"Perilous Assignment" is an episode of ABC's Walt Disney Presents. Disney loved to show viewers behind the scenes of the daring shoots of its theatrically released or TV shows. The theme of the episode is the making of his next film, The Third Man on the Mountain, an adaptation of James Ramsey Ullman's novel Banner in the Sky, based on the true story of the first ascent of the Matterhorn. Walt Disney will not be limited to a simple promotional making-of. He offers to meet exceptional people, including the French mountain guide Gaston Rébuffat. The latter will show climbing techniques and then reveal breathtaking images of his ascents of steep cliffs with a client for the ascent of Mont-Blanc, filmed for the occasion. In 1958, Walt Disney will therefore offer him to be deputy director on the high mountain scenes of the film "The Third Man on the Mountain".

Glacier pilot Hermann Geiger flies over a four-thousand-meter peak in the Valais Alps and observes a glacier collapse. The next day, three rope teams climb through this glacier to Dent Blanche. However, Dr. Gruber, accompanied by his wife, a young engineer named Gisler with his girlfriend Monica, two young men named Charly and Roby, mountain guide Perren, and the athletic Englishman Puckle get caught in a storm. Due to the weather conditions, Gruber slips and drags the other participants down with him. His wife, who had stayed behind in a hut, alerts the mountain rescue service. The storm initially prevents glacier pilot Geiger from taking action, but he then risks a breakneck landing to rescue the group.
