Hark! the Gerrard angels sing...

It's Christmas Eve, and the Gerrard brothers mean to make the most of it. They've taken their wives, their children, and their three delightful sisters, and removed to the most wintery estate they have to set the scene. Determined to give their families the most perfect Christmas they've ever known, they go to unmatched extremes in their efforts, planning out every detail.

But there are surprises in store for all of them this Christmas season, some of which Colin and Kit just can't believe. It's a house filled with Gerrards of all ages, brimming with holly and ivy, all the festiveness of the holiday season, and much more. What could possibly go wrong?
