Gaspar, the lactose intolerant ghost, goes to school with his new friend, Hayden, and CJ, Hayden's big brother. When CJ is picked on by a bully, he doesn't tell for fear of being known as a "tattler." Hayden tells their mother that CJ is being bullied, and she reports it to the principal. But when the bullying still doesn't stop, Gaspar finds an imaginative way to help CJ.
