It's 1934, and the assassination of Sergei Kirov, Leningrad's Communist Party chief, has rocked the Soviet Union. When an up and coming young Party official is assigned to investigate, it looks like an open and shut case.

Because he has stumbled upon these secrets older than humanity itself, Yezhov must be eliminated. But first he must be led to commit acts that will ensure that history will forever remember him as a vicious criminal.
