It's 1985 and Princess Margaret is at an all-time low. She's lonely, her health is failing, and she loses her status as Councillor of State when Prince Edward turns 21. At her lowest point, Margaret discovers a terrible family secret that two of her first cousins who she believed dead have been institutionalised for decades. In search of answers, she comes to believe that it is not just the cousins who have been cast aside by the family, but all those who don't fit in.

In this episode, Edith Bowman talks with director Jessica Hobbs, Head of Research Annie Sulzberger and the actor who plays Princess Margaret, Helena Bonham Carter.
