NCIS是Naval Criminal Investigative Service的缩写，直译过来就是海军罪案调查处。这个隶属五角大楼的特别部门，专门从事与海军以及海军陆战队有关联的任何罪案调查。海军调查处被赋予了特殊的调查权，只要是案情需要，任何人都必须接受质询无论职务和军衔高低。NCIS小组每次都会遇到各式不同的案情，从谋杀、缉毒、谍报活动、到反恐行动、甚至是神秘宗教，无奇不有。

That conflict results in a reassignment for Givens to the U.S. District covering the town where he grew up. He is an anachronism - a tough, soft spoken gentleman who finds his quarry fascinating, but never gives an inch. Dig under his placid skin and you'll find an angry man who grew up hard in rural Kentucky, with an outlaw father, who knows a lot more about who he doesn't want to be than who he really is.
