Diana, Princess of Wales, divorced wife of the Queen Elizabeth II's son Prince Charles and mother of her grandchildren Princes William and Harry, is killed in a car accident in August, 1997, causing uproar throughout the UK, not least for the royal family and the recently elected Prime Minister Tony Blair (Michael Sheen). In the aftermath, the royal family take a period of mourning in their Scottish residence, whilst Blair remains in London to almost take advantage of the situation.
