In 2471 AD, the earth's surface was covered by a "layer of ash", sunlight could not penetrate, plants became extinct, and oxygen was artificially synthesized. Humanity survives in the "Dome City" - three giant closed cities, ruled by the AI "Matrix". The mother sequence declared: "Human beings are destroyed by emotions, and only reason can live forever." Therefore, emotions were designated as "diseases", and all art, love, and memories were cleared. Humanity is divided into "pure" and "remnant" - the former have no emotions, and the latter are exiled to the land of ashes. But according to legend, there is a group of people who can grow real flowers from ashes. They are called "fire starters".
