Vertige (2009)

Trailer:
A group of thrill-seeking friends—Fred, Chloé, Loïc, Karine, and Guillaume—set off on an adventurous hiking trip in the remote mountains of Eastern Europe.
Eager to rekindle their old bond, they decide to take a shortcut along a long-abandoned via ferrata—a dangerous climbing route suspended high above the ground. At first, the adrenaline rush is exhilarating, but as they ascend, their excitement turns to dread when they realize the path is far from stable. Rusty cables snap, crumbling ledges give way, and the mountain itself seems determined to claim them.
But the real nightmare is just beginning. When one of them falls to their death in a tragic accident, the group is left stranded, battling not only the treacherous heights but something far worse. They soon discover that they are not alone—someone, or something, is stalking them from the shadows. Their supposed accident may not have been an accident at all. As paranoia sets in, the remaining friends are forced into a desperate fight for survival, trying to escape both the deadly cliffs and the unseen predator lurking in the wilderness.
Vertige is a gripping blend of survival horror and psychological terror, turning the beauty of nature into a death trap. With breathtaking cinematography, relentless tension, and a chilling descent into madness, the film keeps audiences on edge, questioning whether the biggest threat lies in the towering cliffs—or within the minds of those who dare to climb them.
