Hobo comes across a summer camp where he reunites with two boys whose lives he'd saved in previous episodes. An antagonistic and divisive counsellor uses their jealousy over the dog to set them against each other.
The Hobo finds a recluse, old man who has become estranged from his granddaughter--his only family. The Hobo seeks to find her and lure her back to her grandfather.
Two brothers enter a bicycle race to win prize money to buy their mother a birthday present. One boy is willing to do anything to win and the Hobo moves to level the playing field.
A TV reporter and a cryptozoologist discover the hobo when researching archival footage of his many adventures and seek to trap him. But since the prevailing assumption is that there are many dogs of his kind, there is talk of dissecting him!
A seismologist takes his family along on a field assignment, where they are threatened by impending earthquakes of which only the Hobo appears to be fully aware.
