In spring 2009, Spanish mountaineer Edurne Pasaban and the film crew of television programme Al filo de lo imposible attempted to climb Kangchenjunga, the world’s third highest peak and one of the most arduous on account of the enormous 7500-metre climbing distance. This was Pasaban’s twelfth successful climb of an Eight Thousander and a step closer to her goal of becoming the first woman to climb the fourteen highest mountains in the world. The film follows the exploits of Pasaban and her climbing partners Juan Oiarzabal, Ferrán Latorre, Alex Chicon, Jorge Egocheaga and Asier Izaguirre.
