Leni Riefenstahl made her film debut in this "mountain film" by writer/director Arnold Fanck, and went on to appear in five more under his direction. In she plays the professional dancer Diotima who finds herself the apex of a love triangle when she is pursued by two mountain climbers, Vigo (Ernst Petersen) and his unnamed older friend (Luis Trenker). Diotima is drawn to the elder climber but can't refrain from encouraging Vigo's attentions as well in a spirited skiing session. She has a moment of intimacy with Vigo, and when the friend sees them together he angrily challenges Vigo to a dangerous climbing tour. During the trek he causes Vigo to fall but repents and rescues him. Both men, however, soon become lost in the mountains, and they perish before Diotima and the rescue team can reach them.
