Barney and the rest of the team come face-to-face with Conrad Stonebanks, who years ago co-founded the team with Barney. Stonebanks became a ruthless arms trader and someone who Barney was forced to kill, or so he thought. Stonebanks now is making it his mission to end the team, but Barney has other plans. Barney decides that he has to fight old blood with new blood, and brings in a new era of team members, recruiting individuals who are younger, faster, and more tech-savvy.
