Wanderers of the West

In Montana, a gang of rustlers led by Jack Benson steals a herd of horses belonging to the Mallorys. While escaping, Benson's young comrade, Waco Dean, who goes by the name Rusty Mack, fatally shoots Mallory. After being unable to trace the rustlers locally, Mallory's son Tom travels across the Western states to Arizona to find his father's killer. Waco, meanwhile, has taken up residence in Arizona with his sisters, Laura Lee and Sugar, at the family ranch, where he works as the foreman. Waco is surprised when Benson and his confederate, Bronco, arrive in his town. Benson warns Waco that Tom is after him, then pressures him to join the gang. Waco resists Benson's offer, and while walking into town, bumps into Tom. Neither man recognizes the other, and Tom, who uses the pseudonym "Arizona," befriends Waco, who thinks that he is the notorious "Arizona Kid." When Tom says he is looking for fellow outlaw "Rusty," Waco promises to introduce him when he knows Tom better. Waco brings Tom into Benson's gang, and to prove his loyalty, Tom steals a herd of cattle. Tom, however, insists that he is a drifter and immediately leaves the outfit, only to be taken at gunpoint by Waco's little sister Sugar. After deciding for herself that Tom is not a rustler, Sugar takes him to meet Laura, whom he once knew in Montana. Laura promises not to reveal his real identity. Tom later tells Waco that they rustled his own herd, but Waco explains that the ranch's income comes from the government, which pays for them to keep a herd of buffalo. Benson discovers the buffalo and hatches a plan to steal the herd, and drive them to Mexico, where he will cross-breed them with cattle to create a new beef stock. The next morning, Tom insists on stealing back Laura's herd, but Laura and her ranch hands believe he is a rustler and attempt to capture him. Tom escapes and confronts Benson, but Bronco knocks him out. Benson keeps Tom hostage, planning to kill him and blame him for the stolen buffalo. However, Sugar finds Tom and frees him after he promises to buy her a new pair of boots. Having learned from Benson that Waco is "Rusty," Tom returns to the ranch. Waco, meanwhile, has learned Tom's true identity from Laura, and shoots at Tom as soon as he rides up to the ranch. After Tom convinces Waco to lay down his weapons to save the buffalo, Tom, Waco and Laura ride out to together to protect the herd, while Sugar rounds up the local ranchers. Tom chases Benson and his gang into the hills while the ranchers round up the buffalo, and the gang surrenders after Benson is shot. Waco is mortally wounded during the gunfight. Before he dies, he apologizes to Tom for killing his father, and asks Tom to look after his sisters. Later, Sugar admires her new boots and tells the cook, Slim, that Tom and Laura have sent for a preacher.
