An unidentified body is found in the remains left after a fire in a trailer at a run-down caravan park. The owner of the trailer, a young drug-addicted woman, is missing, but is she really the victim? And what role has the so-called neighbourhood watch from the nearby community played? The case is difficult to solve, with everyone involved guarding their secrets, regardless of social class. Furthermore, police supervisor Klas FredÃ©n decides to go over Martin Beckâs head and recruit charismatic, Norwegian homicide investigator, Steinar Hovland. The newly-structured Beck group faces the blight of a power struggle. And Martin struggles to find his way back to his old self.
