A story about a boy and his grandfather and a German Shepherd named Blaze. The boy is an orphan, living with his fussy aunt and uncle. The grandfather lives far away and raises German Shepherds. The grandfather sends the boy a puppy, but the aunt and uncle immediately get rid of it, giving it away to the uncle's co-worker.

A year later, tragedy has struck. The kennel has burned down, killing all the grandfather's dogs. He comes to fetch Blaze, hoping to start the bloodline over again, but finds that the dog has turned savage from abuse and neglect. He takes the dog and goes home, not realizing that the boy has stowed away in the back of his truck.

Together the boy and his grandfather get to know each other and retrain Blaze.
