Elite ski mountaineers and life partners Jim Morrison and Hilaree Nelson set their sights on an unprecedented feat: climbing and skiing the direct North Face of Mount Everest, one of the mountain's most dangerous routes and a line no one has successfully skied before. Filmed by longtime friends and collaborators Elizabeth Chai Vasarhelyi and Jimmy Chin, the documentary becomes an intimate portrait of love, obsession and the pursuit of the impossible, following the couple's dream through tragedy and its long, difficult aftermath. A visually breathtaking if tonally difficult extreme-sports documentary that struggles to fully reconcile its subjects' driven self-involvement with the very real grief at its centre.
