Twilight Sparkle is fascinated by the future and studies time travel spells with great diligence. While studying, she accidentally opens a portal into a strange world that seems vaguely familiar. Thrilled with the prospect of travelling through time, she and her friends step through the portal with Elements equipped, just to be safe.

As the last of them clears the portal it suddenly closes, trapping them in a world they have little understanding of. They must fight for their lives in order to return to the past. Their experience there may just end up changing their lives for good.
