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 comes to a standstill when the identity of the deceased is revealed. Anatoly Cherepanov - a simple hard worker from a gold mine - should not have been in the city. Someone secretly drove him to the Arctic. Or does the cunning killer lead the investigation by the nose? Plunging headlong into work, Daniel ceases to understand where the real threat comes from. The work is closely intertwined with personal motives when he meets with Alina, a former lover with whom he had to part due to the mistakes of the past.
