It's 14-year-old Adam's first day as a teacher. All is going well until the ape-like Slab steals Adam's master key and wreaks havoc throughout the school. Now Adam must outwit the big oaf, or his first day on the job could be his last.
Struggling to keep his class in line, Adam creates a robot to discipline students. Unfortunately, it malfunctions and threatens to terminate Principal Tater. Now Adam must stop his creation, or he himself could be "terminated."
Adam learns that Echo is taking the same route home from school and is excited to walk wit her. That is, until he learns he has detention duty and the only way to get out of it is to prevent anyone from getting in trouble...including Slab.
