The aim of the sport called "base-jumping" is to jump from a high position, that may be a mountain or can even be a building, and freefall for as long as possible before releasing the chute and glinding to the ground. Nic Feteris and Glenn Singleman clim the Trango Tower in Pakistan (6258 m) and achieve the world's highest base-jump. Their camera help us to experience their feelings during the flight. Glenn Singleman is a doctor, photographer and mountaineer who actively seeks adventure. His achievements include the first expedition to Mt Minto in the Antarctica, the famous dinner party in evening dress on Mount Huascaran, Peru's highest mountain, and the first hot air balloon flight over Everest. Nic Feteris is a real pioneer of this new sport and the film shows him in many spectacular situations.
