 After Harry Callahan put an end to the  Scorpio  murderer, he finds himself taking on a different kind of criminal; the kind that carries a badge. When a man acquitted of murder on a legal technicality is found dead along with his lawyer, chauffeur, and bodyguard, Harry and his new partner  Early  Smith start to investigate but are ordered off by Harry s boss, Lt. Neil Briggs - a man who Harry despises because of his bleeding-heart approach to law enforcement. Soon after, a mafia figure and several of his family & friends are gunned down at a pool party, and a drug dealer is also murdered. While this is going on, Harry & Early stop an aircraft hijacking and a liquor store robbery. After a well-known pimp is murdered - in circumstances that point to a traffic stop - Harry & Early are reassigned by Briggs to investigate the homicides. When Harry is tasked with arresting mob boss Frank Palancio, the result is a bloodbath in which both Palancio and a young police officer are killed. In addition, Harry s friend & fellow cop Charlie McCoy is savagely murdered - by another cop! Things heat up even more when Harry discovers a bomb in his mailbox - and Harry finds himself in serious trouble when his boss pulls a gun on him. Now Harry must fight for his life against the crooked cops and his traitorous boss.
