When dusty outlaw Clay Wilder pulls off the biggest and last heist of his storied career, he and his gang head south of the border to avoid the long arm of the law and the U.S. Army. They think themselves out of reach in the small town of Rio De Sangre, but Clay and his gang have only jumped out of the frying pan and into the fiery bowels of hell and all its evils. Shadowy creatures lead by an ancient Conquistador turned vampire, launch their quest to remake the Americas in their own dark image. With the help of Maria and a Priest, Clay must avoid the soldiers, defeat an army of grotesque undead, and rescue the gal to survive and recover his fortune. His only hope: A suicidal foray into Aztec tunnels wearing a suit of armor and riding a wagon filled with explosives. As the fuse burns down, so do his chances of making it out alive.
