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.
