In the year 2029, Niihama City has become a technologically advanced metropolis. Due to great improvements in cybernetics, its citizens are able to replace their limbs with robotic parts. The world is now more interconnected than ever before, and the city's Public Security Section 9 is responsible for combating corruption, terrorism, and other dangerous threats following this shift toward globalization. The strong-willed Major Motoko Kusanagi of Section 9 spearheads a case involving a mysterious hacker known only as the Puppet Master, who leaves a trail of victims stripped of their memories. Like many in this futuristic world, the Puppet Master's body is almost entirely robotic, giving them incredible power. As Motoko and her subordinates follow the enigmatic criminal's trail, other parties—including Section 6—start to get involved, forcing her to confront the extremely complicated nature of the case. Pondering about various philosophical questions, such as her own life's meaning, Motoko soon realizes that the one who will provide these answers is none other than the Puppet Master themself.

In the not so distant future, mankind has advanced to a state where complete body transplants from flesh to machine is possible. This allows for great increases in both physical and cybernetic prowess and blurring the lines between the two worlds. However, criminals can also make full use of such technology, leading to new and sometimes, very dangerous crimes. In response to such innovative new methods, the Japanese Government has established Section 9, an independently operating police unit which deals with such highly sensitive crimes. Led by Daisuke Aramaki and Motoko Kusanagi, Section 9 deals with such crimes over the entire social spectrum, usually with success. However, when faced with a new A level hacker nicknamed The Laughing Man, the team is thrown into a dangerous cat and mouse game, following the hacker's trail as it leaves its mark on Japan.
