Watch LookMovie. In July 2024, Liv Sansoz and Bertrand Roche (aka Zébulon) made history in Himalayan mountaineering by climbing K2 (8,611m) without supplemental oxygen, then paragliding from the summit. The couple achieved a highly coveted first, and for Zébulon, the feat was all the more impressive as he had already completed the first tandem paragliding flight from Everest in 2001. More than just a climb, this film is a love story where Liv and Zeb share their doubts, emotions, and determination, carrying a shared dream where every step is taken together, united to the very end.
