The year is 1956.
"Stalin is dead, and a violent regime is beginning to fracture-leaving behind a society where the police are the criminals, and the criminals are innocent. A secret speech composed by Stalin's successor Khrushchev is distributed to the entire nation. Its message: Stalin was a tyrant. Its promise: The Soviet Union will change.
Facing his own personal turmoil, former state security officer Leo Demidov is also struggling to change. The two young girls he and his wife Raisa adopted have yet to forgive him for his part in the death of their parents. They are not alone. Now that the truth is out, Leo, Raisa, and their family are in grave danger from someone consumed by the dark legacy of Leo's past career. Someone transformed beyond recognition into the perfect model of vengeance."
