Seasoned hitman Arthur Bishop (Jason Statham) sets out to avenge the brutal murder of his mentor, Harry (Donald Sutherland), and finds himself joined by Harry's vengeful son (Ben Foster), who is eager to follow in his late father's footsteps, in this remake of the 1972 action thriller starring Charles Bronson and Jan-Michael Vincent. Harry taught Arthur how to be a detached killer who always hits his mark. Now Harry is gone, and for the first time in Arthur's career it's about to get personal. As lone-wolf assassin Arthur prepares to hunt down Harry's killers, he is approached by his fallen mentor's vengeful son, Steve, who is eager to take up the lethal tools of his father's trade. Unadept at working with a partner yet compelled to help Steve carry on the family tradition, Arthur agrees to take him on as a protégé. Later, the duo begins to methodically eliminate their targets, forging a partnership born of blood with each new hit. The closer Arthur and Steve get to the name at the top of their list, however, the more apparent it becomes that his job will be anything but business as usual.
