Preparing for his next presentation on "Robots across the ages" for Ms. Rose's class, Eugene digs around the scrap metal depository and finds a rare object : Robor01, the school's first ever monitor robot. He fixes it and gets a good mark but the teacher asks him to deactivate the robot, known for its lack of trustworthiness and for imposing unrealistic punishments. Eugene accepts, but when he leaves the classroom, he breaks his promise. It all comes tumbling down when Robor01 sees Nikils. The headmaster, who was a student back in Robor01's days, is recognised by the robot who would often terrorise Nikils. The Robot remembers Nikils still owed him a detention.
