凡是喜欢《海军罪案调查处》的朋友对《洛杉矶》其实并不陌生－－该剧的头两集（被命名为《传奇》）本季已经插在《海军罪案调查处》正剧中播出了。《洛杉矶》主要讲述了海军罪案调查处专门从事秘密监视任务的分支部门OSP（特别项目办公室，Office of Special Project）打击高科技犯罪、逮捕最危险的罪犯并维护国家安全的故事。
加入该小组的成员都是训练有素的精英特工，他们运用尖端科技手段和各种各样的假身份秘密开展工作。他们潜藏得很深，有时连家人也不知道他们的真实身份。为了完成任务，他们不顾个人安危，每天都游走于生与死的边缘。
代号G的Callen特工（Chris O'Donnell扮演）是条「变色龙」。为了打入犯罪组织内部，他可以把自己改变成任何「需要」的形象。他的搭挡Sam Hanna特工（LL COOL J扮演）是前海豹突击队成员，曾在阿富汗和伊拉克战场上接受最残酷的实战考验。Hanna还是个监视专家，善于使用各种尖端设备。当执行外勤任务的队友需要帮助的时候，他总是能在第一时间提供决定生死的重要情报。Callen和Hanna的直接上司是OSP办公室主任Lara Macy特工（Louise Lombard），她负责计划任务的制定、调配和监控，并负责在关键时刻作出关键决定。Kensi Lo特工（Daniela Ruah扮演）奉命协助OSP开展行动。她是一位前海军陆战队员的女儿，聪明绝顶，富有激情。临床心理学专家Nate Getz（Peter Cambor扮演）则相当于小组中的「智库」，他不仅能轻易攻破任何人的心理防线，而且拥有敏锐的观察力和一流的判断力，能在任务前、任务中、任务后的不同阶段快速判别嫌疑人的精神状态和心理状态。
在危机四伏的高端犯罪领域，OSP的成员唯有依靠彼此的帮助和过硬的罪案调查技巧，才能取得一个又一个胜利。
