Narrated by John Simm, this 90-minute observational programme follows the quintet from training in the UK with Harry to their attempt to climb the 8,848-metre peak. In a year that saw 11 deaths on the world's highest mountain, the team struggles with altitude, night climbs in extreme temperatures, deadly avalanches and terrifying crossings over seemingly bottomless crevasses. It is a journey almost as fraught and as tough as the one these wounded soldiers have taken since being blown up, shot and set on fire. / This film also tells the human story of the journey the soldiers have been on since being wounded - Private Jaco van Gass lost his left arm in a rocket-propelled grenade attack in 2009; Private Karl Hinett suffered 37 per cent burns in a petrol bomb attack on his tank in Basra; Captain Martin Hewitt and Captain David Wiseman were both shot through the chest in Afghanistan; and Doctor Francis Atkinson was ambushed and shot in 2011, ending his chances of becoming a surgeon.
