There is a thin line between life and death. Ski mountaineers Hilaree Nelson and Jim Morrison have often experienced this firsthand. Despite this, they're thinking about pursuing another summit, the 8516-meter-high Lhotse, and the descent of their lives. Never before has it been possible to ski the eight-thousand-meter Lhotse Couloir, 50-degree slope and an absolute dream line. There is very little snow on some aspects of the Lhotse and the weather has to cooperate, so these two Americans don't have much time. They must set out to fulfil their dream at high speed and with minimal equipment.
