[N 1]Meteorologist Hannes (Sepp Rist) works alone at a remote weather station below the summit of Mont Blanc in the French Alps.

At the Chamonix observatory down in the valley, an astronomer's daughter, Hella Armstrong (Leni Riefenstahl), gazes up at the night sky, helping her father with his work.

As they approach Hannes' weather station, she drops a small evergreen tree down by parachute with a note introducing herself.

Before she leaves with the team that arrived to bring her father's body back down to the valley, Hannes asks her to look up his good friend Walter Petersen (Mathias Wieman).

But when he receives a letter from Walter informing him of his intended engagement to Hella, who knows nothing of the matter, he is so shocked by the news that he decides to stay at the weather station for another season and sends the replacement team back home.

He then attempts to make his way down the mountain, but the storm is too severe, and the snow bridges over the deep gorges have collapsed, cutting off the path.

Exhausted and with hope nearly gone, he makes his way back to the storm damaged station and manages to send out an emergency SOS signal.

Filmed on location in Arosa, Switzerland, Babelsberg Observatory in Potsdam, Germany, and Mont-Blanc in Chamonix, France, Stürme über dem Mont Blanc is notable for its dramatic mountain footage and depictions of a violent snow storm.
