After the idea of the prehistoric animal theme park proved to be a blatant failure, the dinosaurs stayed stuck on the island and rode the area in complete freedom, and the former park manager re-shaped himself as a lawyer to protect them. But these dinosaurs are now in great danger, and they risk to disappear as a species once it is discovered that a mighty volcano is about to erupt and destroy everything on the island, including dinosaurs. Claire tries to avoid a new extinction of prehistoric animals and joins with the former dinosaur trainer, Owen, to put together a rescue plan together.
