A firm of solicitors do battle with the head of the local council over a parcel of river front land, owned by the Huggett family, in order to build a lido/community center.
Fortunately, the producers realised that the whole "Huggett" concept had run it's course, and so before they got just a bit too silly, retired the family with this rather fun poke at the British local government system. This time, it's "Ma" (Kathleen Harrison) who finds that a plot of land she, and cousin "Diana" (Diana Dors) inherited by the riverside is required by the council to build a leisure centre. Reluctant to sell, she soon discovers that the proponent of this plan is none-other than her husband (Jack Warner) who made the proposal blissfully unaware that his own family owned the land... When he decides to stand for office to facilitate the development, there are allegations of profiteering being bandied about and he has to think on his feet. It's light-hearted fun, this film - it swipes at the inefficiencies and red tape that always seems to manage to thwart even the most consensually popular of projects, and with a fittingly concluding number from daughter "Pet" (Petula Clark) the series signs off as it ran - amusingly, amiably and with most of it's self respect still intact.
