For the first time in their lives, five amputees from ages 19 to 64 -Jérôme, Sarah, Christophe, Luca and Michel - will climb a 3000m peak in the Alps. Physically prepared or not, they know that their willpower will be stronger than the pain: they are determined to prove that all amputees can walk, run and hike on their own two feet again, thanks to a project of affordable prosthetic blades developed by young engineers.
