The film primarily focuses on the experiences of a small group of soldiers as they venture into the desolate and inhospitable terrain of Afghanistan. They are led by a man named Wally Hamer, who possesses a deep knowledge of the region and its cultures.
As they progress through the treacherous landscape, the team begins to encounter strange occurrences and phenomena that they cannot explain. These range from mysterious voices on their radios to hallucinations and visions that make it difficult to distinguish reality from fiction.
As the situation becomes more dire, and the soldiers begin to suspect that they are not alone in the area, tensions within the group begin to escalate. In particular, the soldiers' relationships with the charismatic and seemingly omniscient Hamer become increasingly strained as they struggle to unravel the mysteries of the region.
Ultimately, the film builds to a climactic confrontation with a supernatural force that seems to have been lurking in the area for centuries. The soldiers are forced to confront their own limitations and fears as they battle this otherworldly enemy, raising questions about the nature of faith, war, and the human condition.
