Four-year-old Diana Clarke sends her wish to Santa Claus, but lost in the lining of a sack, it isn't discovered for thirty years. Now, Santa has a problem. No child's wish has ever gone unanswered, but the child isn't a child anymore.Believing there is nothing in Santa's Village to satisfy the little girl's wish now that she's an adult, he calls on a Higher Power and is given a suggestion. Although most of Santa's workshops contain only toys for boys and girls, there is one that holds a possible solution to his problem. Learning that Diana will be attending three upcoming Christmas parties, Santa calls on his lead elf to deliver three sprigs of mistletoe, hoping that under one, Diana Clarke will find what she asked for thirty years before.
