While trading at Fort Laramie Barnaby and Charlie meet old mountain man and legendary trailblazer Zebedee Titus who has come to trade his season's catch which is minuscule due to the few remaining beaver. After listening to his stories, they overhear him asking the trader and an Army Major for a job but be turned down due to his age which is near 80 years. Barnaby with support from Charlie persuades Chris Hale to hire Zeb as a scout for the wagon train. Coop and Duke are not happy with the idea especially when Zeb implies they will work for him. It becomes obvious that Zeb's eyesight is not what it used to be while out scouting with Duke. He can't see Comanche smoke signals nor hit a bear in a nearby tree, but Hale does not want to wound the old man's pride. Trouble starts when Zeb's mistakes lead to Coop's capture by Comanches.
