The plot finds the team coming face to face with Conrad Stonebanks (Gibson), who years ago co-founded the Expendables with Barney (Sylvester Stallone). Stonebanks subsequently became a ruthless arms trader and someone Barney was forced to kill or so he thought. Stonebanks is now making it his mission to end the Expendables, but Barney brings in a new generation of team members who are younger, faster and more tech-savvy to take him down.
