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.
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.
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.
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 prepares for the Mayor's fancy dress ball and is also on a mission to impress the new neighbours, a few streets away.
Hyacinth Bucket (whose name, she insists, is pronounced "Bouquet") is a suburban housewife in the West Midlands. She would be the first to tell you that she is a gracious hostess, a respected citizen, and a well-connected member of high society. If you don't believe that, just ask her best friend Elizabeth, held captive in Hyacinth's kitchen; or the postmen and neighbours who bristle at the sound of her voice; or Richard, her weary and compliant husband. In fact, Hyacinth's reputation could be as perfect as her new lounge set, if not for her senile father's love of running wild in the nip. Oh, and she would prefer it if her brother-in-law was a sharper dresser. And that her husband was more ambitious. And that her sisters were more presentable. And do take your shoes off before you come in the house, dear. Mind that you don't brush against the wallpaper.
