As a forestry student, Anja Grimm (Henriette Confurius) finds herself in the remote area of the Upper Palatinate Forest where she spent her holidays with her parents as an eight-year-old girl and where her father disappeared without a trace. Shortly after their arrival, a brutal murder takes place. Anja's suspicion that the perpetrator knows something about her father's fate soon arouses suspicion and hostility not only among the villagers. Even the police react extremely reservedly to her investigations.
