成长于英国南部田园风光中的玛格丽特（丹妮拉·丹拜-阿什 Daniela Denby-Ashe 饰）因为作为牧师的父亲辞了工作，一家人搬到了全然陌生的北方小镇米尔顿。不同于南方的温暖舒适，处于工业革命时期的米尔顿阴冷又脏乱。路上不再是芳香花草，取而代之的是粗鲁的工人，棉絮 飞舞的纺织车间。除了新环境的不适应，还有来自纺织厂的厂主——年轻的实业家约翰桑顿（理查德·阿米蒂奇 Richard Armitage 饰）的盛气凌人及对工人的苛刻，这让玛格丽特对桑顿的第一印象极其糟糕。 随着米尔顿生活的加深，玛格丽特渐渐认识到工人粗鲁暴脾气背后的温柔和疾苦，坚定的站在他们一边。和其立场相反的雇主桑顿则对玛格丽特一见钟情，但不善表达的他似乎在无形中把玛格丽特越推越远。二人如同南方与北方，截然相反但又紧密相连……

Lord Robert Crawley and his family live a life of leisure, while a fleet of servants, including butler Carson, attend to their every need. But two events conspire to shake things up: the sinking of the Titanic, which claims Crawley's heirs, and the return of his valet, Bates. Since Crawley and Lady Cora have three daughters, his distant solicitor cousin, Matthew, becomes heir to the estate. With that, the scheming begins, since Thomas the footman views Bates as an interloper and Crawley's mother, Violet, feels the same way about Matthew's mother, Isobel.
