The remarkable dinosaurs that lived under the Northern Lights had to make a choice, brave the winter or head south to find the sun.　　Join Scar, a young Edmontosaurus embarking on his first thousand-mile migration. It is a journey for survival that is fraught with danger; blizzards, volcanic eruptions and deadly predators lie ahead. Meanwhile Patch, a juvenile Troodon, left alone in the North, must learn to survive in one of the harshest environments the Earth has ever known.　　This epic feature-length adventure portrays an incredible polar odyssey that actually happened but has never　　been witnessed before.

Featuring stunning animation and a painstakingly recreated digital world, it can truly be said that the dinosaur film has evolved.
