Jo, the firstborn, "The General" to her 11 sisters, is the only thing the Hamilton girls have in place of a mother. She is the one who taught them how to dance, the one who gives the signal each night, as they slip out of the confines of their father's townhouse to await the cabs that will take them to the speakeasy. Together they elude their distant and controlling father, until the day he decides to marry them all off. The girls, meanwhile, continue to dance, from Salon Renaud to the Swan and, finally, the Kingfisher, the club they come to call home.
