After some quick thinking, he leaves a gift on her pillow – the only thing left on his sleigh – because, after all, every good child deserves a Christmas present, right? As he heads for the North Pole with his tired and trusty reindeers, he hopes Valerie will understand it's the thought that counts.

Now a miserly millionaire, Valerie sits at the helm of the Ainsworth dynasty, hell-bent on making Santa pay for forgetting her that Christmas.

Her nephew Wolly and his grandpa Joe are about to embark on their biggest adventure yet as they join forces with Santa.
