Detailing the daily lives, responsibilities, and dress of the upper class, Alastair Bruce, historical Downton Abbey advisor, takes us on a journey through 1900s Britain.

二小姐结婚了，大小姐怀孕了，两姐妹也和解了。柯拉在医院的工作得到了丈夫与老太太的认可，亨利和汤姆合开了汽车公司，伊莎贝尔表亲与默顿伯爵准备结婚。安娜生了孩子，卡森半退休，巴罗即将成为庄园的管家，黛西和安德鲁确认了心意。莫斯利辞去男仆的职位，正式做了老师。从此以后，所有人都过上了幸福的生活。

Our time with the Crawleys draws to a close and we see what will finally become of them all. Secrets and rifts threaten the unity of the family, while those below stairs continue to navigate social changes which put their futures in jeopardy. Will Mary choose the right path? Will her sister Edith finally get a break?! Will Carson and Mrs Hughes actually make it up the aisle? And will Anna and Bates overcome the many hurdles that have been set before them?

The beloved Crawleys and their intrepid staff prepare for the most important moment of their lives. A royal visit from the King and Queen of England will unleash scandal, romance and intrigue that will leave the future of Downton hanging in the balance.
