Wells Fargo sends Johnny Macklin (
Johnny Mack Brown) to Rimrock to investigate stage hold-ups and general lawlessness which, according to local agent Tom Jamison (
Steve Clark) is caused by saloon owner Steve Corbin (
Tristram Coffin) and his henchmen Duke Sprague (
Marshall Reed) and Ace Jenkins (
Terry Frost). When Steve kills a man he had cheated in a poker game, the Rimrock Chronicle, owned by Idaho Jim Foster (
Raymond Hatton) and edited by his daughter, Diane (
Reno Browne), starts a vigilante movement to clean up the town. Jamison, also the mayor, swears Johnny in as the town marshal. Johnny lets henchman Slats Harper (
Lynton Brent) overhear information about a fictitious gold shipment, and traps some of Steve's men when they attempt a hold-up. Steve packs the jury and his men are set free. Saloon singer Kitty Malone (
Claudia Drake), who is in love with Steve, becomes jealous of Flo Vickerk (
Christine McIntyre), and warns Johnny that three gunmen have been imported to kill him. Flo tells Steve that Kitty is an informant, and Steve plans a double murder of Kitty and Johnny.
