On 20th November 1995 BBC Panorama broadcast the scoop of the century: a candid interview with Princess Diana in which she broke every protocol exposing traumas and scandal of life in the Royal Household. 25 years later, this film looks at how the broadcasting event of the century was orchestrated, what the interview revealed about modern society and new insights into the psychological portrait of Diana herself, a naive young woman who believed in the fairy-tale of her marriage only to lose her sense of self in its realities.
