An unidentified body is found in the remains of a trailer after a fire 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 local so-called neighbourhood watch played? Police supervisor Klas Freden decides to go over Martin Beck's head and recruit charismatic Norwegian homicide investigator, Steinar Hovland. The newly-structured Beck group face a power struggle, and Martin struggles to find his way back to his old self.
