In a Yorkshire mill town in 1931, Lily Briggs works hard at Calvert Mill to make ends meet and take care of her parents and younger siblings. Saturday nights at the dance hall keep Lily upbeat, and now there's a blossoming romance with childhood friend Harry Bainbridge to put an extra spring in her step, too. But then a run of misfortune threatens Lily's work, home and personal life, and she has to rely on the community at the mill for support. With so many others to worry about, will Lily always put them first, or can she find her own happy ending?
