Motoko and her squad are finally getting closer to Fire-Starter's broker, but things get tense when they're instructed to take a backseat role on a sting operation.

Freed of her responsibilities with the 501 Organization, Motoko Kusanagi must now learn how to take orders from Aramaki. Someone hacks the Logicomas, and Batou enlists the help of former army intelligence officer Ishikawa and former air artillery expert Borma. Kusanagi also seeks to enlist ace sniper Saito and undercover cop Paz into the new Public Security Section 9.

In a post-apocalyptic future, a group of soldiers is sent to a ghost city to destroy an automated sentry.

The story is set in 2027, one year after the end of the fourth non-nuclear war. New Port City is still reeling from the war's aftermath when it suffers a bombing caused by a self-propelled mine. Then, a military member implicated in arms-dealing bribes is gunned down. During the investigation, Public Security Section's Daisuke Aramaki encounters Motoko Kusanagi, the cyborg, wizard-level hacker assigned to the military's 501st Secret Unit. Batou, a man with the "eye that does not sleep," suspects that Kusanagi is the one behind the bombing. The Niihama Prefectural Police detective Togusa is pursuing his own dual cases of the shooting death and a prostitute's murder. Motoko herself is being watched by the 501st Secret Unit's head Kurutsu and cyborg agents.

Posing as lovers on vacation, Motoko and Batou work to try to stop a terrorist organization whose symbol is the Scrasath. Meanwhile, Togusa investigates a murder of a man who possessed a prosthetic leg manufactured by the Mermaid's Leg corporation.
