Former rancher Taw Jackson returns to his hometown to settle a score with corrupt businessman Frank Pierce; three years earlier, Pierce had Jackson wrongfully imprisoned and appropriated his land, including his house and some recently discovered gold deposits. Jackson plans to steal an upcoming $500,000 shipment of gold dust from Pierce's "war wagon", an armored stagecoach surrounded by mounted guards. Wes Fletcher, an elderly wagon driver employed by Pierce to transport dry goods, becomes Jackson's informant. The third member Jackson recruits for his team is Lomax, a gunslinger and safecracker, who earlier shot Jackson as part of Pierce's plot.
The fourth team member is Levi Walking Bear, a Kiowa translator, whom Jackson and Lomax rescue from a gang of Mexican bandits. Jackson then sends Lomax to pick up the final member, Billy Hyatt, a teenage drunkard and explosives expert. When the team first meets to discuss their plan, Fletcher brings his teenage "wife" Kate along, and flies into a jealous rage when Hyatt gives her some coffee.
Jackson and Levi negotiate with the Kiowas; because Pierce is deliberately starving the tribe off of their land, they agree to help. Meanwhile, Lomax rides into town and is approached in a saloon by Pierce, who offers him $12,000 to kill Jackson. An inebriated Hyatt enters, and comes dangerously close to revealing the plan. Lomax knocks him unconscious and hands him over to the Sheriff for the night, then accepts Pierce's offer, but asks for time to do the job.
In the morning, Jackson sends Hyatt to Fletcher's farm. Hyatt finds Kate alone, and she reveals that her impoverished parents had traded her to Fletcher. Fletcher returns and threatens Hyatt with a knife, but Jackson arrives in time to defuse the situation. Hyatt says he wants to use nitroglycerin for his part of the heist, so he, Jackson, and Lomax sneak onto Jackson's old ranch to steal some from Pierce. Jackson keeps Pierce distracted by pretending to collect some of his old things, while Lomax and Hyatt crack a safe and take the explosives.
The next day, Hyatt rigs a bridge with bottles of nitro, Levi blocks the war wagon's route with a felled tree, Lomax and Jackson set up a booby trap in a narrow gorge, and Pierce and his guards set out with the gold in the war wagon. Kiowa warriors create a distraction that briefly draws off the wagon's guards, causing them to be stranded on the other side of a canyon when the bridge explodes behind the wagon. Some more Kiowa warriors attack the wagon to get the gold for themselves, but a newly installed Gatling gun forces them to retreat.
The fallen tree diverts the wagon into the gorge, and Jackson and Lomax spring their trap, killing the drivers. Pierce shoots the last two of his men when they try to desert him, but the second shoots back as he dies, killing Pierce. The wagon crashes into a gulch, and Jackson's team hides the gold dust in some barrels of flour on Fletcher's cart. The Kiowa warriors arrive to take the gold, and Fletcher is killed when he attempts to stop them. Hyatt manages to use the last bottle of nitro to kill the leader Chief Wild Horse and scare the remaining warriors away. The explosion spooks the cart horses; as they flee, the flour barrels fall off the cart and break open next to a group of evacuating Kiowa women and children. Unaware that there is gold mixed in, they gather up the flour to feed themselves.
Jackson reaches the cart first. In a hidden compartment, he finds $100,000 worth of gold that Fletcher intended to steal from his partners. Thinking they have lost everything, Levi returns to the Kiowas, and Lomax angrily takes Jackson's horse as payment. When Hyatt arrives with Kate, Jackson gives them a small amount of the dust, hiding the rest. When a furious Lomax confronts him, Jackson smugly tells Lomax that he has to be kept alive until the group meets in six months, as planned, to divide up the loot.
