The film is about two sisters named Yoshie and Kikue Kasuga, Geishas who get abducted by a steel manufacturer in an attempt to transform them into murderous cyborg assassins.
The film starts out with an assassination attempt on a political candidate by a Geisha (that turns out to be a robot) and two scantily-clad women wearing Tengu/Goblin masks.
The goblin-clad women violently (and phallically) take out the body guards (notably shooting shuriken out their butts) as the politician is menaced and wounded by the robot geisha who has a circular saw blade in her mouth.
Suddenly, another person named Yoshie (Aya Kiguchi) appears, reveals herself as a robogeisha, and destroys the villainous robot.
Despite her klutziness, Kageno is impressed with Yoshie's beauty and becomes more interested when he witnesses her display of superhuman strength when threatened by Kikue.
They are told that Kageno Steel seeks to use them to kill terrorists and other national threats in an effort to create an "Ideal World".
The story reaches a turning point when Yoshie is sent on a mission to kill a small group of elderly people and their young caretaker living near the Kageno Steel building.
Yoshie barely makes it out of the building after an Explosion from the Suicide mission and her body is recovered by the senior group and she is rebuilt by the leader, who used to work for Kageno Steel.
The group then heads off to confront Kageno and his father and force them to return their cyborg relatives or reveal the bomb plot to the authorities.
Yoshie launches an assault on the robot-castle, defeating her former geisha sisters and the goblin girls (in a battle featuring a butt-sword duel).
