The Nebraskan (1953)

When his Indian assistant, Wingfoot (Maurice Jara), is accused of murdering a Sioux chief, Army scout Wade Harper (Phil Carey) brings him to Fort Kearney, Neb., where Colonel Markham (Regis Toomey) insists the young man has the right to a fair trial rather than handing him over to the Sioux. While in jail, Wingfoot is forced to escape with ruthless prisoner Reno Benton (Lee Van Cleef). Wade sets out with a small party to rescue his friend, with the Sioux right behind him.
