Harry and wife Rose have become increasingly estranged so he is left feeling over the moon after she shows up from America to celebrate the fifth anniversary of the opening of the store, but seems more interested in an exciting new friendship with a female novelist. Lady Mae is surprised by her husband's unexpected arrival in London, and after hearing him blackmail his way onto a government military committee, she suspects that he's up to something sinister.
Rumblings of war and social unrest inspire trades union activists to target Selfridge's. Harry responds by throwing a tango party to thank the staff for their hard work. He also wants to do something more public and asks Agnes to organise a Celebration of Empire in the store - but is it too much for her? Meanwhile, Rose secretly seeks out an old friend for Harry, and trouble is brewing for Lady Mae.

With German goods being taken off the store's shelves, Harry organises a patriotic concert to raise money for British troops, and Lady Mae arranges for an old friend to headline the event.
