Edward Beale is in charge of finding a shorter trail across the American desert and to also test the practicality of using camels in the west in this 3-D western. (An actual test once conducted in the Big Bend area of Texas.) Clint MacDoanld, a bank robber one jump ahead of a posse, joins the caravan by posing as a doctor. His sweetheart, Lilly, also comes along and signs on. There is a whole lot of footage of the grueling trek across the desert, but it begins to move when mule-skinner Matt Carroll becomes aware of MacDonald's true profession and he wants the gold from the bank robbery. The Apaches have shied away from attacking the train, because of their fear of the camels, but a camel dies and the jig is up as they lose their fear and here they come.
