At the height of postwar Soviet Russia, WWII hero and MGB officer (precursor to the KGB) Leo Demidov is denounced, demoted, estranged from his wife Raisa, and sent to the Ural Mountains because of the ambitions of an inferior officer. In the little town of Voualsk, Leo discovers that all is not well in Stalin’s paradise as he investigates the suspicious death of a local child. Haunted by childhood memories, Leo tries to solve a series of related child murders, restore his relationship with his wife, and keep his growing doubts about the Soviet cause under wraps from prying eyes.
