Vier mannen rijden na de burgeroorlog door de Texaanse woestijn op zoek naar gestolen legerwapens. Ze worden voortdurend aangevallen door bandieten en Indianen. Ze zetten hun speurtocht verder, die hen naar een generaal met grote ambities leidt. De man wil mede dankzij het wapenarsenaal een nieuwe hoofdstad van de Zuidelijke staten opzetten en uiteraard ook leiden.
