Dimensional neural networks provoke the development of the abilities of a neuropathic boy, burning out his feelings. To protect his son from illness, his father sends him to the world of Subspace, where one of the most popular playgrounds of the ice-covered world is built. The boy is too young to participate in them, and the young hero cannot get pleasure from the game. But everything changes when he manages to get out of the closed city onto the bloody battlefields of three great armies.
