Cyborg detective Batou is assigned to investigate a series of murders committed by gynoids—doll-like cyborgs, which all malfunctioned, killed, then self-destructed afterwards. The brains of the gynoids initialize in order to protect their manufacturer's software, but in one gynoid, which Batou himself neutralized, one file remains: a voice speaking the phrase "Help me."

In 2030 AD, even if the intention to run around as light and electrons is concentrated in one direction as the computerization becomes generalized and the information network becomes more sophisticated, by the time the "lonely person" becomes an "individual" as a complex. Is an era when it is not computerized. It depicts the activities of the "Public Security Section 9" (commonly known as "Ghost in the Shell"), which was established as an independent counterintelligence unit under the direct control of the Ministry of Home Affairs to counter complicated crimes. There are a wide variety of top-secret missions such as cybercrime investigation, terrorism deterrence / arrest, VIP protection, and corruption detection, but one incident emerges as it is carried out.

塔奇克馬的日常 (英語：Ghost in the Shell: Tachikoma Days，日語：タチコマな日々, Tachikoma na Hibi;也被稱之為Tachikoma Specials) 是一部隨DVD附送的特典性質動畫短片，其出現在以DVD版本發行的電視動畫版攻殼機動隊的每話最後部分，就風格而言是部輕鬆搞笑的作品，作品的主角就是公安九課所使用的思考戰車塔奇克馬(Tachikoma),其內容上除了對部分劇情的哲學思考外也有起到對TV版動畫補完的作用.如今已經播放的攻殼機動隊 Stand Alone Complex以及第二部攻殼機動隊 S.A.C. 2nd GIG的每集的最後均有該短篇的身影，每集長度約為1分鐘左右.
