Mount Meru stands as a silent monolith that challenges climbers from all over the world. Directors Elizabeth Chai Vasarhelyi and Jimmy Chin capture the obsessiveness and epic struggles of three elite climbers (one of whom happens to be Chin) attempting to scale what is considered to be the most complicated and dangerous peak in the Himalayas, which up until then had never been completely scaled. Regular non-climbers will likely never understand what compels individuals to embark on such adventures, but Meru dares to draw us inside their heads and carry us up the mountain with them.
