Set in Victorian England, North and South is the story of Margaret Hale, a young woman whose life is turned upside down when her family relocates to northern England. As an outsider from the agricultural south, Margaret is initially shocked by the aggressive northerners of the dirty, smoky industrial town of Milton. But as she adapts to her new home, she defies social conventions with her ready sympathy and defense of the working poor. Her passionate advocacy leads her to repeatedly clash with charismatic mill owner John Thornton over his treatment of his workers. While Margaret denies her growing attraction to him, Thornton agonizes over his foolish passion for her, in spite of their heated disagreements. As tensions mount between them, a violent unionization strike explodes in Milton, leaving everyone to deal with the aftermath in the town and in their personal lives.
