San Francisco's "Dirty Harry" Callahan (Clint Eastwood) makes criminals pay for their crimes his way (due process be damned) as he pursues a mysterious vigilante killer (Sondra Locke), as well as a powerful crime lord (Michael V. Gazzo) and his soldiers, from the City by the Bay to San Paulo. Feverish fourth entry in the franchise co-stars Pat Hingle, Bradford Dillman, Paul Drake, and Albert Popwell as the crook who "makes Harry's day"; directed by Eastwood. 117 min. Widescreen (Enhanced); Soundtrack: English. Region Free
