The novel depicts a post-apocalyptic society that has sought to banish privilege and envy, to the extent that people will even have their faces surgically altered in order to appear neither too beautiful nor too ugly.
Her resultant guilt, along with subsequent events—her forbidden delight at the idea of "height" during an excursion to the ruined tower of Ely Cathedral; her injury in a planned motor-coach accident during her return from the excursion; her rescue by the Inspector Michael, with whom she falls in love; and her involuntary "Betafication" at the hospital to which she is taken—provokes her rebellious spirit, and she forms a resistance group whose aim is to undermine the regime and show it up as ridiculous.
In her desire to find and kill the Dictator, she writes an article urging that anyone should be able to challenge another person on the street to bare their chest and prove they have no birthmarks.
Then, amidst sounds of a rainstorm outside, there is a knock at her door, which she opens to reveal an old lady who had been kind to her when she was hospitalised, clearly weak with hunger and soaked from heavy rain.
The novel ends with Jael, seemingly having accepted the offer from the Dictator, starting to address the public, through Michael's voice, for the first time.
Burgess described the novel as "A brilliant projection of tendencies apparent in the post-war British welfare state ... Hartley was a fine writer with a strong moral sense".
[1] The Times was equally lavish in its praise, describing Hartley's vision in the novel as "a brilliantly witty survey of certain contemporary trends and weaknesses".
