The kids in Class 507 were so poorly behaved that their frustrated teacher quit her job right in the middle of the school day. However, the office never received the message. Class 507 had no teacher! The students quickly formulated a plan to keep this fact a secret, strategizing their actions to give the illusion that everything was normal in their room, except everything was not! Students tended to do what ever they wanted, wrestling, throwing objects, drawing, until parents started wondering why their kids had no homework. Things really got complicated when they realized their field trip was coming, and Class 507 was responsible for writing a play production they had to perform for the whole school. Maggie, the smartest kid in the class, gets all the kids on track by assigning lessons in class and assigning double homework, as well as having students write and prepare for the play. The students soon realize that keeping a classroom running is way more work than they thought!
