In 2029 Niihama City has evolved into a cutting‑edge urban hub. Advances in cybernetics let residents swap limbs for mechanical replacements, while global connectivity has intensified the city"s role in tackling corruption, terrorism, and other threats under Public Security Section 9.
Major Motoko Kusanagi of Section 9 leads an investigation into a shadowy hacker dubbed the "Puppet Master," who leaves victims bereft of memory. In this high‑tech age, the Puppet Master"s form is almost entirely synthetic, granting immense power in cyberspace.
While Motoko and her team employ neural‑interface tools to trace digital footprints, other factions—including covert Section 6—intervene, adding political intrigue and complicating the case. Her partner, a cyber‑lawyer, warns that the Puppet Master"s motives may be rooted in a radical vision of posthuman society. The investigation forces Motoko to confront the blurred line between machine and soul, as each clue reveals deeper layers of control.
As she wrestles with questions of identity, human augmentation, and her own purpose, Motoko realizes that the answers she seeks lie with the Puppet Master himself.
