Number three in the Dirty Harry series, The Enforcer equips macho cop Harry Callahan (Clint Eastwood) with a female assistant, Kate Moore (Tyne Daly). Their quarry is a terrorist organization which has kidnapped the mayor of San Francisco (John Crawford). Harry goes undercover, attempting to root out the terrorists by beating up anybody who looks at him cross-eyed. When Harry and Kate discover that the mayor is being held at Alcatraz Island, it is only a matter of time before the climactic bloodbath. The Enforcer cleared enough at the box office to warrant yet another Dirty Harry opus, Sudden Impact.~ Hal Erickson, All Movie Guide
