Harry Callahan is a tough, streetwise San Francisco cop whom they call DIRTY HARRY. In this action classic, you'll see why - and also why Clint Eastwood's reputation as a premier film star and moviemaker is secure. A rooftop sniper (Andy Robinson) calling himself Scorpio has killed twice and holds the city ransom with the threat of killing again. Harry will nail him...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 most gripping police thrillers ever made.
