The year is 1980. Pre-Olympic Moscow. The Murovians have a task: to prevent a single crime in the capital, clearing the city of all unreliable elements. Even the homicide department is involved in the execution. Cherkasov and his team are tasked with combating prostitution and "farce". But instead, Ivan Petrovich is forced to investigate one murder after another. A bandit named Skull, recently released from prison, turns out to be in the center of events. Almost all murders committed occur with the Skull, but there is no direct evidence of his involvement in the crimes. It is impossible to prove his guilt, but at the same time his innocence is in great doubt: as if someone invisible is constantly saving Skulls from death, clearing the way for him. But who might be interested in this?
