Santa's sleigh crashes and breaks in a snowstorm on Christmas Eve, and all of the presents are scattered across Adventure Bay. It's up to the PAW Patrol to fix the sleigh, round up the reindeer, find the presents, find the magic star, and most of all, save Christmas for Adventure Bay.

There's a mystery at Jake's mountain, and it's scaring away all the people who came to ski. The PAW Patrol must find out who or what left strange snow tracks. Could it be a Snow Monster? If they don't find what it is, they might have to close the slopes forever!
