芝加哥警署的第21辖区有两组完全不同的警察。其中一组是穿制服的警察，负责在街道上巡逻，直接打击和处理街头犯罪行为。另一组被称作情报组，负责打击危害这座城市的主要毒瘤——黑帮犯罪、毒品走私、高级别谋杀案，诸如此类。负责领导情报组的的是Hank Voight警官（Jason Beghe）。他是一个不怕破坏规矩的人——只要能维护正义，哪怕和法律对着干他也在所不惜。他为人强悍，要求严格，只有那些能上得刀山下得火海的人才能在他的手下当差。就拿Antonio Dawson侦探（Jon Seda）来说——尽管他与上司有过一段复杂的历史，但他对于指挥这样一个团队充满雄心。即便那意味着他每天都要和Voight闹矛盾，也阻止不了他要留下来的决心。那些街头巡警每天都在盯着情报组看，他们梦想得到升职并加入这个精英团队。而对于已经身在其中的人来说，这份工作每天都意味着挑战，他们必须为这座城市保驾护航并承担巨大的责任。有些时候责任会变成压力，而压力会带来心理和情感上的创伤——走出第21辖区的办公室，走入这些侦探的个人生活，你就会明白这句话的含义。
