In the shadow of a love lost and being disgraced by her actions, Netta Nichol must watch from the sidelines as her child is brought up by her father and stepmother. This is not the first time her stepmother has taken what is rightfully hers. First it was her dead mother's rainbow necklace - Netta's only legacy - now her son. Netta is unable to protest such treatment, for it is 1945 and, in the eyes of her God-fearing community, she is doubly cursed: an unmarried mother who struggled with mental health problems after giving birth to her son. After being banished from her beloved Galloway, to a Yorkshire mill-town, Netta is determined to show she is capable of building a life for herself, so she can return to Galloway and claim back her child.
