Watchmen

Campbell (played by James Spader) was once an excellent FBI agent, but now, he just wants to go to Chicago as soon as possible to start a peaceful retirement life there. It turns out that for the past few years, Campbell has been investigating a serial killer named Cliffin (played by Keanu Reeves). This man is different from ordinary perverted murderers. He has extremely high IQ and EQ. Every time he commits a crime, he is always able to escape at the most critical moment. Campbell, who suffered repeated failures at work, chose to give up, but Cliffen was obviously not tired of the cat-and-mouse game with the old agent. He not only followed Campbell to Chicago, but even committed one bloody murder after another there. What Campbell didn't know at this time was that Cliffin had already chosen Campbell in his heart to be his final prey.
