A contemporary of our time—a military surgeon, disabled—by the will of fate ends up in his teenage body exactly fifty years earlier. And he has no choice but to continue living the life of an ordinary fifteen-year-old boy in 1964, so he won’t end up in a psychiatric hospital. Concerned about what will happen to his country, he decides to do everything within his power so that the history of the Soviet Union takes a different path. He understands that for this, he must become a person who influences decision-making. And he will manage to become one.
