One night in 1885, Masked raiders led by Sam Hollis attack the "K" Ranch, where owner Wade Kingsley and partner Slim Mosley bravely defend their property after Matilda Kingsley and infant son Wade Jr. safely return east to
New York, her hometown. Wade and Slim are murdered, but vow before they die that their sons someday will avenge them. 25 years later in 1910, the wealthy Matilda receives a visit from her niece Carol and cowboy Slim Mosley Jr., who has come to New York City to compete in a rodeo. They intend to use Slim's earnings to buy a prized bull called Cuddles and take him back west to replenish the K Ranch's stock. Sweet but inept Wade Jr. has always wanted to be a cowboy. He goes to the rodeo, where his bungling interference costs Slim first prize. To make amends, Wade buys the bull for Slim and accompanies them back west by train. After a while, Slim warms to Wade and agrees to become partners, like their dads. Out west, to keep townsfolk from mocking the tenderfoot, Slim decides to introduce Wade to one and all as "Killer Jones," a tough hombre. Due to his heroic actions in stopping a runaway stagecoach, with Slim performing the actual heroics, Wade ends up being elected sheriff, impressing dance hall girl Dolly Riley. Ranch hand Pete Rio is secretly working with banker Dan Hollis, who is every bit as corrupt as his father was. Dan's got his eyes on the K Ranch so he can sell the land to the government, which wants to build a dam. Dan tries proposing marriage to Carol, but she rejects him, so he announces that the bank will begin foreclosure proceedings against the ranch. In disguise, Wade infiltrates the gang of masked raiders. He is caught and bound to a chair, strapped to sticks of dynamite, and when Slim comes to his rescue, Dan Hollis knocks him cold. All seems lost until the boys manage a last-second escape. Dan is dealt with accordingly, after which the pardners and their romantic partners celebrate their success. ==Cast==
