The main and almost impossible dream of one of the most famous stalkers of the Five Zone, the Diamond Mongoose, was to get rid of the huge diamonds embedded in his body. Having endowed the former military pilot with incredible abilities, they firmly crossed out the possibility of returning to the Big World to his beloved wife and daughter. However, Doctor Svistunov restored hope to the desperate stalker. There's only one thing left to do: get the Lottotron artifact, stolen by the brilliant madman Talerman and hidden in his underground laboratory. During a dangerous search, the Diamond Mongoose finds himself at the center of the intersection of interests of two powerful warring factions. At stake is the further development of human civilization, huge amounts of money, and the lives of the Mongoose himself and his friends.
