Season Four, set in 1922, sees the return of our much-loved characters in the sumptuous setting of DOWNTON ABBEY. As they face new challenges, the Crawley family and the servants who work for them remain inextricably intertwined. Six months after Matthew's tragic death, his loss is still felt throughout the great house. Mary struggles to face a new future with her fatherless child, and is encouraged by the family to pick up the pieces. Accepting a new role on the estate, the now-eligible Mary also finds herself the reluctant object of attention from a number of eager suitors. With the twenties in full swing and the tides of change sweeping through Downton, Rose's continued attraction to the bright lights of London spells trouble for the Crawleys, and Edith's budding relationship with Michael Gregson is threatened by events beyond her control. Meanwhile, below stairs, passions run high and young hearts look set to be broken. Writer and creator Julian Fellowes brings back this most-watched drama in PBS history for it's fourth gripping season. The acclaimed ensemble cast is led by Hugh Bonneville, Elizabeth McGovern, Michelle Dockery, and Maggie Smith, along with returning guest star Shirley MacLaine and new guest star Paul Giamatti as Cora's playboy brother Harold.
