Summary Loose tethers on hiking trails, willfully destroyed signposts in the national park. Jonas suspects saboteurs at work who want to scare off the tourists and resort to drastic measures. Anticipating that the supposed conservationists have even more planned, he warns his team and the hiking groups to be particularly careful and attentive. In the meantime, entrepreneur Nollau has decided to focus entirely on tourism and to expand his old mountain tunnel with a climbing park. Jonas is skeptical about the plans because he doesn't trust Nollau, especially when he senses a deal. When the architect of the future climbing park falls while inspecting the rock due to a loose retaining iron and three young people flee, Jonas and Christoph give chase. Christoph can get a girl, but inexplicably lets her go. When Jonas confronts Christoph, he evades with an excuse. Maybe he's covering for someone? For Nollau it is obvious that Jonas is behind the accident to prevent his tourism plans, the conflict between the two flares up again. The situation escalates when the young conservationists riot in Nollau's mining museum and endanger the life of Jonas' nephew Lukas.
