Maggie and Jeff have remained friends after the divorce and continued to celebrate Christmas together with the children. Now, however, Jeff has met a new girl, Kate, and wants to take the kids to her parents' place in Aspen. When Kate realizes that Maggie will be alone for Christmas, she invites her too and the children persuade her to come along. However, friction arises when Kate is popular with the children and Maggie's Christmas traditions are overshadowed. However, Sam, Kate's brother, sees this and takes Maggie's side.
A good story about new constellations and the problems that arise with it. (Not exactly very deep, but it is a romantic movie after all).
