The follow-up to Discovery Channel’s successful six-part docuseries about scaling Mount Everest features the oldest climber ever to make it to the summit: 71-year-old Katsusuke Yanagisawa. Using high-altitude, high-resolution cameras operated by sherpas, the series follows a new group of climbers on its trek up, talking to them about their fears, concerns and motivations. With the danger of frostbite and oxygen depravation, when the climbers encounter other groups going up, things can get pretty hairy.
