Sisters in love. A family at war. A city in peril.
Rose and Myrtle Sylvester look up to their older sister, Peggy. She is the sensible, reliable one in the household of women headed by their grandmother, Grace Booth, and their mother, Mary Sylvester. When war is declared in 1939 they must face the hardships together and huge changes in their lives are inevitable.
For Rose, there is the chance to fulfil her dream of becoming a clippie on Sheffield's trams like Peggy. But for Myrtle, the studious, clever one in the family, war may shatter her ambitions. When the tram on which she is a conductress is caught in a bomb blast, Peggy bravely helps to rescue her passengers. One of them is a young soldier, Terry Price, and he and Peggy begin courting.
