The pastimes of the young, idle rich are disrupted with the onset of a new world war, which eventually overtakes their lives in often devastating ways. Among them are eccentric Agatha Runcible, whose wild ways eventually lead her to being committed in a mental institution Miles Maitland, who is forced to flee the country to avoid prosecution for his homosexuality Sneath, a paparazzo who chronicles the wicked ways of the young and reckless and Ginger Littlejohn, Nina's former beau, who ingratiates himself back into her life, much to Adam's dismay. Meanwhile, Adam and Nina are part of a young and decadent crowd, whose lives are dedicated to wild parties, alcohol, cocaine, and the latest gossip reported by columnist Simon Balcairn, known to his readers as Mr Chatterbox. Anxious to wed Nina, Adam agrees, and the horse wins at odds of 33–1, but it takes him more than a decade to collect his winnings. In the lounge of the hotel where he lives, he wins £1,000 by successfully performing a trick involving sleight of hand, and the Major offers to place the money on the decidedly ill-favoured Indian Runner in a forthcoming horserace.

When Adam's novel Bright Young Things, commissioned by tabloid newspaper magnate Lord Monomark, is confiscated by HM customs officers at the port of Dover for being too racy, he finds himself in a precarious financial situation that may force him to postpone his marriage. The primary characters are earnest aspiring novelist Adam Fenwick-Symes and his fiancée, Nina Blount.
