Manolo and Marisol are two cousins who are starting their first day of high school together. They both share the same birthday, they each have a single mother and an older sister, and they share the same passion for music. They become friends with six aspiring musicians named Sacha, Anton, Jenna, Alyssa, Monica, and Chuckie who are all in their history class. The 8 of them decides to form a band together called "HOTE". They've audition for a few record labels, but found no success. They found out that their history teacher Freddie Herrera used to be a musician in his youth, so they ask him if he could help them get a record deal by being their band manager. He said no, not because he doesn't want to get their hopes up, but he is trying to hide his secret from his students that he's actually a warlock from another dimension. They find out about his secret, and they promise to keep his secret, but they still want him to be their band manager. He agrees, however they must help him find 8 crystals that are hidden under the school, because every 50 years, a mysterious darkness comes to the human world, and they must find them before the darkness does. Freddie's evil twin sister Dominique became a member of the darkness, but her brother or her family doesn't know about it, and knowing that she'll do anything to stop her brother from saving the world from the darkness, she decides to get a job as a PE teacher at the school, to spy on Freddie and his students and stop them from ruining her evil plan.
