Catlow plot
"The Mexican cavalry wanted him murdered. The Apache nation wanted him massacred. Texas ranchers wanted him mangled and his only hope was a Marshal, who wanted him hanged."
Assassin Miller and Marshal Cowan hunt for the outlaw Catlow. During the American Civil War, Cowan and the ever-smiling Catlow were comrades, and Catlow helps Cowan when an Apache arrow hits him in the right leg, despite Cowan chasing him. Catlow manages to escape and he and his gang then rob a Mexican gold transport worth $2,000,000. Catlow flees with the stolen gold through dangerous territory for the Apaches, who, alongside Miller, Cowan and the Mexican cavalry, are hunting him and his gang.
