Arthur Bishop is a skilled hitman with a very particular ethic: he only accepts jobs he considers "clean" and that require his exceptional ability to create deaths that appear to be accidents. His life, marked by secrecy and solitude, takes an unexpected turn when his mentor and father figure, Harry, is betrayed and murdered. With a mix of vengeance and pain, Bishop embarks on a mission to settle the score and discovers that familial ties, though complex, can become a driving force for unexpected impulses and decisions.
Enter Steve, an impulsive and somewhat troubled young man seeking to become as skilled an assassin as his adoptive father. Bishop agrees to train him, but as he does so, he becomes caught in an emotional whirlwind. Amidst this and his attempt to fulfill his revenge, the line between mentor and protégé begins to blur. As both confront their own morality and the dangerous world they inhabit, the plot intensifies. With spectacular action scenes and unexpected twists, the story evolves into a deadly game of wit and strategy. The relationship between Bishop and Steve transforms into a cat-and-mouse game, testing not only their loyalty but also their ability to survive in a world where no one can be trusted. The tension escalates, leading the viewer to question whether the true danger lies not in others, but within oneself.
