Pod – a pyroraptor – finds himself alone in the world after his sisters die in a tidal wave that also sweeps him out to sea. After landing on an island populated by dwarf-sized dinosaurs, Pod discovers that he's become the apex predator. But, as a gregarious and social pack animal, Pod learns that it's lonely at the top of the food chain.
As a young male of a Daspletosaurus pack, it's Das' job to herd unsuspecting prey towards his fellow hunters. But he's easily distracted and ruins several hunts – getting him in deep trouble with his mother, the pack leader. When a distant volcano threatens eruption, the dinosaurs are caught in a dangerous spot – unless Das can lead them to safety.
