Plot: When SFPD Insp. Harry Callahan ends a liquor store holdup by doing things in his usual hard-boiled manner, his bleeding-heart boss, Capt. Briggs (Bradford Dillman) demotes Harry to the personnel division. But Harry doesn't remain there for long, as a group of terrorists rob an arms warehouse and begin a bloody extortion spree demanding $2 million from the City. Harry is paired with Insp. Kate Moore (Tyne Daly) to shut the terrorists down. Callahan is none too thrilled to be paired with Moore, but she more than proves herself when she and Harry pursue the terrorists to their hideout in the old prison of Alcatraz.
