Magnum Force

After taking down the deranged Scorpio Killer in Dirty Harry (1971), the nonconformist but effective San Francisco police officer, Inspector "Dirty" Harry Callahan, is perplexed by a series of killings of known criminals. Having noticed that all homicides have been committed by a .357 Magnum, the weapon of choice by the SFPD force, Callahan suspects that there might be cops responsible for wiping out crime bosses. This time, stone-faced, no-nonsense Harry will have to go to great lengths to shed light on the string of murders, not knowing, however, how deep the corruption goes. Could there be an extreme vigilante in their midst?
