Logan Purcell (Morgan Woodward) and his band of raiders have been stealing anything and everything from the peaceful Indian settlements living on the Cimarron Strip. After coming to Marshal Crown (Stuart Whitman) for help, Willie Snake (Valentin de Vargas) is ruthlessly shot down by Purcell. Hot on their trail, Crown tracks down the raiders and engages in a heated exchange of gunfire. During the exchange, Purcell shoots Crown and then escapes. The marshal is later discovered by a young white woman named Heller (Tuesday Weld). As she helps nurse Crown back to health, she also begins to realise she is falling for him.
