Navy team finds two missing meiju.ｐro aviators in Coral Sea, uncovering a terrorist plot.

NCIS(海军犯罪调查机构)是一部关于一支特工小组的动作剧集，这支小组隶属五角大楼的特别部门，肩负着调查任何有一丝证据证明与海军及海军陆战队人员有关的犯罪，且不论其级别或职位的高低。领导这支小组并独立于海军指挥系统的是NCIS特工Leroy Jethro Gibbs (Mark Harmon饰)，这名经验丰富的调查员与审问员是个机智、强硬并且为了完成任务愿意打破常规的人。直接受Gibbs领导的是Anthony DiNozzo特工 (Michael Weatherly饰)，作为一名前重案组探员，其出色的本能来自于大量的调查经验。之后加入他们俩的是Kate Todd (Sasha Alexander饰)，一个美丽而又坚强的前特勤处特工，曾与Gibbs短兵相接（见NCIS第一季第一集）。还有从事技术分析工作的Abby Sciuto (Pauley Perrette饰)，是一名天才科学家，她那黑色幽默与哥特风格的装扮相得益彰。新加入小队的是Timothy McGee (Sean Murray饰)，麻省理工学院（MIT，剧中经常会提到）的毕业生，他对电脑的精通使他在Gibbs率领的小组中成为一名见习特工。在小组背后默默支持的是法医Donald "Ducky" Mallard (David McCallum饰)，他见多识广。从谋杀、间谍活动到恐怖活动、盗窃潜艇，这些特工们为了调查所有与海军及海军陆战队相关的犯罪活动，足迹遍布全世界。 　　虽然同样由CBS电视网制作，NCIS却和CBS的另一王牌剧《犯罪现场》(CSI)有着极大差别，NCIS每集只专心讲述一个案子。CIS重点在于犯罪证据的收集和调查，NCIS侧重于案情的悬疑曲折以及主要角色的鲜明个性。第二季开头的一个案子就非常有代表性，一家军用直升飞机停在麦田中央，直升飞机周围的麦田全部伏倒形成了一个圆圈。而驾驶飞机的海军陆战队员则已经不知去向，这样的开头不禁一下让观众想到了外星人。不过NCIS毕竟不是《X档案》，事情的真相还是要回归到真实的生活中来。个性鲜明的几位长线角色也是NCIS吸引观众的另外一大卖点，上到调查处头头吉不斯，小到一个验尸官的助手，每一位NCIS成员都有着与人不同的特殊性格。这样一来，每位观众都能在剧中找到自己喜欢的角色。
