Clyde Shelton lives with his wife and daughter in
Philadelphia when two burglars break into their home one night. Clyde is bound and gagged as he is forced to watch Clarence Darby rape and kill his wife. Rupert Ames, who only intended to steal, pleads with Darby to leave, but he stabs Clyde before raping and killing his daughter as well. Prosecutor Nick Rice is assigned to the case along with District Attorney Jonas Cantrell. Upon learning that the DNA evidence is inconclusive in linking Darby to the crime, Nick is unwilling to risk lowering his high conviction rate and agrees to a
plea bargain. Clyde begs Nick not to make a deal with Darby, but he does so anyway, boldly claiming that it is a victory. Darby testifies against Ames, who is convicted of
felony murder and is sentenced to death, while Darby pleads guilty to
third-degree murder and serves only three years in prison before being released on parole. During a press conference, Darby thanks Nick for helping him and shakes his hand as Clyde watches from afar. Ten years later, Ames expresses remorse for his role in the burglary, but maintains his innocence in the murders. Ames is executed via
lethal injection, but the procedure goes awry and he unexpectedly dies screaming and writhing in pain. Nick and Cantrell, who witnessed the botched execution, learn that the drugs were replaced with an
anticonvulsant. Meanwhile, Darby is warned by an anonymous caller that the police are coming and instructs him to flee his apartment and take an officer hostage. The officer is revealed to be Clyde in disguise, who intentionally lured Darby into a trap and had the real officer locked inside the trunk of the car. Darby attempts to shoot Clyde, but as he pulls the trigger, he is paralyzed with
tetrodotoxin coated spikes hidden inside the handle. Clyde records himself torturing and killing Darby as he is strapped to a table. After Darby's dismembered remains are found inside an abandoned warehouse owned by Clyde, he is arrested as he locks eyes with Nick. During his interrogation, Nick confronts Clyde for mailing a DVD copy of Darby's murder to Nick's daughter Denise. Clyde represents himself at his bail hearing, where Judge Laura Burch, who previously presided over Darby's plea deal, initially grants Clyde bail. When Clyde accuses Judge Burch of being too easily swayed by legal doctrine and willing to release a potential criminal, she holds him in
contempt of court and has his bail denied. After Clyde gives his confession, he demands a steak lunch from
Del Frisco's and his
iPod be delivered to his prison cell at 1:00 p.m. in exchange for the location of Darby's lawyer, Bill Reynolds, who was reported missing by his wife three days earlier. Nick agrees to the deal, but after missing Clyde's deadline, Reynolds is found buried alive with a precisely-timed oxygen device strapped to him. Simultaneously, Clyde stabs his cellmate to death while eating his lunch, forcing him to be moved to
solitary confinement. Suspicious of Clyde's skills, Nick and Cantrell meet with Bray, a
CIA contact who reveals that Clyde previously worked for the agency and specialized in unorthodox assassinations. Bray warns Nick and Cantrell that the only way to stop Clyde is to kill him. During a meeting, Nick and Cantrell persuade Judge Burch to temporarily suspend Clyde's civil rights. Judge Burch answers her cellphone, but she is killed by an explosive device hidden inside. When Nick confronts Clyde, he explains that the murders are not about revenge, but the failures of the criminal justice system. Clyde tells Nick that he will end the killings by 6:00 a.m. if he is released from prison and all charges against him are dropped. Nick takes precautionary measures instead, moving his entire legal team to an office at the prison to work throughout the night. After Clyde's deadline passes without incident, Nick allows his team to go home. While walking to his car, six attorneys from Cantrell's office, including Nick's assistant, Sarah Lowell, are killed in car bombings. Consequently, Mayor April Henry assigns two security guards to protect both Nick and Cantrell. While leaving Sarah's funeral, Cantrell and the security guards are killed by a weaponized bomb disposal robot armed with
automatic target recognition and a missile. Nick prepares to resign when Mayor Henry considers firing him, but she instead promotes him to acting District Attorney and puts the city in lockdown. After Nick learns that Clyde owns a building near the prison, he and Detective Dunnigan discover a tunnel inside that leads to a cache of guns, disguises, and other equipment below the solitary confinement cells, with secret entrances to each cell. Nick realizes that Clyde intentionally sought solitary confinement, allowing him to leave the prison undetected. Clyde arrives disguised as a janitor at City Hall, where Mayor Henry is holding an emergency meeting, and passes through security. Nick and Dunnigan fail to find Clyde, but they discover a suitcase bomb loaded with
napalm planted in the room below the meeting. When Clyde returns to his cell and finds Nick waiting for him, Clyde tries to make another deal, but Nick refuses, having finally learned his lesson. Nick unsuccessfully urges Clyde not to activate the bomb before leaving, but he hears the detonator beeping and discovers the bomb hidden underneath his bed. Clyde briefly smiles and sits down, holding and looking at his daughter's handmade bracelet as the bomb explodes. Nick, officially the District Attorney, joins his wife Kelly at Denise's cello recital, having previously failed to do so. ==Cast==
