Comedy based on the animated series about the fictional antihero. When a group of corrupt school inspectors plan to close Henry's school, Ashton Primary, the headmaster of the neighbouring school sees his opportunity to make a fortune from the influx of new pupils. Henry puts together a talent contest, hoping that the success of his Zero Zombies Band will mean that no-one will dare close Ashton Primary. Miss Oddbot is not impressed and tells Henry that he should have thought about the future of the school before he started being horrid. Meanwhile, evil headmaster Van Winkle holds Miss Lovely, Perfect Peter and their friends hostage in his office.
