This is a remake of the 1972 Charles Bronson film of the same name.
Jason Statham is a contract killer Arthur Bishop. At the beginning of the film he takes out a Columbian drug lord by drowning him in his own swimming pool. After he gets back from Columbia he is paid for the job by his handler Harry McKenna (played by Donald Sutherland). Harry tells Bishop about his son Steve (played by Ben Foster). The next job Bishop gets from the agency is to kill Harry which surprises him. He double checks the order with the agency boss Dean (played by Tony Goldwyn. When it is confirmed, he kills Harry by making it look like Harry was carjacked.
At Harry's funeral he meets Harry's son Steve, who tells him that he is going out to kill the first carjacker he can find. Bishop follows him and stops Steve from killing someone who looks like a carjacker. The he takes Steve under his wing to train him how to be a contract killer. He even lets Steve observe when he makes a hit, where he strangles a guy. He gets Steve a small dog and uses him to bait the next target who likes men and little dogs. He instructs Steve to slip the target a "ruffie" knock-out pill so he can be killed easily, but Steve decides instead to strangle the guy as he saw Bishop do on the last hit. But the guy does not go down so easily. Steve does kill him eventually but it is a messy job.
Dean who is Bishop's boss is not happy with the way the kill was achieved and that Bishop used Steve to do the work. But Bishop does not care. The next job Bishop is given is to kill a corrupt evangelist, Andrew Vaughn (played by John McConnell). Bishop plans with Steve to inject him with adrenaline so as to have the death look like a heart attack. But while they are waiting for the chance to kill him, a doctor comes into the room and injects the preacher with Ketamine which would neutralize the adrenaline so they choke him to death instead.
Bishop figures out that Dean tricked him into killing Harry because Dean is corrupt and Harry had discovered this about Dean. Steve figures out it was Bishop that killed his father Harry. Steve tries to blow up the car at the gas station to kill Bishop, but Bishop escapes. Steve thinks he has won, but when he goes to Bishop's home to gloat, he drives Bishop's car which explodes killing him.
Best part of story, including ending:
The double-cross that each tries on the other ones is very interesting.
Best scene in story:
I like the way that Bishop executes the hit on the drug lord in Columbia and how he is so effective and calm in his escape remaining undetected.
Opinion about the main character:
Bishop is without any empathy for his victims. For him killing is a job and he shows no guilt or remorse at all for what he has done.
