Bill Hollister organizes a wagon train to break the unfair monopoly held by Jake Lynch on food prices in the mining camps. The Rambler joins the train when it leaves for Gold Hill, and takes command when Hollister is killed from ambush. Jacques Frazelle, formerly Hollister's second-in-command, schemes to get rid of The Rambler and win Sue Smith. He plots with Lynch to disrupt the train, but The Rambler beats him in a whip-fight.
