Private detective Josef Matula investigates again. More bad than right, he hits in Frankfurt as a department store detective until it leads him to a new order to the North Sea coast.
Private detective Josef Matula is with his usual companion, the dog Dr. med. Renz, on the way to Italy, when his rickety minibus engine fails. During his subsequent unplanned stay in a small mountain village he discovers the body of a mountaineer while hiking. He begins to investigate the death and by the look of it, it could be either accident, suicide or even a murder. However, the conspiratorial community is not very enthusiastic about his investigations and when he comes close to solving the case, his own life is in danger too.
