A man disappears without a trace in the mountains. Andrea Stamm last saw him after she fulfilled his final wish to accompany him to the mountain. It could become tricky for the mountain guide if the association carries out its threat to exclude her. Andrea sets out on a search - without success. She encounters the lonely boy Magnus, who roams the mountains and dreams of the sea. She also receives support from Dr. Daniel Meyer, who is also on a quest for clues. He no longer finds the "good old days" in the mountain village, but rather a corrupt municipal administrator and mobile phone antennas in the bell tower. Do they really make people sick, as Anita, the cancer-stricken innkeeper and artist, claims? Daniel Meyer searches for explanations for the inexplicable - and for his great love. After "Die Wand der Sila" and "Steinschlag," "Spurlos" is the third part.
