In the heart of France at Château de Lalande, it's opening day for Stephanie and her beautifully restored chapel, but with rain pouring down, she'll need a Christmas miracle to keep spirits high. Over in the Loire Valley, Ben and Billie are serving up a Christmas Eve fish feast with plenty of festive sparkle at Château La Grande Maison. And in Brittany at Moulin du Couesnon, Donna and Paul are lighting up their grand old property and spreading Christmas cheer with hard hats, fairy lights and all!
