The epic story of a family involved in the Oklahoma Land Rush of April 22, 1889.

Young Englishman inherits ranch which he wants to sell, but Gene's gonna turn him into a real westerner instead. When new owner Spud arrives from England, Autry convinces him not to sell the ranch but to raise horses for the Army. When both Autry's and Neale's bids are the same, the Colonel calls for a race to decide the winner. But that night Neale has Autry's stable burned.

Ranch owner Sandra, fresh from animal husbandry school, brings a flock of sheep into cattle country. The local ranchers don't like it, and ranch foreman Gene must deal with it.

Crash Corrigan, a recent graduate of Annapolis, and Diana, a go-getting reporter, join Professor Norton for a search for the source of a string of earthquakes, Atlantis. They ride Prof. Norton's rocket submarine searching the sea and little Billy Norton, the professor's son stows away, of course. When they find Atlantis they are caught in a war between peaceful Atlanteans, note their white capes, and war-monging Atlanteans, note their black capes. After many harrowing moments for Crash, Diana, Prof. Norton and Billy, they barely get away with their lives when they escape a tower of Atlantis raised to the surface for the sole purpose of dominating or destroying the Earth (Which one depends on the compliance of the upper world dwellers.)

Gene and Frog, out to stop a bunch of cattle rustlers, assume the identities of what they believe to be dead bandits, which soon gets them in big trouble.

Autry and his buddies have a horse selling business which is threatened by a tractor company which claims horses are out of date.

Gene is on to Scanlon and tries to get him to buy back the deeds by salting the mine with gold. But when a new vein is really discovered Gene has to stop the sales but is trapped in the mine by Scanlon's men.

A wrongfully-imprisoned man becomes determined to find who was responsible for the death of a local sheriff.

The old west range war story transported to Georgia, with Autry as the hero.
