Mentor is hit over the head and robbed. Young Larry Burns knows that it was Ron Craig who robbed Mentor, but is threatened that he'd better keep quiet, or else... Billy and Mentor know that Larry knows who the robber was, and when Ron is seen looking for Larry, it becomes obvious that Ron is the guilty person. Knowing he's been found out, Ron forces Larry's father to take him out of town on his helicopter. Moral: Some day you may see somebody do something wrong. If you don't know what to do about it, just remember that when a problem has you stumped, it's a good idea to talk with a grown-up you can trust. It could save you a lot of trouble in the long run!
