As the duo carries out a series of high-stakes hits, Steve proves to be a natural, albeit volatile, student. However, during their missions, Bishop discovers that Harry’s "betrayal" was actually a setup by Dean, the head of the agency, to cover up his own corruption. Bishop realizes he was manipulated into murdering his only friend. The Climax

Arthur Bishop is an elite "mechanic"—a hitman with a strict code and a talent for making his targets' deaths look like accidents or natural causes.

Steve drives away in Bishop’s vintage car, thinking he has won. However, he finds a note from Bishop: "Steve, if you're reading this, you're dead." Bishop, always two steps ahead, had rigged the car to explode. While Steve is consumed by the blast, Bishop—having faked his own death at the gas station—slips away to start a new life, proving he is still the master of the craft.

Driven by guilt and a sense of responsibility, Bishop takes Steve under his wing. He trains the younger man in the meticulous art of the "mechanic," teaching him: How to track a target without being seen.
