Blott on the Landscape (1985)

Conservative MP Sir Giles Lynchwood schemes to have a government-backed motorway run through his wife's ancestral estate (Handyman Hall) to cash in on compensation money. However, his independent-minded wife, Lady Maud, teams up with their mysterious and resourceful handyman, Blott, to thwart the plans through sabotage, blackmail, and outright anarchy.
