John Ferguson, a whistleblower at Denning, a major pharmaceutical company, becomes disillusioned with the perceived lack of action taken against the company, murders several executives, and commits suicide as the police enter the building. Tom Miller, a paralegal assigned to the Denning case, subsequently loses confidence in the scheduled trial against Denning, as Ferguson was their star witness. Miller's boss criticizes his idealism as financially unsound, and when Miller writes an unsolicited memo on an unrelated case on the Gambizzi crime family, Alan Emmerich, one the partners at the law firm, fires him. Roger, Miller's friend and a fellow paralegal, initially commiserates with Miller, but returns to the office in order to work late. Emmerich sends everyone else, including Miller's girlfriend, Anna, home early due to a technical problem with the firm's Internet access.
As Miller leaves the building, he sees a man in a suit set down a briefcase. A different man then picks up the suitcase and enters an elevator. Curious, Miller follows the man with the briefcase, only to see him produce a pistol from the briefcase and murder Janine, a lawyer. Panicked, Miller hides from the killer in the bathroom, where he discovers the body of a security guard. When he alerts Roger to the danger, Roger objects to Miller's plan to save Emmerich, as Roger does not believe that Emmerich would do the same for them. Regardless, Miller instructs Roger to contact the authorities as he tries to find Emmerich. Before Roger can make the call, the killer finds and strangles him. As Miller's recharging cell phone chimes, the killer realizes that there are more people left in the building than he anticipated.
Miller uses his knowledge of the building's security to evade capture and eventually discovers Emmerich in an office with a woman who Emmerich identifies as Lorraine Gambizzi. When the killer breaks into the room, Gambizzi grabs a pistol, but the killer is able to shoot her first. Not noticing Miller, who hides, the killer spares Emmerich's life and orders him to stay in the office. When the killer leaves, Miller surmises that the killer is a Gambizzi hitman sent to kill Lorraine, who was going to testify against her husband. With her death, Miller hopes the killer will leave. However, the killer attempts to gain entry into the record room, a reinforced vault that Miller and Emmerich use as a safe room. Using Miller's recharged cell phone, the killer draws Anna back to the building and taunts Miller with this fact.
The killer takes Anna hostage as soon as she arrives. Drawn out of the vault, Miller attempts to trade his access card for Anna's life, but the killer reneges on the deal, wounding Emmerich as he shoots at them. Now with access to the records, the killer starts a fire, only to realize that Miller tricked him into accepting a fake access card. Locked in the vault as the records burn, he chokes and falls unconscious. Miller enters the room to extinguish the fire, after which he realizes that the killer has recovered. As the killer beats Miller, Anna knocks him out with a fire extinguisher. Emmerich recovers the killer's pistol and kills him with it. Before he dies, the killer whispers a code to Miller.
Curious about the killer's last words, Miller investigates further and discovers that Denning likely targeted Roger for assassination because of his own whistleblowing about how the law firm was intending to throw the Denning case. When he confronts Emmerich, Emmerich begs him to destroy the evidence, as Emmerich believes the pharmaceutical company to be more powerful and ruthless than any crime family. When Miller refuses, Emmerich commits suicide. As Miller and Anna leave the building, the killer's earlier accomplice, now revealed to be a police officer, alerts his superiors, and a hitman outside the building radios that he has visual confirmation of Miller.JJ Feild as Killer
