The Mechanic 3 (2025) is a gritty action thriller starring Jason Statham as Arthur Bishop, a highly skilled and methodical contract killer known as a “mechanic” — someone who eliminates targets with precision and subtlety, making the deaths look like accidents or natural causes. Bishop lives by a strict personal code and remains emotionally detached from his work, taking pride in his clean, efficient hits.

The story takes a sharp turn when Bishop is assigned to kill his mentor and close friend, Harry McKenna (played by Donald Sutherland), who is accused of betraying the organization they both work for. Though conflicted, Bishop completes the job under false pretenses. Feeling guilt, he decides to look after Harry’s son, Steve McKenna (Ben Foster), a troubled young man unaware of Bishop’s role in his father’s death.

Bishop begins to train Steve in the art of assassination, teaching him the discipline and detachment required for the job. However, Steve’s impulsive and emotional nature contrasts with Bishop’s cold precision, creating tension between the two. As they work together, secrets begin to surface, and their mentor-student relationship is put to the test.

Eventually, Bishop discovers that the mission to kill Harry was a setup — Harry wasn’t a traitor, but a victim of corporate betrayal. Fueled by vengeance and a sense of justice, Bishop and Steve turn against the organization that manipulated them. The film builds to a climactic showdown, filled with twists, betrayal, and explosive action, highlighting themes of loyalty, revenge, and the price of living in a violent world.
