The girls must rock their way to the top, and outshine rival Adagio Dazzle and her band The Dazzlings, to restore harmony back to Canterlot High.

The mirror is a portal to a magical land with high schools instead of castles, and six pony friends become real girls full of fun and fashion.

Thiessen and co-director Ishi Rudell keep the action brisk and light, and cap the story with a glimpse of — what else? — the next Equestria Girls movie.
