|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, from the ambitions of the bullying local landlord to rumours of a Fascist spy. Can the residents of Backshaw Moss band together to keep each other safe, and will there be wedding bells on Daisy Street?
