The Alps, the so called "Roof of Europe", stand for wild mountains, extreme lives, but also a magical world. This majestic mountain range connects eight countries and reaches heights of up to 4,000 metres above sea level. At a length of 1,200 kilometres, the Alps form both a connecting bridge between western and eastern Europe and a high barrier between southern and central Europe. The mountains act as a mighty water reservoir and continental watershed, feeding innumerable rivers that flow into three different big seas. Many peaks steeped in legend and history, such as the Matterhorn, the Grossglockner or the highest of them all, the Mount Blanc, tower above a sea of snow and ice-covered heights. Vast river valleys and huge forests cover giant areas, and craggy summits and rugged canyons dot the landscape. Despite extreme local weather conditions and the rapidly changing climatic circumstances at different times of the year, a diverse animal world was able to develop, which has adapted perfectly to its habitat. Eurasian lynx, griffon vulture, ibex and marmot are exposed to extreme seasonal fluctuations, from fleeting thunderstorms and landslides in summer to avalanches and frozen winter temperatures. The 2-part nature documentary provides insights into their lives in impressive images and shows the unbelievable variety of landscapes, flora and fauna that make the Alps a unique natural treasure in the heart of Europe.
