The book is devoted to guerrilla and scout BOB Alexander Ivanovich Kozlov, who on the instructions of GUKR SMERSH NKO of the USSR was embedded in the intelligence Abverkomandy-103, which operated under the code name "Saturn". Thanks to a clever, subtle and bold secret struggle with the German special services, Kozlov practically ruined Saturn's efforts to obtain objective intelligence about the Red Army. However, after the war, the officials almost made a traitor out of the hero. He undeservedly served 3 years in Karlag. And only in the mid-1960s, the black streak of persecution turned into fame after the publication of publications and films about his heroic activities behind enemy lines.
