S1, E3: The weather improves enough for the team to get back on the mountain. As they push up towards camp 3, at 7,200 metres, a Sherpa rebellion halts their progress.The super strong Nepalese Sherpas they have employed to help carry their kit feel they are not getting enough rest, and all head down the mountain. Undaunted, the army carry on up the mountain, but then the expedition is hit by a tragedy.
