Two space cadets investigate the wreck, and discover a beautiful woman, dead, with a message for Earth: if Earth can send a ship to Iscandar, Queen Starsha of Iscandar will give Earth technology that will neutralize the radioactive contamination on the planet, and save humanity. In the middle of a losing battle against the Gamilon fleet, a spaceship from the planet Iscandar arrives and crashes on Mars.

The Gamilan fleet (Gamilon in the Star Blazers dub) is superior to humanity's few remaining warships, and the extinction of humanity is likely within a year. In 2199, the surface of the Earth has been bombarded into an uninhabitable radioactive wasteland by an alien race from the planet Gamilas.
