+ Barney augments his team with new blood for a personal battle: to take down Conrad Stonebanks, the Expendables co-founder and notorious arms trader who is hell bent on wiping out Barney and every single one of his associates.
+ The Expendables-led by Barney Ross and formed by Lee Christmas, Gunnar Jensen, and Toll Road-extract former member Doctor Death, a knives specialist and team medic, from a military prison during his transfer on a train.
+ They recruit Doc to assist them in intercepting a shipment of bombs meant to be delivered to a warlord in Somalia. Arriving there, they reunite with Hale Caesar, who directs them to the drop point, where Ross is surprised to find out that the arms trader providing the bombs is Conrad Stonebanks, a former co-founder of the Expendables who went rogue and was presumed dead.
In the ensuing firefight, The Expendables manage to kill all but Stonebanks, who shoots Caesar twice. As the team attempts to aid him, they are forced to retreat due to Stonebanks' advanced weaponry, and Caesar is severely injured in the process.
