MSU history student Nikita Savonin finds himself in 1920 - it was then, according to his thesis, that the future Marshal Tukhachevsky brutally suppressed the Tambov peasant uprising. The question is, why did he need gas for this? Is it because his opponents in that battle were not ordinary peasants, but... real zombies?! Is it possible to influence the course of history if it has taken on inhuman features; is it necessary to do this and how to live knowing the truth that you cannot tell anyone? - these are the eternal philosophical questions that the fascinating science fiction novel by the Schwallner brothers will help answer.
