Because she is marrying the man who assumed the mantle of Santa Claus last December 26, Beth's postponed wedding has to be rescheduled for Xmas eve. Overwhelmed by selling the house she and her son share and the prospect of the duties of Mrs. Claus, she has to call on her estranged socialite Grinch of a mother to arrange the wedding. Of course her mom has never met the fiancé nor his family and has no inkling of his secret. This is a sequel to 2004's Single Santa Seeks Mrs. Claus.
