The whole family go on holiday to France, a holiday which gets off to a bad start. However, when the family car is seen to have a crest on it, it is assumed that they are titled nobility. Mademoiselle Dupont, the pension's owner, calls Pop 'Milord' and gives him and Ma her bedroom. Even the grumpy receptionist is respectful. Primrose, the second eldest daughter, falls for local boy Marc-Antoine but Charley is annoyed to see his wife cavorting with skimpily clad French hunks on the beach.

A jealous Charley gets drunk when Mariette refuses to go on the local miniature railway, preferring to stay on the beach with the admiring local boys. Pop sobers him up and effects a reconciliation. Mariette finally agrees to go on the railway and enjoys it. Angela Snow and her sister Iris, who are also on holiday in the area, organize a first wedding anniversary party for the Charltons.

The Larkin family plan the quintessential English Christmas, with food, drink and presents galore.

Mariette gives birth to a boy, John Blenheim, and, when the vicar, Reverend Candy, comes to see about the christening, he persuades the Larkins to have all their children baptised. Primrose takes an immediate shine to the young parson. Pop buys some jumble from elderly Mrs. Meredith and comes up against her nephew, Captain Broadbent, who accuses Pop of swindling his aunt when, in fact, Broadbent is the swindler, anxious to get his hands on his aunt's antique vase.

Pop comes across a fun-fair owned by his friend Fruity Pears, though it is losing money. Fruity tells off two teddy boys for causing trouble and they attack and hospitalize him, also injuring Pop. Mademoiselle Dupont arrives to be a godmother at the christenings and is initially upset to find that Pop is not a lord, but he apologizes and she ends up having an enjoyable stay. Pop buys the fun-fair and installs it in his yard where everyone celebrates after the church service.

Whilst Pop buys the adjacent quarry to stock as a trout farm and Charley considers buying a hop farm to supply the local brewery the main news in the village is the arrival of Pieter, a handsome Dane who endears himself to everyone - except perhaps Charley who is resentful of his wife's enthusiasm - with his willingness to work and his skill as a jack of all trades. Until, that is, Charley inadvertently exposes him as being a German, who pretends to be Danish to field hostility following the war.

Ma and Pop have a serious think about sending two of the kids, Zinnia and Petunia, to boarding school, but the girls themselves of course are none too keen.

Charley and Mariette decide to buy the brewery; the whole family repairs the twins' boarding school.
