Dirty Harry is the first screen adventure for Clint Eastwood's maverick San Francisco detective, "Dirty" Harry Callahan, which led to a series of successful sequels throughout the Seventies and Eighties. In Dirty Harry, the year is 1971 and San Francisco faces the terror of a maniac known as Scorpio -- who snipes at innocent victims and demands ransom through notes left at the scene of the crime. Inspector Harry Callahan is assigned to the case along with his newest partner Inspector Chico Gonzalez to track down Scorpio and stop him. And Callahan will get the job done... one way or the other…no matter what “the system” prescribes. Don Siegel directed this box-office blockbuster, which remains one of the best police thrillers ever made.
