In 1763 London, women's opportunities for economic advancement are either through marriage or sex work. The city's brothels are run by canny and determined businesswomen, such as Margaret Wells (Samantha Morton) and Lydia Quigley (Lesley Manville), but there is a new morality on the rise. Religious evangelists demand the closure of brothels, and police are happy to launch brutal raids.
The show revolves around Wells' determination to improve her life and the lives of those in her "family" by moving her brothel to Greek Street in Soho to serve a wealthier clientele in Georgian society. Her move to Greek Street puts her into direct conflict with a rival madame, Lydia Quigley, for whom she had previously worked. Quigley operates an elite brothel in Golden Square that serves rich, influential people.
