The Edwardian era pushes the three modern families to their limits.
There is a rude awakening for the Polo-playing Meadows family, who take on the role of being an Edwardian working-class family and must cope with the impact of poverty on their lives, as they and their two daughters adapt to a new role as breadwinners.
The Taylor family live the lives of their ancestors as an upper-middle-class Edwardian household. Formality and etiquette mean the Taylor family must live very separate lives and mum Adele struggles as her familiar role as wife and working mum is stripped away.
Finally, the Golding family are desperately hanging on to their newly acquired social status as a middle-class family, but for dad Ian it is a chance to put his theories on the benefits of discipline into practice.
