More than 100 years on from the tragic events of the 1924 Mount Everest Expedition, Julie Summers, the great niece of Sandy Irvine, and mountaineer and narrator Matt Sharman seek insights into the 1920s Everest expeditions. Along with extensive historical footage, photographs and documents, as well as interviews with Everest scholars and mountaineers, the pair don't just re-tell the story of the three Everest expeditions of the 1920s, but re-examine them, asking what the mountain means for climbers and the people of Nepal 100 years on from the infamous disappearance of Mallory and Irvine.
