We is a dystopian novel by Yevgeny Zamyatin completed in 1921. One thousand years after the One State's conquest of the entire world, the spaceship Integral is being built in order to invade and conquer extraterrestrial planets. Meanwhile, the project's chief engineer, D-503, begins a journal that he intends to be carried upon the completed spaceship. Like all other citizens of One State, D-503 lives in a glass apartment building and is carefully watched by the secret police, or Bureau of Guardians. D-503's lover, O-90, has been assigned by One State to visit him on certain nights. She is considered too short to bear children and is deeply grieved by her state in life. O-90's other lover and D-503's best friend is R-13, a State poet who reads his verse at public executions. While on an assigned walk with O-90, D-503 meets a woman named I-330. I-330 smokes cigarettes, drinks alcohol, and shamelessly flirts with D-503 instead of applying for an impersonal sex visit; all of these are highly illegal according to the laws of One State. Both repelled and fascinated, D-503 struggles to overcome his attraction to I-330. I-330 invites him to visit the Ancient House, notable for being the only opaque building in One State, except for windows. Objects of aesthetic and historical importance dug up from around the city are stored there. There, I-330 offers him the services of a corrupt doctor to explain his absence from work. Leaving in horror D-503 vows to denounce her to the Bureau of Guardians, but finds that he cannot. He begins to have dreams, which disturbs him, as dreams are thought to be a symptom of mental illness. Slowly, I-330 reveals to D-503 that she is involved with the Mephi, an organization plotting to bring down the One State. She takes him through secret tunnels inside the Ancient House to the world outside the Green Wall, which surrounds the city-state. There, D-503 meets the inhabitants of the outside world: humans whose bodies are covered with animal fur. The aims of the Mephi are to destroy the Green Wall and reunite the citizens of One State with the outside world. Despite the recent rift between them, O-90 pleads with D-503 to impregnate her illegally. After O-90 insists that she will obey the law by turning over their child to be raised by the One State, D-503 obliges. However, as her pregnancy progresses, O-90 realizes that she cannot bear to be parted from her baby under any circumstances. At D-503's request, I-330 arranges for O-90 to be smuggled outside the Green Wall.
