Having masterminded the hold up of his company office, a mining engineer is barred from the industry. He then sets up shop as an assayer, scheming to acquire a rich silver mine lease from its operators.

Ann and Tom Howard arrive from the east to take up ranching. But Tom wants to return and forges his sister's name to the deed and sells it to Larson. Eddie knows there is silver ore in the area and that Lawson, who killed the Sheriff, is out to get all the ranches. When Lawson appoints himself the new Sheriff, Eddie organizes the ranchers to fight Lawson and his men.

Sintown is just a deserted ghost town until Vanerpool starts looking for silver. Cookie and Roy's partners put $20,000 into the business only to find that the mine is worthless and Vanerpool is bankrupt. Carol comes out to look for silver to save the company, but does not know that their engineer, named Regan, is crooked and wants all the silver for himself. But only Old Ed knows where the mother lode is located.

A mining engineer teams up with a crusty deputy sheriff to solve the mystery killings at an old mine where the owner's family waits for him to die, and where a valuable radium strike may have been made.

Unjustly booted out of the cavalry, Mike McComb strikes out for Nevada, and deciding never to be used again, ruthlessly works his way up to becoming one of the most powerful silver magnates in the west. His empire begins to fall apart as the other mining combines rise against him and his stubbornness loses him the support of his wife and old friends.

Not quite a western, not quite a historical drama, Under Strange Flags is a little bit of both, and a lot of former RKO Radio cowboy hero Tom Keene. The star is cast as Tom Kenyon, a roving adventurer in Mexico during the Revolution. Hoping to protect the silver mine owned by heroine Dolores De Vargas (Luana Walters), Tom receives unexpected assistance from none other than rebel leader Pancho Villa (Maurice Black).

Blind Pete Horne knows the location of the Lost Spanish Silver Lode, but is knifed before he can tell anyone. His seeing eye dog, Duke, brings Rex Allen and Gabriel Horne to Pete's lifeless body. They set out to find the killer and run into trouble near Silver City, Arizona, when they rescue Katie McIntosh from a gang that is chasing her buckboard.

A lawman goes undercover in order to capture the outlaws who murdered his wife.

Donald Barry, not yet Donald "Red" Barry, heads the cast of the Republic western Ghost Valley Raiders. A federal marshal, Barry is assigned to put an end to the activities of a stagecoach-robbery gang. That's why he spends most of the film pretending to be an outlaw himself. Stunt specialist Yakima Canutt plays a secondary villain, and also doubles for Barry in the dicier action scenes.
