Welcome to Downton Abbey, the splendid ancestral home of the Earl and Countess of Grantham (Hugh Bonneville and Elizabeth McGovern) and their daughters, who live there under the watchful eye of the Dowager Countess (Dame Maggie Smith). The household is a complicated community, with the servants below stairs as fiercely jealous of their ranks as anyone above. From the sinking of the Titanic to the First World War, the secure and ordered world of Downton is rocked as the lives of the inhabitants are shaped by romance, ambition, and heartbreak.
