Downton Abbey is back again. Three years after the 2019 movie that extended the popular TV series, the Crawleys are once again dealing with the clash of the old ways and the new ways. This time, the interloper is early Hollywood. While a director, a crew, and a bunch of actors descend upon the estate for filming, the story also travels to the south of France for a story that might reveal secrets from the Dowager Countess' past.
