Sunset Shimmer runs out of pages in her magic journal to write to Princess Twilight Sparkle in Equestria, so she travels to Equestria to pick up another journal. There Sunset meets the unicorn Starlight Glimmer, Twilight's student, who is curious about the alternate world and receives Sunset's permission to visit with her. Meanwhile, Juniper Montage happens upon a hand mirror that is enchanted with magic from Equestria, showing her reflection as a famous and beloved movie star. Feeling resentful towards the seven girls for upstaging her, Juniper discovers the mirror can also trap objects and people inside it, which she uses on Sunset's friends in a fit of revenge. Sunset also becomes trapped in the mirror after returning; the combined magic of the seven girls' crystal pendants morphs Juniper into a giant diva. The mirror falls and cracks during Juniper's rampage, causing the world inside the mirror to collapse into a void. Understanding Juniper's desire for friendship, Starlight convinces her to release the girls before they fall into the void. Juniper returns to normal and receives the girls' forgiveness, while Princess Twilight gives Starlight permission to stay a while longer to experience the parallel world.
