also rescued alongside Uso is revealed to be a young girl named Kamui Gian, who is given a special V2 Gundam to help fight alongside Uso and Grey to seek out the Zong and destroy it. But can the trio stop a Mobile Armor as powerful as the legendary Zeong that can create more of itself and discover what Grey Stoke plans to do with a colony filled with Newtypes?
