铁证悬案 第五季

《铁证悬案》的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”(Cold Case)。

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。

和同在CBS门下的《犯罪现场》不同，《铁证悬案》最大的魅力不在于近于真实的犯罪描写，而在于展示人在不得不面对记忆时复杂的心理活动；而和《CSI》类似的是，这部剧也展现通过细小线索拼凑事实真相的复杂过程，由于对当事人的身世和性格有更多的表现，所以最终的谜底往往更震撼人心。

COLD CASE is a drama about Lilly Rush (Kathryn Morris), the lone female detective in the Philadelphia homicide squad who finds her niche when she's assigned to "cold cases"--crimes that have never been solved. Previously, she used her instinctive understanding of the criminal mind on current murders. Now, she's interrogating witnesses whose lives and circumstances have since changed, making use of today's new science and finding fresh clues to solve cases that were previously unsolvable, all of which appeals to this smart, driven detective. She's also prepared for the consequences: that her work will open up old wounds and may lead suspects to commit new crimes. When she hits a dead end, Rush seeks advice from her respected mentor, Lt. John Stillman (John Finn). Also on the team are Det. Scotty Valens (Danny Pino), Rush's confident and strong-willed partner; Det. Will Jeffries (Thom Barry), who's been around long enough to serve as Lilly's link to the past; and Det. Nick Vera (Jeremy Ratchford), a tough cop who's considered the go-to guy for getting a confession. Rush sees her assignment as a turning point in her career when she decides to make it her business to make sure that no victim is ever forgotten.
