This stunningly shot and nail-bitingly suspenseful documentary follows Phurba Tashi Sherpa as he undertakes his world-record-setting 22nd ascent of Mount Everest.

Director Jennifer Peedom set out to uncover tension in the 2014 Everest climbing season from the Sherpas' point of view, and instead captured a tragedy when an avalanche struck, killing 16 Sherpas. Sherpa tells the story of how the Sherpas united after the tragedy in the face of fierce opposition to reclaim the mountain they call Chomolungma.
