When nice-guy Jeremy Martin (Jace Norman) puts on mysterious virtual reality glasses at the mall, he suddenly loses his “inside voice” and starts spouting every thought he has out loud. Making matters worse, Jeremy is running for student council president against his classmate Milly (Daniella Perkins), who is full of great ideas to improve the school. Desperate to get back to normal, Jeremy and his sister Victoria (JoJo Siwa) must figure out how to convince his brain that he can speak up for himself.
