At Janet and Philip's chateau, they try to complete their hallway transformation before their Christmas extravaganza. It's also all hands on deck at Chateau de Dohem for Wendy and Marcus, as they prepare for their first-ever Christmas-themed murder mystery party. At Chateau de Lalacelle, Terry and Ashley make their own snow indoors by bringing down one of the chateau ceilings, before they can switch on their 5000 lights to start Christmas properly.
