In 1908 Agnes Towler, a shop girl at Gamages store, is sacked after a flamboyant American customer insists she empty her entire stock of gloves on her counter but later receives an expensive pair of gloves from the man. He is Harry Selfridge, a former shop worker who has moved from Chicago to London with his mother Lois, wife Rose and their children. His aim is to open his own store in Oxford Street. When his original partner backs out journalist Frank Edwards introduces Harry to influential suffragette Lady Mae Loxton, through whom he obtains the required financial backing. In March 1909 he opens his unprecedently sumptuous new department store. He employs Agnes, making her senior accessories assistant, which annoys fellow shop girls Doris and Kitty, though Victor, a waiter at the store's restaurant, takes a shine to her. Also on the staff are chief accountant Mr Crabb, stoic chief of staff Mr Grove, head window dresser Henri Leclair, the formidable Miss Mardle, head of accessories ... Written by don @ minifie-1

Agnes gets her younger brother George work in the warehouse at the store but the siblings get a nasty shock when their brutish, drunken father Reg turns up and they reluctantly let him stay. Feeling alienated from her husband's business Rose goes to the National Gallery and strikers up a friendship with handsome young artist Roddy, though she is taken aback when he makes a pass at her. The store is not doing as well as Harry had hoped and he needs a gimmick to attract trade. He therefore approaches the cross-Channel aviator Louis Bleriot and display Bleriot's plane at Selfridge's. This is a huge success with Ellen Page sitting in the cockpit modelling flying scarves - which sell out as a result. Lady Mae asks for a free suit for her young lover Tony, reminding Harry of his debt to her whilst Harry himself, though determined to give Rose more attention, is caught in a compromising situation in Ellen's dressing-room. After this he buys her a house in St. John's Wood. Written by don @ minifie-1

Harry shocks his staff by suggesting that all beauty products should be put on display, rather than behind the counter, with perfumes at the fore to mask street smells. Display organizer Henri brings in his old flame, Valerie Maurel, an advertising agent for consultation and, although she hints at caution, Harry gets his way. However Henri also sees that Agnes has a talent and uses her designs and not Ellen's photographs in the display window. Agnes is experiencing domestic troubles though, due to Reg's drinking. Lady Mae forces Harry to cancel Tony's gambling debts as well as getting him to support the Suffragette movement by allowing them to meet weekly at the store. Written by don @ minifie-1

When Valerie reappears at the store Agnes gives Henri her blessing to see her and gets on with the window display marking explorer Ernest Shackleton's lecture to be given at Selfridge's. Unemployed, Frank is refused a job by Harry and goes to see Ellen, about to open in Tony's play.

Agnes is disappointed but finds consolation with Victor. The king's shopping trip is a success and he invites the Selfridges as his guests to see Ellen's new play.
