An abused beagle runs away from his owner. On the road, he meets young Marty Preston and follows him home. The boy immediately forms a bond with the dog and names him Shiloh. His stern father won't let him keep the dog because it belongs to Judd Travers, a local hunter. After Shiloh is mistreated again, he runs away and returns to Marty. Knowing his father will once again make him bring Shiloh back to Judd, he makes a home for the dog in an old shed up the hill from the Prestons' house and hides him from his family. His secret is soon discovered when a stray attacks the dog one night and he must turn to his father for help.
