Everest Without Oxygen

More than 5,000 climbers have reached the summit of Everest, but just over 200 have done so without bringing oxygen and many have died in the experiment. Rasmus dreams of becoming the first Dane to reach the highest limit of the world without an oxygen bottle on his back, but the pursuit of the dream is bone-chilling and ends up as an obsession. It takes 4 years of his life, many opt-outs and the relationship with his girlfriend is put to the test, while he sees friends risking their lives, and lose it, on the mythical mountain.
