As a passion project, this film follows French highliner Julien Roux - a bold athlete paradoxically driven by a fear of heights. Shot in his hometown of Annecy, it offers an intimate look at his daily routines and mental battles, capturing what fuels his pursuit of ever greater challenges.

Two years later, that journey led to a world record: the highest highline ever walked between two hot air balloons at 5,000 meters. Suspended in the sky, Julien confronted both gravity and fear, proving that true courage lies not in being fearless, but in facing fear head-on.
