Major Kusanagi Motoko and the Public Security Section 9 find themselves in a constant battle with the newly created wave of technological terrorists and cyber-hackers. But things take a turn once Motoko gets involved in a certain case involving an extremely dangerous "ghost" hacker nicknamed the Puppeteer, as she dives deeper and deeper into the limitless reality of the net, to reach her own startling conclusions.
