John Wayne plays Taw Jackson, a range-hardened rancher who's hell-bent on capturing the infamous WAR WAGON, an ironclad stagecoach protected by a small army of men and owned by a thieving cattle baron who robbed Taw of his gold and good name years before. To get even, Jackson recruits Lomax (Douglas), a brash gunslinger, and a raucous crew of misfits and readies them to pull off one of the most impossible heists of all time.
