Lady Caroline is happy to be back amid the swirl of London society, guiding her employer's daughter, Dorothy Frogerton, through her first Season. Dorothy has been declared "an original" by a patron of the exclusive social club, Almack's, and is sifting through potential suitors. Mrs. Frogerton, meanwhile, finds her own diversions, including spiritualist gatherings at the home of Madam Lavinia, and begs Caroline to come along.
