Alex Sedov, a retired Planetary Forces officer, finds himself in a difficult life situation. Career destroyed, health lost, but he is a fighter in life and finds ways to solve problems. To pay for a complete cure, he is forced to conclude a contract with a galactic corporation to work as a hunter-St. John's wort on one of the frontier planets. But in these wild places, the most terrible beast was not a huge bloodthirsty raptor dinosaur, but a man with a machine gun. With weapons in his hands, substituting the shoulders of his beloved and close, the hero will pass a thorny road, difficult trials and amazing adventures. This work is about the natures of the active, militant, hardworking and successful.
