It is Universal Century 0087 - seven years since the end of the One Year War. The Earth Federation has formed an elite special operation unit named the Titans, whose main objective is to hunt down renegade Zeon supporters and anti-Federation insurgents. However, the Titans soon begin to commit atrocities far worse than the past acts of the Principality of Zeon, and the Anti-Earth Union Group (AEUG) is formed to put a stop to them. One day, a small AEUG team sneaks aboard the space colony Side 7 in order to steal its new Gundam Mk. II, and leaves with Kamille Bidan
, a Newtype ally. Their set goal will be the attack on the Titans' Earth headquarters at Jaburo, but can they succeed or are they playing right into the Titans' trap?
