After losing her family in the Great War, Nell is grateful to marry Stan Hibbert, believing she can recapture a sense of family with him. But five years on, she is just another back-street housewife, making every penny do the work of tuppence and performing miracles with scrag-end. When she discovers that Stan is leading a double-life, she runs away to make a fresh start. Two years later, in 1924, Nell has carved out a fulfilling new life for herself and her young children in Manchester, where her neighbors believe she is a respectable widow and a talented machinist. But the past is hard to run from, and Nell must fight to protect the life she has made for herself and her children.
