No one understood how our contemporary, a reserve officer and history teacher, ended up in his own past. Back into the body of a seven-year-old boy. And again in the times of triumphant, developed socialism, when, as far as our hero remembered, there was an order of magnitude more joy and happiness all around. Everything is so, but, in the eyes of an adult, in a sunny country called “Childhood”, it turns out that not everything is so perfect, as memory previously suggested. It turns out that there is also meanness and greed here. There are thieves, bandits, and scammers of all stripes, although as a child you never noticed them before. And now we need to do something about it. It is simply necessary to fight this, because evil knows no barriers in time. And enemies appear in the visual range again. Cruel and treacherous. Smart and merciless. In addition, some of them remind our hero very strongly of someone else. So a seven-year-old hero with two higher educations, with combat officer experience and a memory burned by the dashing post-perestroika years, begins his little war, taking as allies no less... State Security Committee of the USSR. And unexpectedly finds new friends there. Yes, those for whom you can risk your life!
