Two ranch hands try to save the boss's son from a gambling debt.

Upon arriving in Arizona, out-of-work cowboys Kansas Jones and Chito Rafferty head for the nearest saloon to see if there are any jobs in the area. There they become embroiled in a fight between saloon owner Clint Burrows and Drusilla "Dusty" Willis. Dusty, a rancher, is furious at Burrows for allowing her weak-willed brother Harry to gamble in his saloon and strikes him with her riding crop. When Burrows begins to hit back, Kansas and Chito intercede on Dusty's behalf, and out of gratitude, Dusty offers the cowboys work on her ranch. Burrows, meanwhile, confronts Harry about his $3,000 gambling debt, demanding that he pay up with Dusty's cattle by the next morning. Although Dusty has ordered Kansas and Chito to help her brother in the south flat, Harry abandons the cowhands so that he can round up cattle for Burrows, who has arranged for Ringo Kid, a notorious rustler, and Trump Dixon, his own henchman, to take the herd. As Ringo, Trump and their men descend on the cattle, however, Kansas and Chito ride up and drive off the rustlers. Harry pretends to join in the fight against the rustlers and then feigns an injury, but when Dusty arrives on the scene, she detects his ruse and chastises him. In town, meanwhile, Ringo accuses Burrows of setting him up and demands his payment. When Burrows refuses to pay, Ringo robs his safe at gunpoint and takes a billfold full of money. Angry that he has been double-crossed, Burrows goes to confront Harry, who has decided to leave the ranch for good, and is about to shoot him when Chito and Kansas interrupt. After forcing Burrows off the ranch, Kansas convinces Harry to "come clean" with Dusty and return to the ranch. Impressed by Harry's honesty, Dusty offers to pay his gambling debt and then entrusts Chito and Kansas with the money. On the road to town, the cowboys spot Ringo on his horse and, recognizing him as a rustler, chase him. Chito finally corners Ringo among some rocks, but the rustler knocks him out and flees. Later, Kansas finds Burrows' billfold in the dirt and takes it with him to town. At the saloon, Kansas and Chito buy up Harry's IOUs, an exchange witnessed by Ringo. After the cowboys leave, Ringo sneaks into Burrows' office, steals the money again and kills Burrows. Kansas and Chito are accused of the crime, but when Sheriff Cole and his posse are about to arrest them, they escape. While Chito distracts the pursuing posse, Kansas rides to town to find Trump. At gunpoint, Kansas forces Trump to take him to Ringo's remote hideout, and there Kansas engages the rustlers in a gunfight. Chito, meanwhile, has been caught by the sheriff, but the trusting Dusty connives to free him. With Chito's help, Kansas defeats the rustlers and lassos Ringo. Kansas then shows the sheriff that Ringo was carrying the stolen money and thereby vindicates himself and Chito. Although Kansas and Chito then head for Prescott to testify against Ringo, Dusty is confident that they will return soon, as Kansas has deliberately left Chito's beloved "lucky peso" with Harry.
