As a result of the dwindling living space on Earth, humanity poured into the vast expanses of outer space. Centuries passed until the remote Duchy of Zeon finally proclaimed its sovereignty. However, this declaration of independence ignited an interstellar conflict that would claim countless victims in a very short time.

In the year of the Universal Century 0079, the experimental combat robot RX-78 Gundam is to be transported to Earth. But before the Federation's ships can reach their destination port Jaburo, they are intercepted by the Zeon armed forces. Only the young Amuro is now capable of piloting the unpredictable Gundam and putting an end to the senseless battles.
