The plot focuses on a man who, ten years after his wife and daughter are brutally murdered, returns to exact justice from the assistant district attorney who prosecuted the case against their killers. His vengeance threatens not only the man who allowed mercy to supersede justice, but also the system and the city that made it so. —The Film Department
In a 1999 Philadelphia home invasion, Clarence James Darby (Christian Stolte) and his accomplice Rupert Ames (Josh Stewart) kill the wife and daughter of Clyde Alexander Shelton (Gerard Butler) before his eyes. Prosecutor Nick Rice (Jamie Foxx) is unable to use DNA hard evidence to securely convict both accused. Unwilling to take a chance on lowering his high conviction rate, he makes a deal with Darby, letting him plead guilty to a lesser charge and receive a reduced sentence in return for testifying against Ames. Ames is found guilty and is sentenced to death. Darby is released after a few years. Shelton feels betrayed by Rice's actions and by the justice system in general.
Ten years later, Ames's time on death row is up. Unknown to the prosecutors and the witnesses, the cardio-toxic drug usually used in executions has been replaced with an anti-Convulsant, causing Ames to die an extremely painful death. Evidence relating to tampering with the drug implicates Darby. An anonymous caller alerts Darby as the police draw near and directs him to a remote location. Shelton, disguised as a cop, reveals himself as the caller and paralyzes Darby with puffer fish venom. He straps Darby to a table and slowly dismembers him as revenge for murdering his wife and daughter, video-recording the gory proceedings. When Darby's remains are found, circumstantial evidence tentatively ties his death to Shelton. Despite knowing the evidence is weak, Shelton surrenders himself into police custody, where he points out the flaws in Rice's case against him.
As he leaves the interrogation room, Rice receives a phone call from his wife, and learns that Shelton had sent a copy of the Snuff film of Darby's demise to his house, traumatizing his daughter. He initially refuses to bargain with Shelton in order to get a confession. But District Attorney Jonas Cantrell (Bruce McGill) orders Rice to make a deal. In court, Shelton represents himself. He successfully argues that he should be granted bail, then berates the judge for accepting the "bulls**t" legal precedents he himself cited and for being too eager to let madmen and murderers back on the street. The judge jails Shelton for contempt of court.
Shelton demands a porterhouse steak lunch be delivered to his cell by a specific time, in return for telling where to find Darby's lawyer, who was reported missing three days earlier. Rice agrees, though the lunch is delayed by a few minutes due to the warden's pedantic security measures. Once he has his meal, Shelton provides a set of coordinates, where Rice and the others find Darby's lawyer, buried alive but suffocated when his air supply ran out while Shelton's lunch was being delayed. Shelton kills his cellmate using the steak's bone, forcing the warden to secure him in solitary confinement.
Cantrell arranges a meeting with a CIA contact and brings Rice. They learn that Shelton has previously worked with the agency, creating devices to assassinate people in imaginative ways, such as a necktie that kept getting tighter when it was tied, thus strangling the victim. Further, they are warned that Shelton is capable of killing anyone he wishes. During a meeting with Rice and Cantrell, the judge is killed when she answers her cell phone, and it explodes. A number of Rice's assistants are killed by car bombs, one of them Sarah Lowell (Leslie Bibb). As Rice and Cantrell leave the funeral of Lowell, Cantrell is killed by a bomb disposal robot converted into a weapon. The mayor (Viola Davis) puts the city under lock-down and promotes Rice to acting District Attorney.
Rice learns that Shelton owns an auto garage next to the prison. A tunnel from the garage leads to a cache of guns, disguises, and other equipment below the solitary confinement cells, and secret entrances to each cell. He and Police Detective Dunnigan (Colm Meaney) realize Shelton wanted to be in solitary, allowing him to easily leave the prison without detection and commit the murders. Evidence in the tunnel points Rice to Shelton's next target, city hall, where the mayor is holding an emergency meeting with city officials. Rice and his men cannot find Shelton but discover evidence pointing to a cell-phone-activated suitcase bomb in the room directly below the meeting.
Shelton returns to his garage after planting the city hall bomb, then returns to his cell. He is surprised to find Rice waiting for him. Rice berates Shelton for taking revenge because of the pain he suffered. Shelton suggests another deal, but Rice refuses this time, saying that he does not make deals with murderers anymore, and thanks Shelton for teaching him that. Rice and Dunnigan secure Shelton in the cell and leave. Despite being pleased that Rice had finally learned his lesson, Shelton dials the cell phone on the city hall bomb. Shelton realizes too late that Rice has moved the bomb to his cell and the cell's entrance to the tunnel has been sealed. Shelton looks upon his daughter's bracelet with a sense of sadness, accepting his fate as the bomb explodes.
