Like the "Dark Continent" of Africa, the dark island of Madagascar holds many chilling secrets. One of them is a long-thought extinct species of dinosaurs living at the country's core. A massive earthquake rocks the mountain range within the Andringitra National Park. The splitting earth reveals a network of tunnels, hidden away for millennia. Responding to the series of violent upheavals, a pack of hypersensitive predators flee their subterranean home; frenzied and hungry, they head for the surface. Former Navy SEAL Ian Hunt begrudgingly accepts an offer to lead an exploratory team. What they uncover is the find of a lifetime . . . if they survive long enough to tell anyone. Dinosaurs are alive and well at the heart of the dark island.
