In the year 2020, Earth suffers from a devastating alien invasion. A large mechanical planetoid suddenly emerges from space and attacks the cities of Earth without reason or communication. With all defenses annihilated, the United Nations corresponds with NASA to make a powerful space fighter known as the SWA-402 Ortega, but the fighter fails to end the war. One of the Ortega pilots - known only by his call sign Fox-A - is killed in action. His bereaved girlfriend Hiroko soon discovers his involvement in the Pandora Project which houses the Ortega's successor: the SDE-201 Aldynes. As the invaders attack the air force housing the near complete Aldynes, Hiroko hijacks one of the ships and throws herself into battle in hopes of getting revenge.
