Following the decisive battle against the Titans, AEUG's Argama crew (along with a new bunch of kids), has little time to regroup as a new threat looms in the horizon: Haman's Neo Zeon.

Judau Ashta, a junk collector from Side One colony Shangri-La, decides to steal the Zeta Gundam from the Argama. Instead, he finds himself helping the AEUG from the pursuit of Axis' Mashymre Cello. With the loss of its ace pilot Camille Bidan, Captain Bright Noa persuades Judau, along with his friends, to join the Argama and pilot its mobile suits, putting an end to the threats of Neo Zeon.—heyitsnuel
