Vertige (2009), also known by its English title High Lane, is a French survival horror film that combines physical danger with psychological tension. The story follows a group of young friends who decide to go on a climbing trip in the mountains to honor the memory of a deceased companion. What begins as an adventurous and emotional journey soon turns into a terrifying struggle for survival in an isolated and hostile environment.

The group chooses an abandoned via ferrata, a climbing route equipped with cables and ladders fixed to a cliff. From the start, the setting creates a sense of unease, as warning signs suggest that the path is unsafe. Despite this, the characters continue, driven by curiosity and confidence. The vast mountains, steep cliffs, and narrow paths emphasize how small and vulnerable the group is compared to nature.

As the climb progresses, accidents begin to happen, and tension grows among the friends. Their fear is not only caused by the dangerous terrain but also by the feeling that they are being watched. Soon, they realize that they are not alone on the mountain. A mysterious figure starts hunting them one by one, turning the trip into a deadly game. At this point, the film shifts from an adventure story into a brutal survival horror.

One of the film’s strengths is how it uses height and vertigo as a source of fear. The camera often focuses on the depth below the characters, making the audience feel dizzy and anxious. Falling becomes a constant threat, and even simple movements can lead to death. This fear of heights is combined with violence, creating an intense and uncomfortable atmosphere.

The characters are forced to confront not only the killer but also their own weaknesses. Trust begins to break down, and panic leads to poor decisions. The mountain, once a place of freedom and challenge, becomes a prison with no easy escape. Each death increases the sense of hopelessness and isolation.

In the end, Vertige is more than just a slasher film. It explores how humans react when pushed to their limits, both physically and mentally. Through its realistic setting and relentless tension, the film leaves a strong impression and reminds viewers of the thin line between adventure and disaster.
