Thrilled with her flying experience over Mont Blanc, Hella persuades her father to join her on another flight to the weather station to visit Hannes—an old friend of her father (Friedrich Kayßler) who once worked at that station. At the small remote station, Hella is fascinated by the scientific equipment—and with Hannes. The next morning, Hannes takes Hella with him to the summit of Mont Blanc to capture that day's climate conditions. While they are away, Hella's father goes out to study the geology and falls from a rocky ledge and is killed. The young meteorologist and his female companion witness the fatal accident.
