Everybody in town wears their pants at a different height: Mum is on the high side and the builders down the road are definitely on the low side. Harry Highpants wears his pants very, very high. Then Roy Bland, running for Mayor, decides to make a law saying that all pants must be worn at 'normal height'. As a result the kids organise a Free Pants Convention, a festival of pants. And Harry Highpants shows himself to be a pants champion, and strikes a blow for pants freedom!
