2006. In a quiet polar town, right on the seashore, the remains of an unknown person were found. Just at this time, senior police lieutenant Daniil Nekrasov and his wife Olga arrive in the city. The investigation reaches a dead end when the identity of the deceased is revealed. Anatoly Cherepanov, a simple worker from a gold mine, should not have been in the city. Someone smuggled him into the Arctic. Or is a cunning killer leading the investigation by the nose? Immersing himself in his work, Daniil ceases to understand where the real threat comes from. Work is closely intertwined with personal motives when he meets Alina, a former lover with whom he had to part due to past mistakes.
