Universal Century 0093. The previously missing Char Aznable has revived Neo Zeon and declared war against the Earth Federation government. The Londo Bell unit commanded by Bright Noa is forced to fight alone and unaided against the Neo Zeon forces, which have begun dropping asteroids onto the Earth. Among the Londo Bell members is Amuro Ray, Char’s longtime rival. But their valiant efforts are in vain as 5th Luna falls onto the planet.

Sensing a further threat behind Char’s movements, Amuro heads for the Moon to collect the Nu Gundam, a mobile suit equipped with a psycho-frame. Waiting for him there is its lead developer, Chan Agi. Meanwhile, Bright’s son Hathaway Noa meets a girl named Quess Paraya on his way into space, and is instantly attracted to her.
