When young Chris Moose is forced to leave his homeland behind, he begins a long and dangerous journey to the northlands, in search of a secret network rumoured to spread happiness around the world.
Along the way, he meets a family of orangutans on the move, the crocodiles who run the river crossing, Sophie the Snail and the Lightning Crow.
Arriving in the northlands, reindeer Vix introduces him to her team, who work on a secret annual mission. But not everyone is willing to accept Chris Moose - some of the other reindeer don’t like the thought that he might bring change.
When a catastrophe threatens to put the team out of action, Chris and the reindeer must learn to put their differences aside and let their strengths combine if they are to save Christmas.
For the first time in history, a moose will help pull the famous sleigh!
