The general Election of 1924 brings a Labour government into power, to the consternation of Robert and Carson, though many of the staff are pleased to have a prime minister from the working class. A village delegation, building a war memorial to local dead, requests Carson, not Robert, to head its committee and the class-bound butler feels awkward, ensuring the earl is made a patron. Tim Drewe tells Lady Edith he knows that Marigold, the daughter he and his wife have adopted, is her child whilst Lady Mary receives another proposal from Tony Gillingham. Violet organizes a lunch party to match Isobel with Lord Merton though Isobel resists and at Robert and Cora's anniversary dinner supports Sarah Bunting and Tom's view that the war was futile. Robert immediately takes a dislike to Sarah. Barrow continues to pressurize Baxter to disclose damning information on John Bates but, encouraged by the adoring Molesley, she tells Cora her secret, that she was imprisoned for theft from an employer, so the plan backfires on Barrow. However, he becomes a hero for rescuing the unhappy Edith, who has accidentally started a fire in her bedroom. Subsequent evacuation leads to the discovery of young footman Jimmy nude in bed with his former employer, saucy guest Lady Anstruther.
