"Don't set them up if you can't take them down!" Times may have changed since the days of the Old West, but in the war-torn South American state of San Diablo, the law of the gun still holds sway. When former hero-for-hire Maria Vasquez, alias Tarantula, finds herself wanted for murder south of the border, Texas Rangers Division lawman "Tex" Dawson is assigned to bring her in. But they're on a collision course with the outlaw Black Riders biker gang, who plan to make sure she never makes it to trial alive. COLLECTING: Six Guns 1-5
