Trailer for the documentary The Ridge.
The south wall of Mount Annapurna in the Nepalese Himalayas is known among climbers as the most dangerous climb in the world. To reach the mountain's summit at over 8,000 meters above sea level, mountaineers have to traverse a seven-kilometer-long ridge at 7,500 meters - an impossible task, especially for "pure" climbers who brave the thin air without oxygen tanks. So when experienced Spanish climber Iñaki Ochoa de Olza falls seriously ill while crossing the ridge in 2008, his hopes are slim. After his climbing partner Horia Colibasanu sounds the alarm, 12 fellow climbers from all over the world mount a highly dangerous rescue operation.
