After the Civil War, ex-Union Colonel John Henry Thomas and ex-Confederate Colonel James Langdon are leading two disparate groups of people through strife-torn Mexico. John Henry and company are bringing horses to the unpopular Mexican government for $35 a head while Langdon is leading a contingent of displaced southerners, who are looking for a new life in Mexico after losing their property to carpetbaggers. The two men are eventually forced to mend their differences in order to fight off both bandits and revolutionaries, as they try to lead their friends and kin to safety.
