Based on true events, Tenzing chronicles the little-known story of Tenzing Norgay (Genden Phuntsok), a gifted Himalayan climber who, alongside New Zealand mountaineer Edmund Hillary (Tom Hiddleston), became the first to summit Mount Everest. Encouraged by his wife Dawa (Thinley Lhamo), Tenzing finds an ally in expedition secretary Jill Henderson (Caitríona Balfe). Together, they persuade Colonel John Hunt (Willem Dafoe) that Tenzing belongs on the British climbing team, rather than merely serving it. Where Western climbers see “Everest” as something to be conquered, Tenzing reveres “Chomolungma” as the sacred mother goddess. What follows is an ascent defined as much by the tensions between backgrounds, classes and competing ambitions as by the perils of the mountain itself.
