When FBI Agent Zack Stewart is killed, Agent John Ripley takes over the three cases he was working on, hoping one will lead to his killer. The first involves gangster Joe Walpo and Ripley finds his hideout through Joe's girl friend, Connie Anderson. Joe is killed but it is established he was 400 miles away when Stewart was murdered. The next involves a car-theft gang which Ripley breaks up by using one of the gang, Vince Angelino and his wife Julie. The last case involves Kate Martell, the victim of an extortionist who threatens to kidnap her child unless she pays him $10,000
画外音和剪辑风格类似「国防时代」宣教片，其中「硬核」的警方推断和办案过程对于当时观众来说也是难得一见的「冰山一角」，其他都流于通俗。
讲述了一个fbi探员因他的案子被杀后（我还以为这个有点帅的是男主），另一个探员接手后调查三个案子的故事。感觉罪犯过于猖狂了吧。几个女主都挺好看的，尤其演瞎子的那个。不过最后还是没说死了的那个女的和罪犯有啥关系。
过瘾的警务片。FBI宣传广告。警务片的优点一向在于行动密集没什么唧唧歪歪，个人偏好来说也觉得相对严谨的物证向警务纪实娱乐性优于容易扯淡的心证向悬疑推理。Roman那个案子单独就是一个常规悬疑片，但作为警务片就给三个案子一样的篇幅并把没用的两个排除掉，这个过程比单线的whodunit好看多了。
纪录片风格，宣传片作用，故事不难看就是了
FBI所谓洞察人性弱点就是诈胡...刑侦手段不如盲人
