Wanda Snow has several times seen events before they have happened, causing several people on the wagon train to accuse her of being a witch. A medicine show peddler/magician gets the idea to use her in his act, but this creates friction between him and his devious partner.

The wagon train comes across old Jamison Hershey and Herman, his 3000 pound Belgian horse. The old man has made it safely through hostile Indian territory because the tribes are so in awe of his horse. Hershey and Herman are invited to ride with the train, though it becomes apparent that Herman is not able to travel very fast and may hold back the entire group.
