Life in Ponyville, outside of the usual events like a parasprite invasion or a revenge-seeking, all powerful megalomaniac kicking out the town librarian, tends to be laid back and typical. Which Applejack doesn't mind. However, after the CMC cause more problems due to influence from a newcomer in town, Applejack gathers the girls to go fix what the CMC did.
But then a mysterious creature ends up attacking Applejack, and while she survives and seems fine, it isn't long before she starts acting strangely. It's up to the usual group of ponies to figure out what's going on before it's too late.
Strange things are happening with Applejack after a mysterious wolf-like creature attacks her when she looks into the aftermath of another CMC incident.
Applejack is back to normal and one of the greatest threats in Equestria's history has finally been laid to rest. But if that's the case, then what's going on with Apple Bloom?
