绵阳1.10大案四年未破，贺延龄（黄志忠 饰）带领侦破组赴滨江秘密侦查。在1．10大案凶手归案的假象下，贺延龄做出结论:绵阳有一个非同一般的黑社会犯罪集团组织，无恶不作，刘唐（何平 饰）为其首犯，其罗织的庞大关系网无处不在，充当其保护伞。中央领导及公安部领导为之震惊，指示政法机关全力以赴,排除一切阻力，打掉这个涉黑团伙,对于保护伞不管其职位多高、权力多大，都必须遵纪守法。中央政法委迅即从全国调兵遣将，成立以贺延龄为首的专案组对黑社会犯罪集团和其保护伞展开攻坚战。刘唐不惜一切手段逃避打击，谋害证人和知情者，将滨江公安局副局长徐望东（张译 饰）等拉下水充当其帮凶，并利用强大关系网向侦破组施压。贺延龄及专案组顶住压力和威胁，与犯罪集团斗智斗勇，针锋相对，抱着为神圣使命甘愿牺牲一切的精神，终将该黑社会组织一网打尽。
