Aleksandr Turetsky is a senior investigator assigned to particularly important cases of the General Prosecutor's Office of Russia. Secular manners, masculine charm, detective talent - everything is right. However, the gentleman's set of detective does not prevent Turetsky from following the trail in the mud and swamps of Russian roads, which, as you know, lead to the highest ranks offices. Corrupt Russia, a country of financial scams, stock market manipulations and bloody criminality, is successfully ruled by bankers, deputies and godfathers until Turetsky appears. He cannot be cheated, bribed or blackmailed because he is too smart, too independent and too honest. The invulnerable Turetsky is simply doing his duty.
