Aboard the Minerva, Chairman Dullindal receives shocking news. The ruins of Junius Seven, the PLANT that was destroyed in the infamous Bloody Valentine incident and where the armistice treaty was later signed, have left their stable orbit and begun falling towards Earth.

ZAFT swiftly dispatches a demolition crew commanded by Yzak Jule to break up the remnants of Junius Seven, but it becomes clear that this is no mere accident when the demolition crew is attacked by what appear to be ZAFT mobile suits. As the Minerva arrives at Junius Seven to provide support, Athrun volunteers to join the battle.
