Business carries on at Selfridges, where German-made goods are being replaced with English products. Harry organizes a patriotic concert to benefit the troops, featuring a popular music hall tenor (portrayed by Alfie Boe) who gets Lady Mae (his former stage partner) to join him. Miss Mardle's new lodger, a Belgian violinist, also participates in the concert, raising some eyebrows. Amid the festivities, a complex drama unfolds that sets the future course of events for Henri and Harry—all while the unsuspecting audience sings "It's a Long Way to Tipperary." It's a very long way indeed.

Harry returns, making a revelation concerning the press rumors surrounding his absence. Delphine creates a stir by arranging a spending spree by Keystone Studios head Mack Sennett, his biggest star, Mabel Normand, and a bevy of Sennett bathing beauties, who are all on a junket to London. Meanwhile, Henri is spared a legal dilemma only to land in a romantic one. Miss Mardle also faces a love quandry, and Lady Mae has trouble exiting from her miserable marriage.
