Boris Ivolgin is a former paratrooper with extensive combat experience. Only he fought in the Syrian sands. For the last two years, the young man has been living his quiet and calm life in his native Yalta. He leads excursions in the mountains, studies psychology and wants to forget his past, in which there were too many deaths and losses. But what to do when the past reminds itself of itself? Reminds and demands to repay the debt. A debt of brotherly honor and a debt of life. The former sergeant major of the airborne reconnaissance company, Ivolgin, will have to answer this difficult question. And where this new road will lead him, only time will tell, as well as the guy’s unusual skills. Two years were not in vain. Boris learned a lot by mastering the latest techniques of modern psychology. But will all this help him? After all, it’s March 2022, and a new front has opened on the threshold of his native Crimea, where experienced fighters are needed more than inexperienced psychologists.
