By the middle of the third millennium, humanity had created a beautiful and great civilization. This is a world of floating cities, floating houses, artificial exoplanets capable of flying to the edges of the universe like interstellar cruisers, and formidable allies. On Earth, every person can realize his dream or simply lead a life full of pleasure, but people still find the opportunity to lose hope or make one mistake after another. While the planetary authorities are holding back the progressive plans of the radicals, Major General Nikita Larsky, tired of his service, investigates a complicated murder , in which an alien from the Far Reaches is accused.

Is this strength or weakness, hope or the impending collapse of a powerful civilization of mankind?
