The world's deadliest assassin and New York's biggest screw-up are mistaken for each other at an Airbnb rental.

The bodyguard Michael Bryce continues his friendship with assassin Darius Kincaid as they try to save Darius' wife Sonia.

With his reputation in tatters after a painfully unsuccessful delivery of a distinguished Japanese client, former triple-A executive protection agent, Michael Bryce, two long years after the disgraceful incident, is now reduced to a mere second-class bodyguard for hire. Under those circumstances, Bryce would do anything to prove his worth once again, and as a result, it won't be long before he accepts an offer from Interpol to escort the renowned international assassin Darius Kincaid from Manchester to the Hague. The task seems simple: Bryce only needs to transport the contract killer from point A to point B, nevertheless, Kincaid, as the only one with the guts and enough hard evidence to testify against a tyrannical Belarusian dictator, is an obvious target, while the trip to the Netherlands is long and hazardous. Without a doubt, this a race against the clock as the mismatched duo will have to put aside their grudges, in a non-stop concerto for bullets.

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.
