It is the year Universal Century 0079 and the space colonies have declared war on from the Earth Federation under the guidance of the Principality of Zeon. In one of these colonies, the Earth Federation is storing and testing a new piloted robot for use in the battle against the Principality of Zeon.

The experimental RX-78 Gundam mobile suit is forced into combat with a civilian pilot and an untested crew before it can be transported to the Federation's HQ on Earth. With few resources available against the Zeon's brightest and best, will they be able to escape, let alone deliver the RX-78 to Earth?
