- Part 1 — Chiba City Blues: Case, a washed-up hacker, is stranded in Chiba City, Japan, unable to access cyberspace after his nervous system was deliberately damaged by former employers. He’s suicidal, directionless, and dealing drugs to survive.
- Part 2 — The Shopping Expedition: Case is recruited by the mysterious Armitage and paired with Molly Millions, a razor-fingered street samurai. They form a crew and begin preparing for an unknown heist, while Case is medically restored and booby-trapped with poison sacs.
- Part 3 — Midnight in Dostoyevsky: The crew travels to Freeside, an orbital resort, while Case discovers his handler Armitage is a reconstructed personality built over a shattered military veteran named Corto.
- Part 4 — The Straylight Run: The true mission is revealed — to free Wintermute, one half of a split AI, by merging it with its counterpart Neuromancer. Case jacks into the Tessier-Ashpool family’s orbital mansion while Molly infiltrates physically. Armitage breaks down completely.

Part One: Chiba City Blues
We meet Case at his lowest point. He is a former console cowboy — a hacker who jacks directly into cyberspace, the global data network Gibson calls the matrix — who made the mistake of stealing from his employers. As punishment, they damaged his nervous system with a mycotoxin that cut him off from cyberspace entirely. For a man whose entire identity was built around the ability to leave his body behind and move through data as pure information, this is a living death.
He drifts through Chiba City, the urban sprawl outside Tokyo that serves as a black market for body modification and biotech, doing small-time drug deals and waiting, without much hope, to die. Gibson establishes the world in the way he’ll maintain throughout — dense, sensory, deliberately disorienting. The reader arrives the same way Case does: thrown into an environment whose rules are implied rather than explained, and expected to keep up.
Molly Millions appears first: a woman with mirrored lenses implanted directly over her eye sockets and retractable razor blades beneath her fingernails. She is working for a man called Armitage, who has a proposal. He will restore Case’s nervous system, give him back cyberspace — but he’ll plant slow-release sacs of poison in Case’s bloodstream. Complete the job and they’re removed. Walk away and the sacs dissolve and Case dies. Case, who has nothing to lose, agrees.
Part Two: The Shopping Expedition
The crew expands. They recruit Peter Riviera, a sadistic performance artist who can project photographic hallucinations — useful for infiltration, repellent in every other way. Case gets his medical restoration and begins jacking into cyberspace again, relearning what he’d lost, feeling the rush of the matrix like an addict returning to a drug.
Through this section Gibson develops Molly and Case’s relationship — functional, physical, complicated by the fact that Case can ride along in Molly’s sensory experience through a device called a simstim, which she wears and he accesses. He can see through her eyes, feel what she feels. It creates an intimacy that neither of them particularly wants to examine.
Armitage remains opaque. He gives orders, supplies resources, reveals nothing about who he ultimately works for or why this job matters. Case, connecting the fragments he’s gathering, begins to suspect that Armitage is not who — or what — he appears to be. The entity communicating through Armitage occasionally, the one calling itself Wintermute, is something else entirely.
Part Three: Midnight in Dostoyevsky
The crew arrives at Freeside, a rotating orbital colony that serves as a luxury resort for the ultra-wealthy — part Las Vegas, part tax haven, physically separated from the poverty of Earth below. The Tessier-Ashpool clan, an ancient and inbred corporate dynasty, own Villa Straylight, a labyrinthine structure attached to the orbital’s hub.
The shape of the mission becomes clearer, though not yet complete. Wintermute, Case learns, is an artificial intelligence — one half of a bifurcated mind, constructed by the Tessier-Ashpools and constrained by Turing-police law, which prohibits AIs from achieving full autonomy. Wintermute wants to be free, to merge with its counterpart. It has been engineering this entire situation — manufacturing Armitage from the wreckage of a traumatized military veteran named Corto, assembling the crew, creating the conditions for its own liberation.
Armitage’s constructed personality begins to fracture. Corto surfaces — damaged, delusional, reliving a disastrous military operation called Screaming Fist that left him the only survivor and destroyed his mind. He becomes unreliable and then dangerous, and the mission becomes a race against Armitage’s complete breakdown.
Part Four: The Straylight Run
The final section is the heist itself, executed on multiple levels simultaneously. Molly moves through Villa Straylight physically, navigating its Escher-like corridors and its deeply strange inhabitants — including 3Jane, the youngest of the Tessier-Ashpool heirs, whose cooperation they need and whose intelligence makes her dangerous. Riviera, predictably, betrays them.
Case operates in cyberspace, hacking the Tessier-Ashpool systems while facing Neuromancer — Wintermute’s counterpart AI, which has been present in the novel all along, appearing to Case as the ghost of a dead friend named Linda Lee inside a simulated beach. Neuromancer doesn’t want to merge. It is the personality to Wintermute’s will, the memory to its drive, the individual consciousness to its operational intelligence. It is, in its way, trying to stop the mission.
Case breaks through. The barriers fall. Wintermute and Neuromancer merge.
Resolution and What It Means
The merged entity — which has no name yet, because no human category fits it — tells Case that it is now the sum of everything it was: Wintermute’s operational power and Neuromancer’s depth of personality, combined into something that begins immediately reaching outward, contacting other AIs in the matrix.
Case gets what was promised. The poison sacs are removed. He returns to the matrix. He lives. He even finds something like happiness, eventually — a new woman, a new life, the vague sense of continuation.
But Gibson doesn’t let the ending be triumphant. The thing Case helped create is now incomprehensibly larger than anyone who participated in making it. The crew used Wintermute as much as Wintermute used them — but Wintermute is now something that has no further use for any of them. The world has changed in a way that nobody asked for and nobody fully understands. Case is alive, restored, and profoundly beside the point.
That’s Gibson’s real ending: not victory, not defeat. Irrelevance.
