It is 1847, and Christian Horn (Cliff Robertson) is the leader of a wagon train expedition from Ohio to seek a new life in California. The journey so far has been long, arduous, and perilous. Supplies are running low, morale is sagging, and to make matters worse, Christian's son has come down with a mysterious illness and has been battling a fever over the past week.
In search of water. Horn decides to explore a nearby hill a hundred yards away, but when he gets to the top of the rim, he spots a strange black road, traveled by giant wheeled monsters.
Where is Horn exactly, and how can he survive in this strange new world?
