After years of living away from their families, Pete and Nikki have moved back down south to Kent with the dream of restoring a derelict windmill that's been owned by Pete's family for over 100 years. Locally listed, the windmill has been a roofless ruin since 1915, and its tapering structure overlooks an area of outstanding natural beauty in the heart of the county. The build nearly comes unstuck when Nikki, who had recovered from cancer, suddenly becomes unwell again. George is on hand to advise, and support them on their restoration journey as they battle with Nikki's illness.
