Overview: Extreme habitats such as the karst landscapes of the Steinernes Meer, the Watzmann with the highest rock face in the Eastern Alps, the Wimbachgries with its constantly shifting streams of debris and the Königssee, one of the deepest lakes in Germany, belong to the Berchtesgaden National Park. If you want to survive in this wilderness, you have to be perfectly adapted to your environment. The documentary introduces some of the most interesting mountain people. At dizzying heights there are chamois with their newborn fawns, always on the lookout for the claws of the golden eagle, and camouflage artists such as the ptarmigan and mountain flowers such as the legendary edelweiss. Marmots tussle on the high pastures, and in the depths of the Königssee the burbot spawns - originally a sea fish that ended up in fresh water ten million years ago.
