罗伊克莱顿是FBI的一个普通探员，他为人本分刚正不阿，认为那些特工行动政治阴谋只不过是电影小说里的噱头。在一次联合行动中，罗伊与同事马克斯和GIA探员卡特组成特遣队，但是探员和罗伊之间的办事风格大相径庭，探员做事有浓厚的个人风格，坚持自己的主观判断，但是同事马斯克则是一个行动派，做事果断且不留情面，于是在合作过程中也多有摩擦。这时，三个大案的线索都指向了美国特种部队军官塞莫·霍恩，这个人不仅有超高的作案手法，对警方的断案手段也十分熟悉，使得他每次都能在复杂的案件中全身而退，让罗伊充满了无力感。众人准备对塞莫进行追捕，罗伊却发现了案件中的诸多疑点，甚至颠覆了整个案件的根本，但是事已至此事情已经不能向着他能控制的地方发展。

Roy Clay An ordinary agent of the FBI, Dunton is a man of integrity who believes that those secret agents' political plots are just gimmicks in movie novels. In a joint operation, Roy formed a task force with his colleague Max and GIA agent Carter, but the working styles of the agent and Roy were quite different. Colleague Musk is an activist, decisive and merciless in his work, so there are many frictions in the cooperation process. At this time, the clues of the three major cases all point to the US Special Forces officer Seymour Horn. Retreating from the case filled Roy with a sense of powerlessness. Everyone was going to hunt down Seymour, but Roy discovered many doubts in the case, and even overturned the root of the whole case
