Due to a mysterious disease, the genius Iria Akagami has been forced by her family to stay in a mansion on the isolated Wet Crow's Feather Island with only a handful of maids. To keep herself entertained, Iria invites a variety of fellow geniuses to stay as guests in her home, including computer savant Tomo Kunagisa and her unnamed assistant, skilled fortune-teller Maki Himena, famous artist Kanami Ibuki, academic scholar Akane Sonoyama, and renowned cook Yayoi Sashirono. These visits progress as normal until one of the guests is found gruesomely murdered in the night without a single clue as to the identity of the killer or a possible motive. Tensions rise between those on the island as the killer remains at large, and Tomo's assistant takes it upon himself to uncover the culprit's identity before the murderous events progress any further.

With Major Motoko Kusanagi missing, Section 9's Batou is assigned to investigate a string of gruesome murders—seemingly at the hands of faulty gynoids, or sex robots. But when a faulty gynoid leaves Batou a cryptic message, he begins to question the cause of their malfunctions. Suspicions of politically motivated murder and an illegal "ghost" quickly crop up, drawing Batou and his partner Togusa into a perilous web of conspiracy.

As their investigation goes on, the line between man and machine continues to blur, and reality and perception become indistinguishable. Confronting strange and dangerous foes, Batou and Togusa explore a futuristic world filled with machines and living dolls but utterly devoid of humanity.
