San Francisco, 1971. Against the backdrop of the unhinged sniper Scorpio's deadly ultimatum, the mayor is with his back to the wall. As the murderous psychopath keeps spilling the blood of random innocents, only the uncompromising, deeply cynical, and tough-as-nails SFPD officer, Inspector Harry Callahan, can stop the Scorpio Killer. Now, partnered with the young rookie, Chico Gonzalez, Callahan must try every trick in the book to catch the assassin, in a dangerous cat-and-mouse game in the heart of the bustling city. But, this is a race against time. Can Callahan, the force's "Dirty Harry", put an end to sadistic Scorpio's reign of terror with his powerful Smith and Wesson Model 29 .44 Magnum revolver?—Nick Riganas
