At a county rodeo, ace bronco rider Tom Larkin bets shifty cowboy Tate that he can ride the notorious horse Widowmaker. Although Tate tricks Tom's slow-witted friend Gaby Bush into spreading cockleberry juice on the already skittish horse, Tom rides Widowmaker and wins the bet. When Tom discovers that Tate talked pretty Hope Winters into betting her and her father's entire savings against him, he asks Gaby to give Hope his winnings. Before Gaby delivers the cash, however, Tate picks his pocket and takes off on his horse. Furious, Tom trails Tate, who shoots and kills Tom's horse and strands Tom in the brush. Eventually Tom meets up with Denver Ed, a vicious killer who, unknown to Tom, is wanted for the murder of Tate. The saddleless Denver offers to play the horseless Tom a hand of poker, but when Tom discovers that Denver is cheating, he overpowers the killer and takes his horse and gun. Tom rides to Micaville, where he is spotted by Mark Hollister, an assayer who has befriended Hope as part of a plot to take over her father's mine, which only he knows is rich with minerals. Based on information from Denver's "wanted" poster, Hollister assumes that Tom is the killer and offers him $500 to kill Hope's father. Tom takes the money and rides to warn Hope about Hollister, but is shot at by her suspicious father. Tom then returns to Micaville to warn Gaby, who is working in Hollister's assay office on a formula for acid-made gold, to get out before he is caught with Hollister. Sure that the acid-stained money that Hollister gave him will implicate him, Tom confronts the assayer and, with Gaby's help, holds him at gunpoint. After Tom leaves to find the sheriff, Denver, who has been hiding in Hollister's back room, overpowers Gaby and, at Hollister's command, shoots at Hope's father through the office window. As Tom rushes back to accuse Hollister and Denver, one of Gaby's back-room gold concoctions explodes. In the ensuing confusion, Denver escapes but is chased and tied up by Tom, who then rides to rescue Hope from Hollister. After a fierce pursuit, Tom defeats Hollister and is rewarded with a passionate kiss from Hope.
