Davy Crockett, the nephew of his more famous namesake, is the scout of a wagon train travelling west across Indian territory in1848, accompanied by an Army escort. There is a spy among them who is telling the Indians of their whereabouts and activities. They manage to hold off the first Indian attack and then continue on. They have an option of two mountain passes through which to travel. It is clear that the Indians will be protecting one of the two passes. The Indians, on the other hand, attack as soon as they arrive. Someone has gotten wind of this.
