In Pripyat, a former Soviet town in the exclusion zone around Chernobyl, a horribly mutilated body is found hanging from one of the buildings. Two men must find the culprit, though their motivations are very different. One is Commander Melnyk, a Ukrainian policeman with a strong sense of justice and duty. The other is Alexandre Rybalko, a Russian cop recruited by the victim’s father to find and execute the murderer. It soon becomes clear that this murder is linked to another crime committed in 1986, a double homicide that took place on the night the nuclear power plant exploded.
