Cosmo Woman, the last warrior wielding Cosmo Force, stands against Emperor Kreutz, the evil ruler seeking to dominate the universe. Her real father, Mighty Black, once served under the emperor but has now been transformed into part of his oppressive regime. Cosmo Woman carries two missions—defeat Emperor Kreutz and awaken her father Mighty Black once again. She fights alone, putting up a valiant struggle, but ultimately falls into the emperor's hands. Needing her powers, Kreutz attempts to turn her to his side using torture and brainwashing. Bound tightly, immobilized completely, she is forced to undergo electroshock brainwashing. Despite her pleasure centers being numbed, she must endure and overcome the agony. Emperor Kreutz modifies her father Mighty Black's penis into a special electroshock brainwashing device and thrusts it into Cosmo Woman. Her body involuntarily responds with sensation, yet the brainwashing fails. She is then transformed into a resident of Jud, the most impure planet in the universe. The genitals of Jud's inhabitants are diseased—any contact causes infection and unbearable itching. Cosmo Woman now faces a life-or-death crisis. What will become of peace in the universe? The story leads to an emotional final scene.
