Arthur Bishop is the main protagonist of the film The Mechanic and it's sequel Mechanic: Resurrection. He is a professional assassin who specializes in making his hits look like accidents, suicides or the acts of petty criminals. He is portrayed by Jason Statham.
Arthur Bishop works as a contract killer. He sneaks into the lavish home of a Colombian Drug Cartel leader and discreetly drowns him in his own pool. He later visits his friend and his contractor Harry Mckenna who pays him money. Bishop finds that his new assignment is to kill Harry. Bishop's employer confirms by phone that the contract is correct, whereupon Bishop requests a face-to-face meeting with the contractor Dean. Dean tells Arthur that Harry betrayed his agency. Bishop kills Harry reluctantly with his own gun and making it look like a carjacking. At Harry's funeral Bishop meets Harry's son Steve. As Steve is reckless and wanted vengeance Bishop decided to train his as a mechanic. After some struggle Bishop trained Steve as a successful assassin.
Bishop's latest contract is to kill Andrew Vaughn, the leader of a cult-like church. Bishop and Steve successfully kill him by suffocating him, but are discovered and forced into a shootout with the guards. They slip out while the building is being evacuated and fly home separately. At the airport, Bishop sees a supposed victim of the mission that Harry allegedly sold out. Bishop realizes that Dean had tricked him into killing Harry, and that Dean engineered the failed mission to cover up his own shady dealings. Later Bishop is ambushed by some assassins and he kills them and saves Steve who was also ambushed.
Bishop told Steve to collect supply from Bishop's house to kill Dean where Steve finds his father's gun and comes to know that Bishop killed him. Later Bishop and Steve kill Dean. Then Steve takes Bishop to a petrol station for filling gas. Steve floods the floor with petrol and shoots the car with Arthur inside it. Steve returns to Bishop's house and performs two actions that Bishop told him not to do: playing a record on the turntable, and taking the 1966 Jaguar E-Type Bishop had been working on. As he is driving away, Steve notices a note on the passenger seat: "Steve, if you're reading this, then you're dead!" and he laughs at it thinking it was a joke. Moments later, the car explodes, killing him and Bishop's house also explodes at the moment. It is later revealed that Arthur escaped underneath the truck before Steve blows it up, indicting that Steve failed to kill Bishop and gets into another truck by the beach and drives away.
After faking his death, Arthur Bishop has been living quietly in Rio de Janeirowith the name Santos. He is approached by a woman, Renee Tran, who states that her employer wishes for Bishop to kill three targets and stage them as accidents. Bishop takes a picture of her and fights off her mercenaries before escaping. Bishop goes to Thailand and takes shelter at the beach house of his friend, Mae. He investigates the woman and learns that her employer is a man named Riah Crain.
An attractive young woman named Gina Thorne arrives at the shore and, when she asks Mae for some first aid items, Mae notices a split lip and bruising on her arm that suggest she is being treated badly. That evening, Mae notices the young woman being attacked in her boat and convinces Bishop to go out to help. He boards the boat, but his attempts to warn off the man go unheeded and in the ensuing altercation the man falls, hits his head on a piece of the boat's equipment and is killed. Mae arrives, to take Gina to shore, and Bishop quickly explores the ship for clues before setting fire to it to cover his tracks. Bishop learns that the young lady is called Gina, and is working for Crain and confronts her, who reveals that she was working in a children's shelter in Cambodia and Crain threatened those children and forced her to arrive at Bishop’s location. Bishop deduces that Crain’s plan was to make him fall for her before she is kidnapped and thus Bishop will be forced to accept the mission. Later, Bishop notices Crain’s operatives watching him and gets intimate with Thorne. He reveals to her that he and Crain were sold to a gangster when they were orphan children. They were trained as warriors until Bishop escaped. Bishop and Thorne end up having sex before they are both abducted the next morning. Bishop is brought to Crain, who gives the identities of the three targets.
The first target of Bishop is a warlord named Krill, who is incarcerated in a Malaysian prison. Bishop travels to Malaysia and gets himself imprisoned to access Krill. Bishop gains Krill’s trust by killing a man already planning on killing Krill. Bishop meets with Krill and kills him and Bishop escapes the prison with the help of Crain's operatives.
Bishop is informed that he only has 36 hours to kill the next target, Adrian Cook, who runs an underage trafficking ring in Sydney, Australia. Cook goes for a swim in his glass pool outside his high-rise apartment. Bishop breaks the glass, causing the water to spill out with Cook plummeting to his death. Once again, Bishop makes a clean getaway.
Bishop finds the boat where Thorne is held and attempts to save her, but fails. He is informed that he has 24 hours to kill the last target, Max Adams, who is an arms dealer in Bulgaria. Adams and Bishop decide to work together against Crain. Bishop fakes Adams’ death and tells Crain that the job is done. They arrange a meeting; but Crain is revealed to be planning to have Bishop killed.
Bishop kills Crain’s men before heading toward Crain's boat, where he fights more mercenaries before getting to Crain. Bishop finds Thorne, and they discover that Crain has the boat rigged to explode. Bishop puts Thorne in an underwater escape chamber pod to let her escape and goes to find Crain and defeats him in hand to hand combat. Bishop leaves Crain chained with an anchor chain to the boat and escapes moments before the boat explodes, killing Crain. Thorne is told that there have been no survivors.
When Thorne returns to Cambodia to continue her work, Bishop shows up.
In the last scene, Adams reviewing security footage, which shows Bishop escaping in another escape chamber from Crain's boat. Adams deletes the video to fake Bishop's death once more.
