Year 70 of the Cosmic Era. The Coordinators, a group of genetically enhanced humans, have moved into colonies orbiting the Earth. But that hasn't quieted the tensions between them and regular humans; the conflict soon escalates into a full-scale war. On the neutral colony of Heliopolis, Kira Yamato, and his friends are going to school and just being kids. But when the ZAFT commando forces attack, Kira's life changes forever.

Left with no choice, he and Federation officer Murrue Ramius are thrown into battle in a prototype mobile weapon, which Kira christens "GUNDAM." Now, Kira must defend himself and his friends from his own people. For, unknown to anyone else, Kira is a Coordinator. And the enemy he faces on the battlefield is his childhood best friend, Athrun!
