A female mine owner drives her workers so hard that they finally walk out. Furious, she hires a band of vicious gunfighters to keep the miners under control. Marshal Ragan is called in to set matters straight.
The marshals try to prevent war between striking miners and and out-of-town miners (protected by gunfighters) brought in by a mine employee scheming to take ownership from the current owner, the widow of the mine's founder.
