English county of Yorkshire, early 20th century. In the Downton cottage, the aristocratic family Crawley and his servants live. The most prominent events in history, at the end of the Edwardian era (1901-1910), have an important effect on their lives. As for example that, following an event like the sinking of the Titanic, the Crawley family is seen at a crossroads. His future heir has died in this event, and since they have no sons, only three daughters, they cannot inherit. This turnaround of fortune will not please family members or servants.
