Watch on SFlix. This entertaining film documents the first ascent of the very difficult South Face of Annapurna, a huge Himalayan wall that the right team could achieve the seemingly impossible. The ascent of the South Face of Annapurna in 1970 was one of those breakthrough ascents - both technically and psychologically. Chris Bonington assembled the cream of British mountaineering and American Tom Frost for the attempt. The documentary is punctuated by wry observation, understatement and cutting humor from a by-gone age when the game of taking huge risks was matched by a determination not to take it too seriously.
