USSR, 1946. Mikhail Krasnitsky lives a quiet life near Rostov with his beloved wife Riva. When their firstborn child dies, Mikhail takes it as a sign from above. Under the pretext of business trips, he begins to travel around the Soviet Union, committing a series of murders in cold blood and for no apparent reason. Meanwhile, the secret service manages to detect a connection among these crimes - the victims were all former death camp guards who collaborated with the Nazi regime.
