Tony Robinson explores the grim reality of the Victorian era, where the rapid expansion of industry and urban centers created a desperate need for labor. From the dangerous, back-breaking work of navvies building the nation's railways to the hazardous, soul-crushing tasks of child chimney sweeps and rat catchers, the program reveals the harsh, often lethal conditions faced by the ordinary people who kept Britain running. Through hands-on demonstrations and expert insights, the series uncovers the brutal, unglamorous, and often overlooked jobs that defined the lives of the working class during this transformative period in history.
