DOWNTON ABBEY: THE GRAND FINALE is the story of the Crawleys going through a scandal and a change. The year is 1930. Two years after the events of DOWNTON ABBEY: A NEW ERA [2022], the Crawleys are enjoying themselves in London when news breaks out that Mary (Michelle Dockery) has… secured a divorce from Henry Talbot. Robert (Hugh Bonneville) and his wife Elizabeth McGovern (Cora) are stunned not just by the fact that their daughter hid the divorce from them but also because she gets ostracized in society. The press picks it up and hence, even the staff at Downton Abbey learns about it. The Crawleys return to Downton Abbey while Mary stays behind in London to receive her maternal uncle, Harold Levinson (Paul Giamatti). Harold arrives from New York with a mysterious friend, Gus Sambrook (Alessandro Nivola). Sparks fly between Mary and Gus in no time. On the other hand, Harold drops bad news – he has lost a lot of money in the 1929 Wall Street Crash. Hence, he is seeking to invest in Downton’s remaining assets to recoup his losses and repay his debt to Gus. What happens next forms the rest of the film.
