Soviet Union, 1956: Stalin is dead. With his passing, a violent regime is beginning to fracture - leaving behind a society where the police are the criminals, and the criminals are innocent. The catalyst comes when a secret manifesto composed by Stalin's successor Khrushchev is distributed to the entire nation. Its message: Stalin was a tyrant and a murderer. Its promise: The Soviet Union will transform. But there are forces at work that are unable to forgive or forget Stalin's tyranny so easily, that demand revenge of the most appalling nature. Meanwhile, former MGB officer Leo Demidov is facing his own turmoil. The two young girls he and his wife Raisa adopted have yet to forgive him for his involvement in the murder of their parents. They are not alone. Now that the truth is out, Leo, Raisa and their family are in grave danger from someone with a grudge against Leo. Someone transformed beyond recognition into the perfect model of vengeance.
