My war isn't over! One mobile suit infantryman's personal battle resumes as a red fire blazes again in his eyes! Captain Grahalt Mills, commander of the Legium nation's special forces "Jackal" unit, utilizes the most advanced mobile infantry exoskeleton in existence, the SAA (Special Assault Armor). With the last line of defense faltering against Dragnov's pressing forces, the Jackals are deployed in a last ditch attempt to hold the line and succeeded at destroying all opponents in their sector! In a bizarre turn of events, Mills' own subordinates of the Jackals all frame him for the murder of several Legium soldiers, severe war crimes which sentence him to be executed for treason. With an eye for vengeance, Mills escapes from prison on his own and tracks down the old members of the Jackals to figure out why he was betrayed.
