A new assignment for Андрей Черников, our contemporary who ends up in the middle of the past century: to be sent to January 1940, to the place where “beyond the river, Sestroya, the front in the snow is up to the waist,” in order to save—during this “unremarkable” war—an apparently insignificant person: an ordinary young Red Army soldier. And only Черников’s handlers from the distant “unlit” future know what use a simple Soviet guy will be if he becomes a great scientist.
The “mission to the past” is supposed to be brief—just four days. But for Андрей, that time will be enough not only to carry out the main task, but also to accidentally mix up the plans of those who intended to turn the Soviet-Finnish “Winter War” into something bigger.
