A group of experienced mountaineers embark on an adventurous hiking trip through the remote Scottish Highlands. While navigating through the rugged terrain, they inadvertently stumble upon a young Serbian girl buried alive in a small chamber. Facing an immediate and life-threatening situation, they rescue the girl but quickly realize that their discovery is not a coincidence. The girl had been kidnapped and hidden away by dangerous criminals who will stop at nothing to retrieve her.

With their lives now in unprecedented peril, the mountaineers must maneuver through the treacherous wilderness, evading their relentless pursuers. As the group's unity and survival skills are put to the test, they uncover deeper layers of deceit and treachery. The mountains, instead of providing isolation and beauty, become a hostile battlefield where trust is scarce and the stakes are lethally high. As they face increasingly desperate measures to stay alive, an all-encompassing game of cat and mouse ensues, leaving them to confront whether their bond can withstand the escalating violence.
