In one of his signature roles, Clint Eastwood plays a streetwise San Francisco police detective who gets the job done. A rooftop sniper (Andy Robinson) calling himself Scorpio has killed twice. Now he's buried a young women alive and threatens to let her suffocate unless the city pays ransom. Harry Callahan will nail the prep..one way or the other... no matter what "the system" prescribes. Filming on location, director Don Siegel made the City by the Bay a vital part of Dirty Harry, a practice continued in its four sequels. The original remains one of the best police thrillers ever made.
