Luckily for young Arlo, his parents and his two siblings, the mighty dinosaurs were not wiped out 65 million years ago. When a rainstorm washes poor Arlo downriver, he ends up bruised, battered and miles away from home. Good fortune shines on the frightened dino when he meets Spot, a Neanderthal boy who offers his help and friendship. Together, the unlikely duo embark on an epic adventure to reunite Arlo with his beloved family.
