There are few places left to discover and a few adventures yet to be done. Climbing Mount Everest in winter, with no supplemental oxygen and a light expedition, is like a space trip. During winter season, it has only been climbed once in history, it was a Polish expedition in 1980 but they used supplementary oxygen to achieve it. Since then, no one has ever treaded the world's highest mountain in winter and no one has ever achieved it without artificial oxygen.
Alex can do it: he has the necessary drive, experience (expert in winter expeditions to the Himalayas), strength, joy (never to be discouraged) and a point of madness, a much needed quality common to all adventurist. In addition, he has teamed up with Carlos, a young promise with no experience in the Himalayas but with an immense capacity to convey the essence of the brutal adventure.
