A CIA operative hires a team of mercenaries to eliminate a Latin dictator and a renegade CIA agent. Barney Ross leads the "Expendables", a band of highly skilled mercenaries including knife enthusiast Lee Christmas, martial arts expert Yin Yang, heavy weapons specialist Hale Caesar, demolitionist Toll Road and loose-cannon sniper Gunner Jensen.
Mr. Church reunites the Expendables for what should be an easy paycheck, but when one of their men is murdered on the job, their quest for revenge puts them deep in enemy territory and up against an unexpected threat.
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.
