Is a Story about a girl living in the small Siberian town of Moroz Lesa, in an alternate present-day Soviet Union. Her biggest problem, at least at first, is that she's failing mathematics. Together with her best friends Polina and Alisa, and two unlikely allies from a neighboring class, Svetlana forms a study group under the sharp eye of their terrifying math teacher Sir Sergey. What starts as desperate survival tactics slowly grows into something none of them expected a real, lasting friendship.
