It's 2203 and nuclear fusion on earth's sun has forced it's population into underground cities. The Star Blazers seek a planet that will support life, but are drawn into an intergalactic war. They are guided to the lost planet of Gardiana, and given a machine that will stabilize earth's sun. On the way back, they are attacked by the Bolar fleet and saved when the Mariposa/Gardiana spirit guides fighter pilot Flash Contrail in an ultimate act of sacrifice and bravery.
