Denise has always been the faithful wife and dutiful mother. As a matter of fact, it seems that is all she has been in the twenty-plus years she and her husband, Edward, have been married. But the kids are grown and out of the house, and she's ready to live a few dreams of her own. Edward, however, would like to keep things just the way they are, and Denise realizes that if she doesn't do something drastic, then all she will ever be is a mother and wife.

When Denise drops the bomb at Thanksgiving dinner that she is leaving Edward and selling the house, everyone is stunned, and her announcement opens the door to Morrison Family Dysfunction 101. Edward moves in with his crazy Aunt Etta, their daughter Christine moves back home when she suspects her husband is cheating on her, and their son Anthony is simply dazed and confused. In the midst of it all, Edward hatches a plan to get his wife back. Not only does he plan to be back at home and in their bed, but he also knows that, come Christmas, he and Denise will be...Rockin' Around That Christmas Tree.
