Berlin, November 1945. Yuri Nosenko, a Russian army officer awaiting execution for a crime he didn't commit, is released from an NKVD prison and sent to Berlin with orders to find and kill Heinrich Müller, head of Gestapo. Müller has top secret Soviet documents that prove Joseph Stalin ordered the Katyn Forest Massacre of 15,000 Polish officers. He aims to swap them for immunity from prosecution as a war criminal and for sanctuary in the West. Their disclosure could shatter the flimsy postwar peace between the United States and the USSR, even sabotage the Nuremberg War Crimes Trials. Trapped between American and Russian occupiers, pawn of the NKVD, Nosenko stumbles through the ruins of Berlin searching for Müller. Haunted by the horrors of the Eastern Front, he's consumed by memories of his vanished wife and children whom he has vowed to find. Dogged by Russian assassins, Nosenko's dual quest evolves into a perilous and deadly trek that propels him to a final reckoning with his past, his future, and the days of killing.
