After Kusanagi Motoko, Bart and Togusa, who was a detective, became partners. Recently, there have been many cases of robot dolls killing their owners and then committing suicide. Since the families of the victims did not file a public prosecution, and there were politicians and public security officials among the dead, Public Security Section 9 sent Bart's team to investigate the case. The murderous dolls are all Hadley models produced by the Desolate Zone Company. At the request of some customers, this model also has the function of a playmate of the opposite sex. Bart started with the murder of the shipping officer of the Desolate Zone Company and was involved in a battle with the gangsters. During the period, someone invaded his brain and caused him to self-mutilate. Bart decided to go straight to the Desolate Zone headquarters. He and Togusa visited the hacker Kim on Etorofu Island. The latter set a system trap. Fortunately, Motoko warned Togusa to avoid being controlled. Relying on Kim's clue, Bart boarded the factory ship set up by the Desolate Zone Company on the sea. Motoko came to his side again and fought side by side with him.
