GRU agent Zotov, nicknamed “Chistodel” (Clean Work), has been tasked with finding an electronic drive where criminals who carried out a large-scale financial fraud of the state have stored valuable information. The case is complicated by the fact that the fraudsters include the minister and the vice-premier—whose capabilities, as everyone knows, are practically limitless. While carrying out the assignment, Zotov literally balances between life and death, using all his skills and old connections. He doesn’t even suspect that, at the very same time, a split is already brewing inside the criminals’ gang.
