Where Oxygen Fades follows an extraordinary scientific expedition to Aconcagua, the highest peak in the Americas. Driven by a deep passion for clinical research and a love for the mountains, a group of young Italian researchers undertakes a groundbreaking high-altitude mission to study life-threatening illnesses that strike above 3,000 meters.

Facing brutal winds, freezing temperatures, and the suffocating thin air above 6,000 meters, they climb without porters or guides, carrying on their backs not only their survival gear but also the weight of their scientific dreams. Along the way, they set up a temporary clinical research lab at altitudes where no such study had ever been conducted before.

This is more than an expedition: it's a mission fueled by curiosity, grit, and the quiet hope of doing good, even in a small way. With Italian food in their packs and science in their hearts, they push the boundaries of human endurance to better understand and help those who dare to venture where oxygen fades...
