Based on the anime television series from the 1970's (In North America it was called Star Blazers) comes a live action Japanese film version about the fight to save earth from a terrible enemy.

As the story goes, earth's environment has been devastated by an unknown enemy intent on irradiating the planet to kill off all life.  Humans now live underground and Earth Defence forces have received technology from a distant ally which allow them to turn the World War Two battleship Yamato into a space ship armed with deadly weapons.  From there it's a fight to reach the distant planet of Iskandar to receive the technology required to save earth from the evil Deslock.

I'm not sure if the film will follow the original story, but that's it in a nut shell.
