Jamie's a small, nondescript 11-year-old when he falls in love with an elderly white greyhound named Silver Streak. When he gets a chance to own Silver, he seizes it although it means borrowing an impossible sum from the class bad boy. His mother won't let him keep the dog, so a newly determined Jamie hides him in a nearby bomb ruin.
