From IMDB: Hard, withdrawn city cop Jim Wilson roughs up one too many suspects and is sent upstate to help investigate the murder of a young girl in the winter countryside. There he meets Mary Malden, whom he finds attractive and independent. However, Mary's brother is chief suspect in the killing. And Mary herself is blind.。本剧基于记者Justin Fenton的同名书籍创作,《火线》制片人David Simon和George Pelecanos共同打造。 故事记述了巴尔的摩警察局枪支追踪特别工作组的起起伏伏,以及一个美国城市所遭遇的腐败和道德沦丧,在这个城市里,禁毒和大规模逮捕的政策是以牺牲实际警察工作为代价的。。
