The disastrous meltdown of a nuclear power plant in Northern Spain created a contaminated no-go zone and left the nearby provincial city and inhabitants in a state of shock and mourning. Three years later, while the city prepares for the commemoration ceremony, a mutilated body is found in a warehouse. Police inspector Hector Uria's search for the murderer takes him deep into the no-go zone and into his own past.
