Public Security Section 9 is an elite special ops unit that works directly under the control of the Prime Minister. They've been called in to rescue a high-ranking government official from a hostage situation. But something doesn't seem right to Major Motoko Kusanagi.

Kenbishi Heavy Industries has built a state-of-the-art multiped tank. There's only one problem–it's gone haywire and started moving on its own. Section 9 is called in to stop it, as the Self Defense Force will not get involved. Now, it's up to Motoko, Batou, and the rest of Section 9 to stop the tank and figure out what made it go berserk in the first place.

Motoko enters into an online chat room devoted to the Laughing Man to see if she can find any new information on him. What she discovers is a spirited debate among the self-proclaimed "fans" of the Laughing Man, but very little hard evidence.

In a briefing, Aramaki shows a photo of a girl who looks like Eka Tokura, the daughter of Tokura Electronics, who was kidnapped 16 years ago. But there's one problem–the photo was taken two days ago!

Togusa is on the trail of the Laughing Man again, and this time, his investigations lead him towards both a leading micromachine corporation and an NGO called the Sunflower Society.

Despite their best efforts, the remaining members of Section 9 are rounded up one by one by the government forces; only Batou and Motoko are left.

Togusa has been released from jail and he's given papers showing the dissolution of Section 9. Out of work and depressed, he tries to find information on the others, but there is nothing available. Thinking that he has nothing left to lose, he goes to assassinate the man responsible when he is stopped by–Batou!

=A hacker and thief by the name of Cash Eye plans on infiltrating a vault during a party, and Section 9 is called in to prevent it. But there are a number of strange elements in this case that don't all add up.

Plans have been leaked to terrorists that the plutonium recovered from the underground nuclear facility in Tokyo is to be moved. Section 9 is called in to ensure the plutonium reaches its destination, and Gohda is there again.

While field testing new recruits, the Major finds herself hacked, and an old woman tells her a story from her past.

Saito recounts his first run-in with the Major, and how he became part of the group that would eventually become Section 9.

During a scheduled maintenance, the Tachikomas begin to chat away about the Individual Eleven. While talking in their new "forum", Batou and Togusa appear and take one of the Tachikomas - who just happens to be Batou's pet - with them to Spring-8 to look at the scientific evidence gathered on the Individual Eleven.

The government declares martial Law in Dejima, believing that the refugees have a nuclear device and plan to use it to gain independence. When the refugees' connection to Kuze is cut off, one shot begins a bloody war.

The tables seem to be turning in favor of Section 9, but the nuclear missile is still being prepared for launch.
