It's Christmas with the Chandlers but no one seems to have the Christmas spirit - except for Stephanie, that is. Marci and Blair are obsessing over being the perfect parents, Myra and Donald have retired and suddenly feel useless and Elizabeth is bending over backwards to get a promotion at work. Add to that Stephanie's blooming romance with Lawrence - who is torn between being with her and continuing his mission work - and Christmas seems to be taking a back seat. That is, until a group of kids at an orphanage helps the family to realize that there's more to Christmas than wrapping gifts and baking cookies.
