Barney Ross, Lee Christmas, Yin Yang, Gunner Jensen, Toll Road and Hale Caesar -- with newest members Billy the Kid and Maggie aboard -- are reunited when Mr. Church enlists the Expendables to take on a seemingly simple job. The task looks like an easy paycheck for Barney and his band of old-school mercenaries. But when things go wrong and one of their own is viciously killed, the Expendables are compelled to seek revenge in hostile territory where the odds are stacked against them. Hell-bent on payback, the crew cuts a swath of destruction through opposing forces, wreaking havoc and shutting down an unexpected threat in the nick of time - five tons of weapons-grade plutonium, far more than enough to change the balance of power in the world. But that's nothing compared to the justice they serve against the villainous adversary who savagely murdered their brother.

Rated R by the Motion Picture Association of America for strong bloody violence throughout.
