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.

Dick's at home building a compost toilet for guests to use at outside weddings. Also in the Pays de la Loire, twenty-something couple Billy and Gwendoline want to open their chateau as a wedding location, but it's not going to plan as the chimney appears to have caught fire. Near Dijon, Clive and Tanith run an upmarket chateau hotel but need to win over the locals, so they put on an open day. And sisters Tanya and Marian prepare to visit their chateau in the Loire Valley. They need to get it ready for the first guests of the summer in less than a week's time but are faced with everything from dead flies to leaking swimming pools.
