在经历了上一次的恐怖袭击之后，由于政府对CTU应对恐怖事件的解决方式不太满意，还是最终决定解散CTU。杰克·鲍尔（基弗·萨瑟兰KieferSutherland饰）也因使用酷刑等非法手段来防止恐怖袭击，而受到审查。原本以为自己终将在监狱里度过余生，却因死而复生的前同事托尼（卡洛斯·博纳德CarlosBernard饰）的出现，彻底打乱了杰克现有的生活。托尼希望杰克能与他一起，共同调查又一次在美国大路上展开的恐怖袭击。而随着调查的不断深入，杰克觉得身边的托尼越来越琢磨不透。杰克一直觉得托尼有什么事情没有对他说明白。由于新总统对杰克的信任，所以他们的调查之路虽然危机重重，但是开展得还算顺利。不过，最后杰克终于发现这次恐怖袭击的幕后策划者，原来是一直与他并肩作战的朋友托尼……

一群小伙伴从小一起长大，一场塌楼意外令他们失散，也从此彻底改变他们命运。多年后再重遇的他们早已经身份悬殊、敌我难分，不过也尝试在公义和友谊之间挣扎。

故事发生在美国费城，中心人物是一个凶杀调查组，他们面临的案件不是最近发生的，而是几年前甚至十几年以前的旧案。由于发生的时间久远，加之当事人已经难以寻找，各种犯罪证据几乎已经烟消云散，所以调查起来特别困难。这样的凶杀案，被形象地称为“冷案”(ColdCase)。剧集的主角是“冷案”调查组中惟一的女探员莉莉·拉什，她凭着坚韧的性格，和队友一起寻找至今健在的当事人，抽丝剥茧地让尘年往事重新浮出水面。

英国ITV开始根据英国女作家ValMcDermid的破案小说Dr.TonyHill中的故事"MermaidsSinging"和"ShadowsRising"改编的英国悬疑破案剧集。之后又由其他人续写，后来在第四季度第二集"Torment"又改编自ValMcDermid的Dr.TonyHill中的故事"TheTormentofOthers"。Dr.TonyHill这个角色是个大学里面的法庭心理学家，他一起与一位非常干练的女刑事探员CarolJordan合作破了一个又一个非常棘手的悬疑案件！
