It is the year After Colony 195, and war between the Space Colonies and Earth has begun. To give the colonies an edge, they send 5 young soldiers, trained to perfection, to earth in the most powerful of Mobile Suits-Gundams. With their arrival, the tide of the war changes as they battle against the Earth forces and the Colonies of their origin

The space colonies have grown tired of the oppressive rule by Earth Government, a corrupt organization ruled by people who have no real interest in the colonists or their well-being. Their rule is unjust and unfair, but not opposed... Resistance forces in the colonies have created five special Mobile Suits (robot-like vehicles) called Gundams. Five young pilots have been selected to sneak these Gundams down to Earth and begin a guerrilla campaign that will end the Earth Government's rule forever. These pilots appear little more than children, but they carry the hopes and dreams of thousands of people with them as they descend to Earth to fight for their freedom.
