Johnny Mack Brown's Universal western series was drawing to a close when Cheyenne Roundup was released in mid-1943. Brown is herein cast in a dual role, as honest Gils Brandon and his less-than-honest brother Buck. Pursued by lawman Steve Rawlins (Tex Ritter), Buck tries to pass himself off as the upright Gils.
