Season 1 - Episode Guide

Once considered the most beautiful debutante of the 1930s, heiress Margaret Sweeny is in the midst of a divorce when she meets the dashing (and married) Ian Campbell, future Duke of Argyll. What begins as sexual chemistry evolves into something more serious when Margaret begins not only to fall in love with Ian but also his crumbling ancestral seat, Inveraray. But all is not what it seems in her marriage, and Margaret finds herself hurtling towards a scandal that will not only change her life, but the perception of the British establishment forever.

Putting aside gnawing doubts about her marriage, Margaret continues with her plan to secure her claim to Inveraray Castle. But a private photograph has the potential to destroy everything she has ever worked for, and fuel the fire of one of the most scandalous divorce trials in British history.

Battlelines are drawn as the Duke and Duchess of Argyll enter into a bloody separation, all played out in the white-hot glare of a ravenous press. As the most scandalous divorce trial of the century looms over Margaret's life and reputation, she must decide if she is to go away quietly or fight for her side of the story to finally be heard.
