When the entire Montgomery family comes together, it makes for a holiday to remember. But it's more than just the tree, decorations, and gifts that have everyone talking. With so many people crammed under one roof, there's bound to be some drama. Between last-minute business crises, talks of retirement, a new relationship, a sprinkle of marital problems, lots of snow, and a surprise baby, this has all the makings of a blue Christmas. They'll need more than one Christmas miracle to get everything back on track, and hopefully Santa–or William Montgomery–will come to the rescue. One thing's for sure, it's a Christmas they'll be talking about for years to come.
