The British Women's Association for the Eradication of Vice is riven by factional dispute as to the most effective way to repress and control male sexuality. The hapless Archie Duntisbourne finds himself caught between the faction of his cock-teasing fiance, Miss Alyssa Bucklesham, and that of his cruel tormentrix Miss Evelyn Harper, as each seeks to recruit him to spy on the plans of the other. But the women of Mrs Hennessey's anarcho-syndicalist brothel, who are dedicated enemies of the Association, have other plans for Archie.
