Piper is excited to move to a new state and catch up with old friends. But the move doesn't go as smoothly as she expected: Piper has trouble feeling accepted in her new surroundings. But then she meets Arizona Smiley. Arizona is an avid stamp collector and bowls in a league. Piper is intrigued by Arizona's originality and before long, she wins Arizona's affections, and the two become great friends. This move turns out to be the best one yet, and Piper is eager to spread her trademark "Get Off the Bus" catchphrase once again.
