The time is 1877, the place the wild Wyoming-Montana territory. Will Anderson, a flinty old rancher, has a huge herd of cattle ripe for market when his regular hands, inflamed by gold fever, desert him. In desperation, he hires the only "men" available for the perilous 400 mile drive - a pack of scraggly schoolboys. Through skill and harsh discipline, Wil Anderson whips them from greenhorns into seasoned cowhands. But before the long drive is over, the boys discover that the price they must pay for manhood is a terrible one- murder and revenge!
