In a distant time of the past, Carl, a lone pachyrhinosaurus, ends up having his course collided with Bilbo, a small mammal. Together, they end up rescuing an orphaned baby dinosaur, with the aim of returning the baby to her herd, which has migrated to a new area. For that, they will still count on the questionable help of a predator, if they want to reach the child's herd in time. Think of it as an Ice Age spin-off of sorts.
