In year 0079 of the Universal Century, the Earth Federation initiates Operation Odessa—a full-scale assault to retake a major Ukrainian city from the Principality of Zeon. It is a success, and the remaining Zeon forces scatter across the globe. The Earth Federation gains the upper hand in the One Year War and deploys its ground troops around the planet to hunt down the stragglers. As part of the deployments, Ensign Shiro Amada is transferred to Southeast Asia to take command of the 08th MS Team—a special squadron of RX-79[G] Gundam Ground Type pilots. In their first guerilla operation, Shiro's team is tasked with distracting the Zeon forces while Federation ground troops locate a mysterious new Zeon weapon. Everything goes according to plan until Shiro runs into Aina Sahalin, an ace Zeon pilot he met in an earlier battle, during a skirmish. Their reunion weakens his resolve to continue fighting, and now the young commander Shiro must prove his loyalty to the Federation—or be branded a traitor. [Written by MAL Rewrite]

Tricked into assassinating his own prospective father-in-law, righteous samurai Raizou Kurima is overwhelmed with guilt. In order to reclaim his honor, Raizou swears vengeance on the lord who gave him those misleading orders. In his pursuit, he is aided by self-proclaimed merchant-of-all-trades Yuuen Usui, who is actually one of the Revengers—assassins who seek justice for the wronged and dispense bloody revenge on their behalf. Tragedy seems destined to follow Raizou as he becomes increasingly intertwined with members of the Revengers. As he begins working as a vigilante alongside them, the complicated web between the corrupt Japanese political elite, the unscrupulous Europeans, and the Revengers gradually reveals itself. The more entangled he becomes in these affairs, the more Raizou realizes that justice is as deceptive as the honor that he sought to redeem.

The anime film will feature the familiar characters from the franchise now grown up, and reuniting to construct a campsite.
