It has been ten years since the Cutie Mark Crusaders died.

Or so the world thinks. Only few know that, faced with the blame for a terrible crime, the Crusaders went on the run, and have now built new lives for themselves as vigilantes fighting for the oppressed and the downtrodden. Overall, it is a happy existence full of excitement and adventure that keeps them from thinking too much about what they left behind.

But what happens when the Crusaders' newest job takes them back to the one place they had vowed never to return: Ponyville? Shall they finally be able to clear their names and bring justice back to the town? Or might facing the past have even more painful consequences than the Crusaders realize?

Either way, it may just be the most explosive homecoming ever.
