Luz, a self-assured teenage girl, accidentally stumbles upon a portal to a magical world where she befriends a rebellious witch, Eda, and an adorably tiny warrior, King. In order to get home, Luz must help them with a mission.

During Luz’s first day of Magic School, curiosity gets the best of her, and she finds herself thrown into the Delinquent Track, where she’s not allowed to learn magic.

Luz experiences Grom, Hexside’s version of Prom, and it’s not what she expects.

On a school field trip to the mysterious Emperor’s Castle, Luz strays from the group and into danger.
