Plot

When his mentor is taken captive by a disgraced Arab sheik, a killer-for-hire is forced into action. His mission: kill three members of Britain's elite Special Air Service responsible for his son's deaths.

Loosely-based on a true story, Killer Elite pits two of the world's most elite operatives--Danny, a ruthless killer-for-hire (Jason Statham); and Hunter, his longtime mentor (Robert De Niro)--against the cunning leader of a secret society of former Special Air Service operatives(Clive Owen). Covering the globe from Australia to Paris, London, and the Middle East, Danny and Hunter are plunged into a highly-dangerous game of revenge and deception--where things are not always what they appear to be.—Anonymous

In 1980, assassins Danny Bryce (Jason Statham), Hunter (Robert De Niro), Davies (Dominic Purcell), and Meier (Aden Young) are in Mexico to assassinate a man. Danny unwittingly kills him in front of his young child, then is injured during the getaway. Affected by this outcome, Danny retires and returns to his native Australia. One year later, Danny is summoned to Oman where Hunter is being held captive. He meets with the Agent (Adewale Akinnuoye-Agbaje), who arranges missions for killers, and learns that Hunter accepted a $6 million job but failed to accomplish it. If Danny doesn't complete Hunter's mission, Hunter will be executed.

Danny is introduced to Sheikh Amr, a deposed king of a small region of Oman who wants Danny to kill three former SAS agents-Steven Harris (Lachy Hulme), Steven Cregg, and Simon McCann-for killing his three eldest sons during the Dhofar Rebellion. Danny must videotape their confessions and make their deaths look like accidents, and he must do it before the terminally ill Sheikh dies. This will allow the Sheikh's fourth son, Bakhait (Firass Dirani), to regain control of the desert region his father had ruled. If Danny fails, Hunter will be killed. Danny reunites with Davies and Meier. They agree to help him in exchange for a share of the money.

As Danny and Meier sneak into the house of their first target, Steven Harris, in Oman, Davies questions local bar patrons about former SAS members. This is reported to the Feathermen, a secret society of former operatives protecting their own. Their head enforcer, Spike Logan (Clive Owen), is sent to investigate. Logan sends one of his boys to trail Davies who takes pics of Danny, Davies & Meier. Danny spots him, but Logan's man escapes.

After Harris has confessed on videotape, Danny and Meier take him to the bathroom. Their plan is to break his neck using a hammer with tiles similar to those of the bathroom floor to make it appear that Harris slipped and broke his neck. Danny is distracted by the arrival of Harris's girlfriend and when he returns to the bathroom, he finds that Meier was forced to kill Harris hastily in a struggle.

Back in London, Davies discovers the second target, Steven Cregg, preparing for a long nighttime march in wintry weather at a local SAS base. Davies pretends to be a civilian having car problems outside the base's fence, allowing Danny to infiltrate the base. There he drugs Cregg's coffee to induce shock and cause Cregg to die of hypothermia during the march. Danny, in uniform, follows Cregg on the march, and a delirious Cregg confesses on videotape to Danny before he dies. Logan almost catches Danny after identifying him from the surveillance photos, but Danny escapes.

Danny traces Logan & tells the Agent that his team is being followed by Logan. The Agent is in touch with the British Govt, who seems to be driving this entire operation to manipulate the Sheik for his oil somehow. The British intelligence offers to take care of Logan. The British make contact with Logan's superiors who were in favor of leaving the Oman story & all associated men alone in the first place.

Going to their last target, Simon McCann, currently a mercenary, they rig a truck to respond to remote control with the help of a new and inexperienced team member, Jake (Michael Dorman). As McCann is on his way to a fake job interview, Meier and Jake take control of the truck from another car and cause it to move in front of McCann's car, killing him. However, Logan and his men were watching over McCann. A gun fight in the docks ensues, and Meier is accidentally killed by Jake due to his lack of experience. Danny and Davies decide that the case is over, and they part ways. Davies is soon hit by a truck and killed while being chased by Logan's men.

Danny returns to Oman and gives the Sheikh the last taped confession, which he has faked. Hunter is released and returns to his family, while Danny heads back to Australia and reunites with Anne (Yvonne Strahovski), a childhood acquaintance. Soon, he is informed by the Agent that there is one last man who participated in the Sheikh's sons' murders and that this man, Ranulph Fiennes, is about to release a book about his experiences as a member of the SAS.

Danny tells Anne to go to France with Hunter to protect her while he carries out the last job. The Sheikh's son confirms that Harris was an innocent man. Logan, meanwhile, traces Danny through the Agent and sends a team to protect the author, but Jake distracts them, allowing Danny to infiltrate the building and shoot the author. He chooses to only wound the author, however, but takes pictures that appear to show him dead. Logan chases and captures Danny, taking him to an abandoned warehouse, but he is interrupted when the agent from the British government arrives and reveals that the British government is behind the events because of the Sheikh's valuable oil reserves. A three-way battle ensues, with Danny escaping and Logan shooting the government agent.

Danny and Hunter head to Oman to give the Sheikh the pictures. However, Logan arrives first and confronts the Sheikh, telling him that the pictures are fake and then stabbing him to death. The Sheikh's son does not care and gives the money, which was intended for Danny and Hunter, to Logan. Hunter spots Logan leaving, and they chase after him, along with the Sheikh's men.

After stopping the Sheikh's men, Danny and Hunter confront Logan on a desert road. Danny says that Logan can keep the money (though Hunter takes some of the money for his expenses and his family). They give Logan the remainder, telling him that he'll need it to start a new life away from the government after killing the government agent and acting against the wishes of the Feathermen and the British government. Danny says that it's over for him and that Logan must make up his own mind. They leave him there, saying they'll send a cab for him from the airport. Danny meets with Anne in France to start a new life.
