Lake Horseshoe, hidden from prying eyes among impenetrable anomalies, haunts lovers of easy money. After all, in the middle of the lake, in a floating house, lives an old stalker who, according to rumors, has accumulated many rare artifacts. But the Zone doesn’t give anything for nothing. Neither the “Freedom” stalkers, who entered into a temporary alliance with the bandits, nor the “Duty” stalkers, eager for revenge for their dead comrades, nor the military stalkers, who were ordered to find and return one person at any cost. The zone will gather them on the shores of the lake and give them the opportunity to find out which of them is worthy of the Horseshoe treasures. But only two mutants who find themselves in the center of events, and still consider themselves human, understand that real treasure cannot be carried in a backpack.
