The Chisholms learn that the Virginia land they have been working has been deeded away. They decide it is time to pull up stakes and take their wagon west to California. When they get to Louisville, they hire Lester Hackett as a guide.
As the Chisholms move west, they notice a man is following them. Soon Lester disappears with Will's horse. Will and Gideon set off after Lester and the horse while the family continues on their westward journey.
