Things are not looking well for Appleloosa. Vicious bandits plague the town, stealing and killing whatever they please. The buffalo tribes are preparing for another assault, bent on flattening the town and every pony in it. And their only hope for rescue is a short-tempered thief, a baby dragon with sticky fingers, and a reliable cowgirl assigned to keep the two crooks honest.

Masky, Patsy, and Applejack are in a race against time to hunt down the bandits before Appleloosa is ripped apart. But everyone in the seemingly-cheery settlement has a few secrets of their own, and nothing is ever as straightforward as it seems in the wild west. The ex-convicts have their work cut out for them--that is, if they don't manage to sneak away first.
