The polar city of Bright is cut off from the mainland, and you can only get to it by winter road, accessible from November to May. Once the city flourished, people from all over the Union came here to work, but now there are only blocks of abandoned houses and a vague future. The remaining residents live side by side with the indigenous population, who live separately. The development of an old mine, where hundreds of marginal workers with dubious backgrounds have arrived, can revive this dead landscape. When the city is rocked by the brutal murder of a young woman, Dmitry Tikhomirov, the head of the local Department of Internal Affairs, worries too much that publicity may infringe on the interests of the construction site. But his daughter-in-law Zoya does not let him let the matter go. At one time, she rejected her ancestral vocation, married Dmitry's son and joined the police, for which she was cursed by her mother. Three years ago, she lost her husband and eldest child in an accident, and now she has only her youngest son, Artyom and Dmitry. Zoya is ready to do anything for their well-being, and when investigator Pyotr Gorelov, her former lover, is sent to Moscow to help, she is ready to withstand this ordeal. The elusive serial killer "Hunter" begins a deadly game with the investigation, and in order to get out of it unscathed, Zoya must return to what she has long denied herself — a natural gift.
