Sister noon

San Francisco in the 1890s is a town of contradictions, home to a respectable middle class, but with the Wild West lingering in the imagination, and even the behaviour, of some residents. Lizzie Hayes, a seemingly docile, middle-aged spinster, is praised for her volunteer work with the Ladies' Relief and Protection Society Home, or the Brown Ark. She doesn't know it, but she's waiting for the spark that will liberate her from convention. When the wealthy and well-connected but ill-reputed Mary Ellen Pleasant shows up at the Brown Ark with an orphan in tow, Lizzie is drawn to them both.
