Spacegirl Battle 2121 is a retro-style film, shot primarily in 16mm, in which gorgeous spacewomen fight for their freedom in a campy tribute to sci-fi action films of the 60's and 70's. On a distant and rocky planet, Kaya Star attempts to live a peaceful life away from her home world with her mate, Tero. They are discovered by the evil General Arian who dispatches his Cyborgs to capture her for his collection of galactic girls, who are caged in his palace for his Captive Breeding Program. Although Kaya escapes, Tero is captured, and she sets off to free him as well as her space sisters in a series of dance battles while Ava, Queen of the Cyborgs, looks on.
