A found footage film opens with the discovery of a collection of unexplainable video recordings from a lost expedition in the jungles of South America. A group of U.S. military personnel and scientists are dispatched on a mission to investigate the mysterious circumstances surrounding the disappearance of the previous team. Among them are a journalist and his cameraman, who have been given exclusive permission to document the high-stakes endeavor. As they trek through the dense foliage and treacherous terrain, they uncover something that suggests the existence of an unknown creature or alien life form.

The tension mounts as the team progresses deeper into the jungle, encountering increasingly strange and unsettling phenomena. They find themselves facing not only the natural dangers inherent to the wild environment but also an increasingly palpable sense of dread linked to their otherworldly discoveries. Skepticism turns to fear as the evidence builds, pointing to a series of events that challenge their understanding of biology and physics, propelling them towards a revelation that could change humanity's view of its place in the universe. With each step forward, the team's survival becomes more precarious, pushing them to their physical and mental limits as they strive to unravel the enigma and record their findings for the world.
