 Doctor Gene Autry (Gene Autry) returns as a "doctor on horseback" to the frontier town in Utah where his father was killed and finds a feud raging between mine owner Jayda McQueen (Onslow Stevens) and cattleman Bowie French (Denver Pyle). Gene s only friend in town is "Dusty" Cosgrove (Pat Buttram). Gene answers a summons by Karen McQueen (Elaine Riley) to treat her younger brother (Teddy Infuhr), but the boy unexpectedly dies and McQueen comes gunning for Gene, who is saved by French s timely intervention. When one of French s gunmen is shot down by a miner, the ranch hands attack the mine and Gene aids the McQueen forces.
