There was a time in the American Wild West when the land just over the border from Texas was outside of the jurisdiction of the United States government, when the most notorious, ruthless outlaws in a violent land could find refuge--in a land known as Badman's Territory. Sheriff Mark Rowley (Randolph Scott) rides into this land in search of his younger brother, but before he leaves he will face off against the James Gang, the Dalton Brothers and other infamous gunslingers, as well enter the battle to annex this lawless land into the United States as the future state of Oklahoma.
