Ghost in the Shell: SAC_2045 (攻殻機動隊 SAC_2045) is a Japanese original net animation (ONA) series based on the 1989–91 manga series Ghost in the Shell by Masamune Shirow, set in the Stand Alone Complex sub-continuity.
The first season premiered exclusively on Netflix worldwide on April 23, 2020, with a second season being released on May 23, 2022.

Premise
In the year 2045 (11 years after events of Solid State Society), after an economic disaster known as the Simultaneous Global Default which destroyed the value of all forms of paper and electronic currency, the "Big 4" nations of the world are engaged in a state of never-ending "Sustainable War" to keep the economy going. In this world, Motoko, Batou, and other members of Public Security Section 9 have contracted themselves out as mercenaries under the group "GHOST," using their cybernetic enhancements and battle experience to earn a living while defusing hot-spots across the globe. However, the emergence of "Post Humans" and a conspiracy uncovered by former Chief Aramaki force Section 9 to reunite.
