Magnum Force
Inspector Harry Callahan is reassigned to homicide after his previous exploits, and immediately finds himself investigating a series of brutal, seemingly coordinated assassinations of notorious San Francisco crime figures, including a mob boss, a pimp, and a drug lord. As the body count rises and the method of execution becomes clearer, Callahan realizes these are not typical mob hits but rather meticulously planned extrajudicial killings. His investigation leads him to suspect a group of four young, highly skilled, motorcycle-riding police officers from the motorcycle patrol unit, who are disillusioned with the criminal justice system and have decided to take the law into their own hands by systematically executing those they deem beyond the reach of the courts. Callahan finds himself an unexpected target of these vigilante cops, who believe he is too old-fashioned and stands in their way. He ultimately uncovers that his own superior, Lieutenant Neil Briggs, is the mastermind behind the rogue police squad, directing their deadly missions. Callahan is forced to confront and eliminate the vigilante officers and Briggs in a violent showdown, upholding the rule of law despite his own often unconventional methods.
