Taking a vacation in a nice relaxing and peaceful country? That's good.
Taking a vacation and being blamed for the the theft of some very important jewelry? That's bad.
Taking a vacation and becoming public enemy number one? That's really bad.
Taking a vacation and being hunted by adorable pegasi, unicorns, and ponies? That's... different.

A mage decides to take a respite in what he assumes to be the peaceful and safe land of Equestria. Unfortunately he's accused of stealing the "Elements of Harmony", a powerful set of magical regalia, and goes on the run from the law. Now stuck in a land of magical ponies, cut off from his only way home, and now the most wanted creature in Equestria, does he have any hope of proving his innocence and going home?

Maybe, but let's laugh at him as he gets beat up by cute equines!
