In the 1830's in northern England, Riah Millican, a widow with three children, takes a job as housekeeper to a reclusive former teacher, Percival Miller. Miller makes Riah the gift of a black velvet gown, and even educates her children. But when Riah discovers the reason behind Miller's gifts, she vows to leave his house, but Miller has a hold on her, even after his death, when he leaves his house to her on the condition that she never marry. Riah's daughter, Biddy, grows up and becomes a laundress in a large house where her education keeps her from fitting in and makes her a target. But it also catches the eye of a son of the house, and with Miller's legacies, Biddy may yet find her way to happiness.
In northern England around 1900, the worker John O'Brien lives near poverty in a small house in the worker's district. He falls in love with Mary, the teacher of his highly intelligent younger sister Kathy and daughter of a rich family. Their love is doomed by the social difference, but the vigorous Mary refuses to allow outer circumstances destroying their love.
