As Jonathan and Michael prepare their chateau for the big wedding, they have a sewage problem that threatens to take the whole first floor out of action; with 40 guests due, the timing couldn't be worse. Mandy and Steve continue to have pool problems, and, with the first guests of the season about to arrive, they also have to contend with a collapsed wall. It's decision time for Philip and Angelina: can they find their own chateau to buy? Or is it time to return to Britain? And Dick and Angel go hunting in their own chateau's attic for goodies and treasures left over by the previous owners - and are amazed by what they discover.

Dick's with Donna McDougal who believes a horde of ancient armour was hidden in her chateau's lake. Will they be able to locate the mythical horde? In the Dordogne, we meet new parents Tim and Krys. The young couple are struggling to juggle their new baby with converting an attic into a bed and breakfast suite to generate much-needed extra cash. And in their chateau near Limoges, chef Colette and front-of-house husband Paul try to launch an ambitious new menu to bring in more customers and revenue.
