In this intense continuation of the saga of the famous San Francisco cop, a group of vigilantes takes justice into their own hands, eliminating criminals that the law has let slip away. Sergeant Harry Callahan, known for his unorthodox style and disdain for bureaucracy, becomes the center of attention when a series of mysterious murders of criminals unfold in the city.
With his characteristic dark humor and unmatched marksmanship, Harry becomes involved in the investigation and quickly realizes that these vendettas are being orchestrated by a group of corrupt police officers who believe they have the moral right to exterminate those they deem unworthy of the judicial system. As the danger escalates, Callahan uncovers a plot that threatens not only his life but also the integrity of the police force itself.
As Harry attempts to stop these vigilantes, he is drawn into a game of cat and mouse, where his own colleagues seem to be on the wrong side. With a sharp focus on ethics in law enforcement, the film not only delivers thrilling action sequences but also delves into moral dilemmas, challenging viewers to question what the limits of justice are. The final confrontation is not only explosive but leaves a lasting mark on Harry's life, as he has always believed that a "vigilante" is not the same as a true defender of the law.
