In the year 0088 of the Universal Century, the battered assault cruiser Argama arrives at the dilapidated space colony of Shangri‑La for repairs. While the ship is in drydock, junk dealer Judau Ashta slips aboard with the intent of stealing the Zeta Gundam so he can sell it to help his sister. Instead of succeeding, he is forced to join the Argama’s crew. At the same time, the cruiser is being chased by Neo‑Zeon officer Mashymre Cello. To protect his sister and himself, Judau must master the Argama’s newest mobile suit, the ZZ Gundam.
