In the late 1930s Nella Last,a housewife aged 49,living in Barrow-in-Furness on the North West English coast,agrees to send details of her routine to the Mass observation project,a non-governmental scheme designed to chronicle the lives of ordinary people. When war comes Nella defies her over-protective husband to join the local Women's Voluntary Service. Initially diffident she blossoms thanks to the dominant but kindly Mrs. Waite,and enjoys her independence as a useful war worker. The film also shows her relationship with her two sons as well as the effect of the war on the community and ends by explaining that Nella kept in touch with the Mass Observation project until her death in 1968.
