The slum dwellers have moved into the 1890s, when Britain was slowly recovering from an economic depression. Cheap foodstuffs and mass-manufactured goods have found their way into the slum's shop, but only some of the residents can afford them.
The Howarths are the lucky ones - they now have a bespoke tailor's shop, and tailor Russell can make good money catering to middle-class Londoners who couldn't afford Savile Row suits. Their relative prosperity means Mandy can turn her attention to being a respectable Victorian housewife.
The Potter family's experience reflects the lives of countless Victorian poor who struggled with low wages and irregular work, but they are offered a lifeline by their neighbour Maria who needs help with her laundry business. But a water shortage during the 1890s makes life even harder, and it forces Maria and her brother John to leave the slum.
