Princess Gryph is almost done with her tour of Equestria, collecting centennial census data from all its towns and cities. Her last stop is Ponyville, where she meets the eager young princess, Twilight Sparkle, who insists on tagging along while she fulfills her royal duties. The tired, homesick foreign princess dismisses Twilight's initial enthusiasm, but eventually the two begin to learn from each other.

When Princess Gryph can't manage to keep a low profile and encounters setbacks, tensions begin to rise. As Twilight and friends help her mediate her desire to be home with her family and her need to calm her overworked nerves, it creates a new opportunity to rediscover friendship.
