In Equestria, the newly crowned Princess Twilight Sparkle visits the Crystal Empire with her Ponyville friends for a royal summit with princesses Celestia, Luna, and Cadance. That night, Twilights crown and Element of Magic is stolen by the unicorn Sunset Shimmer, a former student of Celestia. After a chase through the castle, Sunset drops the crown through a magic mirror and follows after it. The princesses inform the ponies that the mirror leads to a different world, and they task Twilight with retrieving her crown on the other side before the portal closes again for thirty moons, or else the Elements of Harmony borne by her friends will no longer protect Equestria. Despite Celestias insistence that Twilight must travel alone, Twilights dragon assistant Spike anxiously jumps in after her as she enters the mirror.In the other world, Twilight and Spike are transformed into a teenage human girl and dog, respectively. While struggling to adjust to her new body, Twilight investigates the nearby Canterlot High School where she encounters several human students and faculty members resembling ponies in Equestria, including her friends Applejack, Fluttershy, Pinkie Pie, Rainbow Dash, and Rarity. She befriends the five girls, helping to bridge the animosity that Sunset created between them during her tenure as Canterlot Highs school bully. Twilight discovers that the crown has been confiscated by Celestia, the school principal, who mistakes it for a prop meant for the elected Princess of the upcoming Fall Formal. Twilight decides to run for Fall Formal Princess against Sunset, the reigning formal princess, to retrieve the crown. Sunset tries sabotaging Twilights campaign first by uploading a humiliating online video of Twilight behaving like a pony, and later framing her for wrecking the formal decorations in the school gymnasium. Twilights new friends, including Sunsets exboyfriend Flash Sentry, help counter these ploys and improve Twilights popularity among the students.
