Bandolero!

A pair of outlaw brothers on the run must fight off a sheriff's posse and vicious Mexican bandits. Dee Bishop and his gang rob a Texas bank but the sheriff captures them and throws them in jail. They're about to be hanged when Dee's older brother, Mace, comes to their rescue by posing as the executioner. The gunslingers grab Maria, a Mexican woman whose husband died in the robbery attempt, and head out of town -- fast. But they soon have Sheriff July Johnson and his posse hot on their trail. The thieves flee across the Mexican border with their protesting hostage. Soon, however, Maria has fallen for Dee and the two begin a romance. Eventually, the posse catches up with them, but the lawmen join forces with the outlaws to fight off attacking Mexican bandits in the film's violent climax. (official distributor synopsis)
