Of the 2,290 people who have climbed Mount Everest only 19 have made it via the notorious West Ridge. 21 have died trying. This brand new and exclusive five part documentary series captures the enthralling journey of a 21 person British Army team taking on one of the toughest mountaineering challenges in the world - to climb the treacherous West Ridge of Mount Everest. If they succeed, they will make mountaineering history, by becoming the first British climbers to do so, but to get there they will have to overcome a near-vertical kilometre of sheet ice, a knife-edge ridge, and winds of over 100mph, all at potentially lethal altitudes. Shot by the climbers themselves, as well as professional climbing cameramen, this documentary follows their progress every gruelling step of the way during their eight week expedition.
