The year is 1984. Aomame sits in a taxi on the expressway in Tokyo. Her work is not the kind which can be discussed in public but she is in a hurry to carry out an assignment and, with the traffic at a stand-still, the driver proposes a solution. She agrees, but as a result of her actions starts to feel increasingly detached from the real world. She has been on a top-secret mission, and her next job will lead her to encounter the apparently superhuman founder of a religious cult. Meanwhile, Tengo is leading a nondescript life but wishes to become a writer. He inadvertently becomes involved in a strange affair surrounding a literary prize to which a mysterious seventeen-year-old girl has submitted her remarkable first novel. It seems to be based on her own experiences and moves readers in unusual ways.
