An old Russian grandmother or "babushka", who took part in the Battle of Stalingrad, sacrificed everything for her children and even sold her house to get money for her grandchildren, is shuttled among those very grandchildren--products of the "new" Russia--none of whom want her to stay with them since she's too much of a "burden" for them.
The USSR, 1946. The main character, Mikhail Krasnitsky, travels to different cities across the country. When he arrives, he commits cold-blooded murders, for reasons that are not yet evident. The Secret Service manages to connect all of these crimes and figure out that all of the victims were former death camp inmates. However, the murderer’s motive still remains unclear.
