When mankind beams a radio signal into space, a reply comes from ‘Planet G’, in the form of several alien crafts that splash down in the waters off Hawaii. Lieutenant Alex Hopper is a weapons officer assigned to the USS John Paul Jones, part of an international naval coalition which becomes the world's last hope for survival as they engage the hostile alien force of unimaginable strength. While taking on the invaders, Hopper must also try to live up to the potential that his brother, and his fiancée's father—an Admiral—expect of him.

In the year 2220 A.D., the Earth Federation launches a plan to evacuate Earth when discovering that a travelling black hole capable of destroying anything in its path is on course towards the solar system. As the people on Earth prepare to relocate to planet Amare, whose ruler offers refuge, the tyrants known as the "S.U.S. Empire" attack the first Earth evacuation fleet. After learning that his wife Capt. Yuki Mori-Kodai disappeared in the battle and that legendary space battleship Yamato has been fully rebuilt, Susumu Kodai accepts command of the ship as he intends to not only help humanity once again, but also find Yuki in the hope of helping his relationship with his daughter Miyuki, who puts the blame on him for her mother's disappearance. But in order to fullfil the mission, the Yamato must go through battles against the SUS Empire, who intend to spoil humanity's hopes of finding a new place to live in and turn Earth into energy for their own selfish needs.

The year is 2199. The human race has been crushed in their war with the Gamilos, driven into underground cities by the invader's assault. Scientists estimate they have only a year left. The young officers Susumu Kodai and Daisuke Shima receive a mysterious capsule from a ship that made an emergency landing on Mars and return with it to Earth. It contains humanity's last hope: the planet Iscandar on the other side of the Magellan Galaxy has the technology to defeat the Gamilos and restore the planet. The space battleship Yamato is entrusted with this task, but they have only one year before humanity ends.
