The film starts with a tram being driven and conducted by women. The journey continues as the women driver prepares the tram and we then see the women conductor taking tickets on the top deck.   When the Great War started most people thought it would be a short war. It was soon clear that this was not the case. It would be a long industrial war. The ability to make guns, shells, ships and aircraft would be just as important as the tactics on the battlefield. Britain was soon in need of more workers to fill the gap. By the end of the war around 2 million women workers stepped in to carry out much needed work. They served as clerks, drivers and also worked in engineering and munitions. Yet again we see examples of women in positions of responsibility and authority that would have been unthinkable before the war.
