What could a demoted FSB lieutenant colonel, a writer and a professional killer have in common? Fate brings Oksana Varentsova, Oleg Kraev and Semyon Pestsov together in one of the regional centers of the Leningrad region - a town called Peshcherka, located at the edge of vast swamps.

And there is less and less time left...< /p>
