It's the dawn of the 1930s, and the three privileged Guinness sisters, Aileen, Maureen and Oonagh, settle into becoming wives and mothers: Aileen in Luttrellstown Castle outside Dublin, Maureen in Clandeboye in Northern Ireland and Oonagh in Rutland Place in London.

But while Britain becomes increasingly politically polarised, Aileen, Maureen and Oonagh discover conflict within their own marriages.

As affairs are uncovered and secrets exposed, the three women begin to realise that their guiled upbringing could not have prepared them for the realities of married life, nor for the scandals that seem to follow them around.
