Former teacher Anatoly Isakov is forced to leave his main profession and become an illegal taxi driver, the so-called “bombi”, working “under the black flag” in order to feed his family: a small two-year-old son and a pregnant wife. His retired mother helps her son as much as she can, but this, of course, is not enough for the young family. Just before the onset of the new year 2013, Anatoly’s mother unexpectedly dies in a traffic accident, and little Artem, Anatoly’s son, who was with her at the time, miraculously survives alive The driver is fleeing the scene. Investigative authorities manage to find the car that was used in the hit-and-run, but its owner turns out to be a well-known leader of an organized crime group in the city, who covers up his criminal activities with official business. This “authority” also has great connections. The bandit states that his car was stolen a few hours before the accident. The justice authorities fail to prove the involvement of the car owner in the collision, and Isakov decides to launch his own investigation in order to restore justice and punishment.
