The novel's title is a reference to the flow of arguments in a debate, and a series of these exchanges tell the story. Instead of a single central plot, there are a number of interlinked story lines and recurring themes. As a roman à clef, many of the characters are based on real people, most of whom Huxley knew personally, such as D. H. Lawrence, Katherine Mansfield, Sir Oswald Mosley, Nancy Cunard, and John Middleton Murry, and Huxley is depicted as the novel's novelist, Philip Quarles.
Walter Bidlake, a young journalist. A weak and ineffectual man, Walter is living with Marjorie Carling, a married woman whose husband refuses to grant her a divorce. Marjorie is pregnant with Walter's child, but their relationship is disintegrating, largely because Walter has fallen desperately in love with the sexually aggressive and independent Lucy Tantamount. His wife Ms Bidlake is inspired by Lady Ottoline Morrell.
John Bidlake, Walter's father, a painter. He is famous for his work and for his scandalous love life. However, his recent paintings show a creative decline, which he himself recognises but refuses to admit. He has an illness which is eventually diagnosed as terminal cancer.
Philip Quarles, a writer and his wife Elinor, John Bidlake's daughter. They return from India to England. Quarles is a withdrawn, cerebral man, ill at ease with the everyday world and its emotions; Elinor loves him, but is tempted to enter into an affair with the bold and attractive Everard Webley, a political demagogue and leader of his own quasi-military group, the Brotherhood of British Freemen. Quarles' father, Sidney, is unlike his son: outwardly impressive, he is in reality pretentious, feeble and self-indulgent. An undistinguished MP and failed businessman, he has retired from public life, supposedly to concentrate on writing a vast and definitive study of democracy. In fact he has written nothing, but he employs a secretary; the girl becomes pregnant by him and threatens to make a scandal. Philip and Elinor have a young son, little Phil, who becomes ill and dies of meningitis.
Mark Rampion, a writer and painter. Based on D. H. Lawrence, whom Huxley admired greatly, Rampion is a fierce critic of modern society. A full chapter in flashback shows Rampion's courtship and marriage to his wife, Mary.
Maurice Spandrell, an intellectual desperately and unsuccessfully searching for proof of the divine in his life. For years Spandrell has devoted himself to vice and deliberate wickedness in order to prompt a reaction from God. He has found some pleasure in the corruption of an innocent young girl, both in the act itself and in his own feelings of remorse, but when he is not divinely punished, he looks for an even larger sin to force God's hand. He believes that if there is no real evidence of God's existence, everything in life is pointless. He meets Illidge, a young scientist of working-class origin, and taunts him for his angry left-wing rhetoric and actual political impotence in order to persuade him into helping him murder Everard Webley. Tragically, there is still no obvious heavenly negative and personal consequences for this ultimate sin, except to strengthen Webley's Brotherhood of British Freemen. Spandrell sends an anonymous note to the Brotherhood, informing them that the murderer is at his address. He tries one last time to find God's presence in the world when he asks Rampion whether Beethoven's String Quartet No 15, played on the newly invented gramophone, is an indication or proof of God. Rampion answers that even the sublimest of music, such as Beethoven's composition that they are listening to, is not a proof of God, this motivates Spandrell to call the police, essentially committing suicide, since when they arrive he allows himself to be shot and killed, while the third movement from Beethoven's String Quartet No. 15 plays in the background.
Denis Burlap, Walter Bidlake's editor. Based on John Middleton Murry, Burlap is in his writings and public image a Christian and an anguished, self-accusing moralist; in his inner thoughts and private behaviour, however, he is calculating, avaricious and libidinous. He lives with Beatrice Gilray, who at thirty-five remains a virgin, having been molested as a young girl; for some time their relationship is platonic, but Burlap succeeds in seducing her. The novel ends with his having secured several thousand dollars for a book, St Francis and the Modern Psyche, and enjoying an evening of sensual pleasure with Beatrice.
Comparisons have been made between the character Everard Webley and his Brotherhood of British Freemen and Oswald Mosley and the British Union of Fascists. However, when Huxley wrote Point Counter Point Mosley was still a prominent member of the Labour Party, and would remain so until 1931; the BUF was not founded until 1932. A number of other fascist groups preceded Mosley, the most prominent being the British Fascists, and possibly one of those may have been Huxley's inspiration. In the 1996 reprint of Point Counter Point, Mosley's son Nicholas discusses the connection in a new introduction to the novel. David Bradshaw has argued that the most likely source for Webley is John Hargrave, founder of The Kindred of the Kibbo Kift. Aside from the question of which British Fascist leader was meant, the book having been written in 1928 means that at the time of writing Hitler and his Nazi Party were still a marginal force in German politics, and British Fascists looked mainly to Fascist Italy - which did not pose any kind of military threat to Britain That makes a difference for the act of killing the Fascist leader. While ten years later the killing of a British Fascist might have been considered a patriotic act, removing a potential collaborator with the Nazis, in 1928 such an act was simply a pure manifestation of left-wing radicalism.
