When winter tightens its grip on the North Pole, freezing the elves' workshop and halting their toy-making, Santa sends a brave elf and a loyal reindeer on a quest to restore the gentle cold of Christmas. On their arduous journey, they traverse towering snowy peaks, windswept candy cane-filled valleys, and raging blizzards, discovering that even the coldest winter can be softened by kindness, friendship, and the Christmas spirit.
