A Confederate deserter battles a Mexican bandit when the deserter's child dies for lack of milk. Warner (George Hilton) receives word his girlfriend is dying and about to give birth to the couple's child. The woman is the daughter of Don Pedro Sandoval (Ernest Borgnine), who hates all gringos and Warner in particular. Warner sets out for Juarez, but is captured by a Confederate unit and jailed. He escapes with two other men when they flee from their grave-digging detail. Warner arrives in Juarez where he finds his lover has died of cholera after having given birth to a baby boy. Sandoval gives the squalling, sickly infant to Warner, but the locals refuse to help Warner find milk for the baby. One callous rancher drops a bottle of milk rather than help the hated gringo. The baby dies, and Warner and his men join a group of outlaw monks led by the Padre (Leo Anchoriz). Warner seeks revenge on those who would not help his cause. Staying one step ahead of the cholera epidemic and the Confederates. Warner returns to the rancher who dropped the bottle and drowns him in a bucket of milk while the townsfolk watch in horror. The gang continues to rob and pillage, taking refuge in a bar and pawing at the saloon girls. Warner then sets his sights on Sandoval. He tracks the bandit to a bull ring where the two fight with knives for the inevitable showdown. The film is plagued by poor English dubbing.
