Polina works at the dry cleaners. She has a son, Vitya, and a husband, Aleksandr. Polina's life was no different from the lives of others, until grief happened in her family. The Rottweiler of Muravyov's rich neighbor mutilated Polina's son, ten-year-old Vitya. The court sentenced Muravyov to a small fine. And a week later, as if nothing had happened, he went out for a walk with a dangerous dog near the playground again. And when Aleksandr made a remark to him, he almost set his dog on the man.
