Meet Speckles. He's a Tarbosaurus, and lives a happy life in his forest home with his mom and siblings. Until one day, as he's just learning to hunt, he encounters One-Eye, a Tyrannosaur looking for a new place to live. His herd is attacked, leaving poor Speckles alone in the world. But when he meets Blue Eyes, another lonely and lost Tarbosaur, they become close companions - and then, over time, a family of their own.
