Almost 20 years after the start of the original "Brady Bunch" the kids are grown up and have kids of their own. Everyone is having a wonderful time back at the family house for Christmas, until Mike learns of a structural problem in one of the buildings he designed. As he is inspecting the problem, the building collapses, trapping him inside. As the whole family waits by the pile of rubble, they fear the worst. Will Dad be all right?

Jules has just inherited a quaint magical Christmas-themed village and Christmas tree farm bequeathed her by her grandmother. She plans to sell it and use the profits to buy her dream home in New York City. But the longer Jules stays on the farm and the more she learns how important Christmas Land has been to so many families, the more Jules starts to question her motives to sell.
