Arthur Bishop (Jason Statham) is a ‘mechanic’ – an elite assassin with a strict code and unique talent for cleanly eliminating targets. It’s a job that requires professional perfection and total detachment, and Bishop is the best in the business. But when his mentor and close friend Harry (Donald Sutherland) is murdered, Bishop is anything but detached. His next assignment is self-imposed – he wants those responsible dead. His mission grows complicated when Harry’s son Steve (Ben Foster) approaches him with the same vengeful goal and a determination to learn Bishop’s trade.
