Uchuu Senkan Yamato III

A stray proton missile from the war between the Galman Empire and Bolar Federation crashes into the Sun, accelerating its fusion and giving Earth less than a year before lethal radiation makes the planet uninhabitable. The Yamato is sent into deep space to find a new world where humanity can survive.

The search carries the crew directly into the Galman-Bolar conflict and reunites them with Dessler, whose people are tied to the Galmans. As political wars spread across the galaxy and the mysterious Queen Ruda enters the struggle, finding a home for Earth becomes inseparable from a conflict that could decide the future of several civilizations.
