Strange things are happening around Canterlot High. So what else is new? A mysterious armor-clad figure protecting citizens from invisible monsters, that's what's new.
When rumors begin spreading that this nighttime warrior may be nothing more than a hoax, the HuMane 5 and Sunset Shimmer begin an investigation into the vigilante, but quickly uncover something far bigger than they had expected. Monsters from another universe are invading, reaching out from behind the mirrors…but through the darkness shines a helpful light. Is there a part for these six friends to play in this struggle against an unknown enemy attempting to conquer multiple worlds?
When you look in the mirror, what other than your reflection might be looking back?
