A Classic Action Adventure of the Old West on Cimarron Strip. Left for dead by his gang of cutthroats after a daring robbery of a U.S. Army payroll, Bo (J.D. Cannon) returns eight and a half years later to claim his share of the theft. Using the papers of a Texas deputy he killed, he gets a job as a deputy with Marshal Crown (Stuart Whitman). The outlaw, unsuccessful in claiming his share of the loot, begins killing off his former partners, who have settled in the Cimarron Strip. His killings seem to be honestly defensive, but while out of town, Marshal Crown discovers a "wanted" poster for Bo. A quick return to Cimarron City now becomes a necessity for the marshal.
