Silver prospector Larkin Moffatt tricks partner Charlie Storrs out of a rich assay, then escapes to Silver City where he sets up am assaying office. Three years later, Storrs arrives in town, married to Josephine, Moffatt's old flame. With his past uncovered, Moffatt is about to leave town. But Candance, who holds a silver claim leased from mine owner Jarboe, induces Moffatt to stay on as mine foreman. Jarboe has since learned how rich the claim is and he has assembled a band of cutthroats to prevent the ore's removal before the lease expires in 12 days.
