At the unfashionable end of Oxford Street in 1909 London, an American retail tycoon arrives to jettison fusty British tradition and open the biggest and finest department store the world has ever seen: Selfridges. Three-time Emmy winner Jeremy Piven (in his first television appearance since his iconic role as Hollywood agent Ari Gold in Entourage) stars as Harry Gordon Selfridge, the flamboyant entrepreneur and showman seeking to provide London's shoppers with the ultimate merchandise and the ultimate thrill.

Emmy Award-winning writer Andrew Davies (Pride and Prejudice, Bleak House) conjures the opulence and excitement of Selfridges and the story of its founder, a man of exuberant, outsized, and potentially dangerous, appetite. Behind Selfridges' lavish shop windows, gleaming counters, and majestic doors, appetite intersects with ambition and desire not just for Harry, but for his staff, his family, and the various women drawn to the store and the man. Zoe Tapper (Stage Beauty) is showgirl and temptress Ellen Love; Frances O'Connor (Madame Bovary) as is Harry's loyal wife, Rose; Gregory Fitoussi (Spiral) is the mercurial window designer extraordinaire, Henri Leclair; and Aisling Loftus (Case Histories) is the spunky shop girl Agnes Towler.

After nearly 20 years of setting trends and pushing traditions, Selfridge's is still going strong as the triumph of London's Oxford Street. But Harry's potentially dangerous appetite for entertainment and women, while always a problem, has reached its peak. Now, he struggles to keep the reins of the store he loves, in the face of old troubles, new opportunities, and unsettled scores. Mr Selfridge The Final Season, airs in nine drama-packed episodes on Sundays, March 27th - May 22nd, 2016 at 10/9c on MASTERPIECE on PBS.
