Chief Tohpay, whose land has been stolen by the white man, is on the warpath. With modern military training provided by former army specialist John Garth they have taken a fort and captured Winchester rifles and a Gattling gun. Garth has been promised the hand of Tohpay's beautiful daughter Lohray as a reward, although she is unwilling to marry Garth. Reese and Chad are sent to investigate a town controlled by a crooked sheriff and armed Indian guards while Joe and Erik search for Tohpay's camp. All four are captured but break loose. Erik discovers the secret of the stone fire-breathing idol Tohpay has been using to convince his people that the God's support him. Erik uses this to discredit Tohpay as the other rangers try to capture the Gattling gun.
