The world's top bodyguard gets a new client, a hit man who must testify at the International Court of Justice. They must put their differences aside and work together to make it to the trial on time.
Barney (Stallone), Christmas (Statham) and the rest of the team comes face-to-face with Conrad Stonebanks (Gibson), who years ago co-founded The Expendables with Barney. Stonebanks subsequently became a ruthless arms trader and someone who Barney was forced to kill... or so he thought. Stonebanks, who eluded death once before, now is making it his mission to end The Expendables -- but Barney has other plans. Barney decides that he has to fight old blood with new blood, and brings in a new era of Expendables team members, recruiting individuals who are younger, faster and more tech-savvy.
