Reuben and Amy Corbin, brother and sister, are left destitute in 1886 when Quantrills Raiders burn their Missouri farm, kill their father, and ride off with all the livestock and supplies. Reuben swears that somehow, someday, he will find and kill the individual raider he saw gun-down his father. With no means of support, brother and sister decide to try for Oregon. They find work and earn enough money to join up with a wagon train. The wagon train becomes the platform for a continuous array of adventures, hardships and close, new-found relationships.
