In the nightmare world of Pyatzonya, in which the famous Chernobyl is far from the most dangerous place, anything can happen. Even a miracle! It was this that saved helicopter pilot Gennady Khomyakov, who found himself in the most inopportune place at the time of the Catastrophe. In a world of stalkers, mechanoid monsters and anomalous traps, Khomyak quickly becomes game, but special game, for which the hunters will first gnaw each other's throats. The former pilot decided to take advantage of this circumstance, because he has his own goal. He is looking for the way to the semi-mythical Chalice, which was told to him by a knight of the Order of the Sacred Knot, betrayed by his brothers. Could Khomyakov have guessed that he himself was more valuable than any artifact?
