The Major invites the Buckets for a golfing weekend at a luxury hotel. All is well until Onslow and Daisy turn up unexpectedly to collect Rose after she has spent a raunchy weekend away with a Mr Smith. Inevitably, when Hyacinth realises her family are there, she fears for her social standing. Adding to her dilemma is the amorous intentions of the Major.

Hyacinth and Richard spend the weekend on a yacht.

Hyacinth organises a riverside picnic, much to the despair of those invited. Despite Emett's and the Vicar's best efforts to tell Hyacinth they are unable to attend, they find getting out of Hyacinth's function impossible. As always, Hyacinth's plans of perfection are shattered when a digger dumps dirt in her chosen location for the picnic.

Hyacinth is dreading an invite to Onslow's birthday party, but changes her mind when finding out she and Richard will be picked up by Rose's wealthy Greek boyfriend. Thus Hyacinth holds a gathering at her house to impress the neighbours as she departs in the luxury vehicle. However her hopes die when a hearse arrives instead.

Hyacinth and Richard visit a stately home where the leading lady hopes to meet a member of the aristocratic family. However she fears her social status will be sabotaged by Onslow, Daisy and Rose, who turn up unexpectedly. Thus Hyacinth drags Richard through the ground's private gardens to hide from the lower-class clan.

Hyacinth takes a trip to the travel agents for some "quality" holiday brochures. Afterwards, Onslow decides to take Richard in hand and show him how to 'enjoy' life.

Richard is terrified to wake up to see Hyacinth smiling at him; he later realises he has forgotten his and Hyacinth's wedding anniversary. Richard then decides to have an alarm system installed, claiming it is Hyacinth's "surprise" anniversary present.

Hyacinth's "Daddy" is put into an ambulance and taken to hospital, after getting injured chasing after the milk woman naked on her bike. After visiting him, Hyacinth returns home and is visited by the gas man, whose life she makes difficult.

Hyacinth is determined to create the perfect impression when inviting the new Vicar for “tea and light refreshments”. However her hopes come crashing down on her when Onslow and Daisy turn up with the news Daddy has been kidnapped by a gypsy. The day gets even worse for the polish-perfecting protagonist when Rose turns up, on her way to her own funeral.

It is Liz and Hyacinth's day to help Mrs Nugent at the charity shop, and on their way there, Hyacinth has to make a visit to Onslow and Daisy's to remove a woman (played by Gretchen Franklin) from Daddy's room, refusing to leave. Meanwhile Rose intends to give up men, and arrives at the charity shop to donate her raunchy underwear.

Hyacinth and Richard drive a wealthy Mrs Fortescue into town, however Hyacinth's plans to impress are crushed by her family when Daisy and Rose flag down the Buckets for a lift. Eventually to Hyacinth's dismay, this leads to Mrs Fortescue playing darts with Onslow in a public house.

Hyacinth wants to impress Emmet with her musical talents at an elaborate musical supper. However her plans backfire when a short-skirted Rose turns up, followed by two aggressive men who begin fighting on Hyacinth's doorstep.

Hyacinth's brother-in-law Bruce is stuck up a tree, Daddy goes to the register office to be married and Emmett meets Daisy, Onslow and Rose, throwing Hyacinth into dismay. Liz offers to drive Daddy back to Daisy's, but to avoid herself and Emmett seeing how Daisy and Onslow live, Hyacinth insists they stop off at Violet's.

Richard is offered early retirement and so ponders over the possibility of having to spend all day everyday with Hyacinth. Emmett is enraged when Hyacinth ends up rehearsing a performance for the old people at the Church Hall with him, and a tranquilised Rose arrives at the scene wanting to become a nun.

Richard is not looking forward to going to a country house sale with Hyacinth as he believes she will spend beyond their limit. Liz and brother Emmett are also going to the sale, and are devastated when they realise Hyacinth is there. Meanwhile, a Mrs Braddock has commandeered Onslow’s car and is impersonating his dog, which has gone missing.

Hyacinth has put an advert in the local newspaper to teach people social etiquette, however an excited Hyacinth does not quite get what she expected.

Hyacinth gets a chance to try some social climbing while borrowing her sister Violet's cottage for the weekend.

Hyacinth decides that Richard should get a new hobby... and so insists he uses the camera that his boss presented to him when he retired!

Hyacinth volunteers to look after the old people in an outing to the funfair, however a certain old man proves to be quite a handful. As the day progresses, Hyacinth ends up in a mirror house, on some dodgems and on a ghost train.

Hyacinth sings to her hearts content when discovering Emmett's latest musical The Boyfriend is in production. Meanwhile Daddy is once again back in the war and guarding Onslow’s house with a sharp object.

A "luxury barbecue" at Violet's house looks like being a disaster because Bruce and Violet keep having violent arguments. Hyacinth organises a sing song in an attempt to take everyone's mind off their hosts' battle. Later, Hyacinth goes along to a rehearsal of "The Boy Friend" to offer her services to Emmet.

In an attempt to make Onslow jealous, Daisy finds herself a toyboy. However the plan fails and Daisy sends Onslow to the Church hall to meet Richard, in a final ploy to get him to notice her antics.

Daisy and Onslow’s granddaughter Kylie is getting christened, but Hyacinth is unimpressed because there has not been a wedding first. The day does not get any better for Hyacinth when she and Richard are forced to come to the rescue of the baby's mother Stephanie, whose transport has broken down. The leading lady then learns the baby's mother is a hippie, who is unaware of the baby’s father.

Hyacinth drags Richard off into the countryside in search of the remains of an Iron Age settlement.

Hyacinth is completely insulted when she is awarded second prize at the local craft fair, and over Lydia Hawksworth. Scandalized even further when she and Richard are overtaken by Lydia's new car, it isn't long before Richard's worst fears are realized and Hyacinth sets her sights on a newer, more expensive Rolls Royce.
