A quartet of hunters go looking for wild hogs near Lake Okeechobee, and find a bit more than they bargained for. When Owen Cassidy falls into the lake and vanishes, his brother Trevor unwittingly follows him into Equestria. Separated from his brother, Trevor is forced to trek across an unfamiliar world full of creatures straight out of fantasy and legend.

Meanwhile, the ponies in Appleloosa have been struggling ever since members of their town began to disappear. All contact with nearby Dodge Junction has been lost, and anypony who heads that way doesn't return. Numerous letters have been sent to Canterlot asking for help, but due to the capital city's own problems no aid has been provided. Big Macintosh finds himself visiting the frontier town at the request of his cousin, to lend a helping hand bucking apples. However, due to a chance encounter he finds himself pitted against the very villains behind the kidnappings in the first place.

With fantastic monsters and powerful criminal gangs seemingly around every corner, it seems as though Trevor is in over his head here in Equestria. Armed only with his shotgun and his wits, he has a lot of ground to cover if he wants to find his brother and make it back home.

(Minor Gore Warning. Things get shot and bludgeoned and otherwise violently harmed, but it's not really excessive or anything. You'll probably be okay.)
