Mary-Ann Everdene, a maid at Long Livery Hall, loves sex with other girls, especially her best friend, Polly Vance. Nevertheless, she tries hard to fit the social norms through frequent sexual coupling with Colum Lanyon, the head footman. She knows that "normal" sex with Colum isn't going to work in the long run, but Mary Ann is reluctant to cast him aside while she can still enjoy threesomes with him and Polly. The crunch comes when she and Colum are chosen to accompany their master's daughter away from Long Livery, leaving Polly behind.
