Alla devoted most of her life to her ex-husbands, son and daughter. She works as a tutor while continuing to support her adult children and husbands. Relatives come to her for lunch every day, not at all interested in Alla herself. In one of these family dinners, choking on potatoes, Alla almost dies, but "relatives" do not even notice this.
1984, a small town near Vitebsk. Criminals who have robbed a local store are hiding from the scene in a truck. A traffic police car is chasing them. Soon the company car disappears. The search for the criminals and the traffic police officer begins, but instead of them, the corpse of a girl is found in the forest. The case is entrusted to local police officer Mikhail Shakhnovich, and a specialist from Minsk, Leonid Ipatiev, is sent to help him. He quickly realizes that Vitebsk colleagues are not particularly zealous in their work: the system is based on bribes and fabricated cases. And while Shakhnovich arrests the first ones who come across, the bodies of women continue to be found in the region.
