Meteorologist Hannes (Sepp Rist) works alone at a remote weather station below the summit of Mont Blanc in the French Alps. Every day he gathers data on weather conditions. When the weather is clear, he is able to use his telescope to gaze down at the town of Chamonix in the valley far below. His solitary life is interrupted only by the daily weather reports he transmits via Morse code to various weather centres throughout Europe. He is also able to listen to his friend Walter perform his organ concerts on the radio.
