Trainee midwife Bethan Powell lives in the shadow of the workhouse during the Depression. It's difficult to say which is harder for her and fellow nurse Laura Ronconi - their grueling work in the hospital, or the frictions and financial hardships at home. Bethan's Communist miner father, rigidly Chapel mother, unruly brothers, and delightful but dubiously honest aunt, and Laura's vast Italian cafe-running family, cause the girls as much worry as any difficult case or strict ward sister.
