The American Gilded Age was a period of immense economic change, of great conflict between the old ways and brand new systems, and of huge fortunes made and lost. Against the backdrop of this transformation, our story begins in 1882 with young Marian Brook (Louisa Jacobson) moving from rural Pennsylvania to New York City after the death of her father to live with her thoroughly old money aunts Agnes van Rhijn (Christine Baranski) and Ada Brook (Cynthia Nixon). Accompanied by Peggy Scott (Denée Benton), an aspiring writer seeking a fresh start, Marian inadvertently becomes enmeshed in a social war between one of her aunts, a scion of the old money set, and her stupendously rich neighbours, a ruthless railroad tycoon and his ambitious wife, George (Morgan Spector) and Bertha Russell (Carrie Coon). Exposed to a world on the brink of the modern age, will Marian follow the established rules of society, or forge her own path? The Gilded Age - Tuesday at 9.00pm on Sky Atlantic.
