Vietnam. 1968. A search and rescue team known as Vulture Squad is sent to an isolated jungle valley to uncover the fate of a missing Green Beret platoon. As they hunt through the primordial depths of the valley and the casualties mount, the men of Vulture Squad must abandon their human nature and give in to their savage instincts in order to survive the horrors they face.

In between revising the script and meeting with actors, Sparke said, “Dinosaurs in the Vietnam war? What’s not to love about that concept?! When I first heard about the books, I loved the ideas and concepts Ethan brought into them, and we’re shaping our film version into an exciting survival-horror film.”
