While Georgie goes into hiding, Lucia, Queen of Tilling, approaches her fiftieth birthday, determined to make her mark on history.
With Mapp and Lucia running against each other in the council elections, loyalties are divided and a new baby is expected in Tilling.
As the Mapp-Flints fall on hard times, Lucia offers a solution and finds herself at the centre of an archeological discovery.
Lucia reaches the end of her excavations and begins to see the fruits of her political endeavours.
The floods hit Tilling and the Mapp-Flints find themselves once again at the mercy of Lucia.
Georgie makes an unexpected proposal.
