If anyone knows the road to purgatory, it’s Red Ryan. As a stagecoach guard, he’s faced holdups, ambushes, and all-out attacks from every kill-crazy outlaw, Indian, and prairie rat. But even he’s a bit reluctant to take on his next job: riding shotgun with his driver Buttons Muldoon on a stage bound from Fort Concho, Texas, to Fort Bliss. Word has it, the Apaches are on the warpath. They’re being led by a vicious war chief who means business, as in slaughtering every Texan from here to El Paso.
