Lancashire, 1936. With her son Gabriel finally married, and her youngest following his dreams of becoming a doctor, Gwynneth Harte finds herself with an empty nest - until a fire forces her to move in with Gabriel and his wife Maisie at their home on Daisy Street. Arthur Chapman has been at a low ebb ever since the death of his wife. Turning to drink in his grief, he lost both his job and contact with his grandchild, Beatie - but now the inheritance of a house from a distant relative is the fresh start he needs. When Beatie runs away from her cruel grandmother and takes refuge with Gwynneth, she and Arthur are thrown together - and find themselves growing closer. But trouble is brewing in the valley. Can the residents of Backshaw Moss band together to keep each other safe, and will there be wedding bells on Daisy Street?
