Anthropological professor Conrad Hamilton attempts to study a new species of primate, possibly the missing link between humanity and the great ape, found in a hidden valley deep within the jungles of Thailand. Hamiltons initial research team tries to capture one of these new and very large primates, but fail and are all killed. Hamilton and his assistant Chenne, who survive because they are away from the camp site, scour the area looking for clues and remains of their team.Meanwhile, another research team is inbound, this one a crew of college anthropology students with no idea of what theyre in for. The students, Seth, Amy, Greg, Sydney, Josh, and Dani, are flown into a remote region of the Thai jungle, and picked up by a guide who drives them deeper into bush. He drops them off in a panic at the edge of trailroad, which leads further still into the foliage, claiming bad things are in there and wont go any further. He heads back the way he came, leaving the students to march forth into the unknown. They walk until they reach the end of trail and set up camp. As evening sets in, noises from the jungle raise suspicion until a set of glowing green eyes can be seen close by, watching. Just before the unknown creature attacks, Chenne arrives with a flare that scares off the unseen menace. ........
