In godforsaken Severouralsk-19 there is a small library. There, the quiet librarian Miroslava, closely connected with the influential Bronislavsky family, whiles away her days under piles of books. Miroslava cannot afford to escape from the sleepy town - she needs to take care of her nephew and grumpy uncle, who, due to a terrible incident in childhood, is afraid to leave his house in the swamp.

In the 1960s, the scientist made an unimaginable discovery, the monstrous consequences of which invaded Miroslava’s life in 2015.
