Billy and Gwendoline have their hands full: they rope in Dick to help them put up a chandelier then have to track down some wild boars that are causing chaos in and around the chateau. Clive and Tanith attempt to make a fully self-sufficient dish for their hotel's restaurant then test it out. And at Paul and Karen's chateau, Paul continues the task of converting their water tower into an office, no mean feat in 33 degree heat.

In the Picardy region, Tim and Margreeth, who run their chateau as a B&B, plan to sell 'gite timeshares' and build an upmarket caravan park to grow the business. But first Tim needs to evict a swarm of bees. Near Calais, Nicole and Stephan need income to turn their chateau into a B&B, so they're converting their hall into a tearoom. Alison and Paul have spent nine years renovating their ancient chateau. To give up their professional day jobs, they must increase bookings - so they're creating a 'wedding terrace' around the pool, with an outside kitchen. But there's a leak in the pool and Paul gets distracted by an old motorcycle.
