Secret Service agent Mike Banning finds himself trapped inside the White House in the wake of a terrorist attack and works with national security to rescue the President from his kidnappers.

After the British Prime Minister has passed away under mysterious circumstances, all leaders of the Western world must attend his funeral. But what starts out as the most protected event on earth, turns into a deadly plot to kill the world's most powerful leaders and unleash a terrifying vision of the future. The President of the United States, his formidable secret service head and a British MI-6 agent who trusts no one are the only people that have any hope of stopping it.

In London for the Prime Minister's funeral, Mike Banning is caught up in a plot to assassinate all the attending world leaders.

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. The latest mission becomes a clash of classic old-school style versus high-tech expertise in the Expendables' most personal battle yet.
