Mary Class is a highly successful business executive - who just happens to be the daughter of Santa Claus. But when her father falls ill, Mary returns to the North Pole and the life she left behind to take over for her dad and implement her innovative ideas for running Christmas.

Santa's in the midst of a late-life crisis -- he's tired of the responsibilities of the job and is ready to pass on the reins to Mary, who feels torn between the family business and running her own high stakes firm in New York City, along with balancing a relationship with the love of her life, Luke (Dean McDermott). The situation gets increasingly dire when Teri, an ambitious new arrival to the North Pole, sows dissension at the workshop in an effort to take over Christmas.
