It seemed like the start to a typical Monday at J. Waldron Elementary school, or so Johnny "the Whiz" Whyzinski thought. Once he entered those doors, it would become obvious that this was no ordinary day. Ms. Rose would be out sick for the day and they would have a substitute. Buster, the class hamster, would be missing from his cage. Did Buster run away? Was Buster kidnapped? It would be up to the Whiz to figure out where Buster went and what happened.
