One Summer in Your Shoes begins with a clash between two rival groups of schoolboys in the local park. One group attends the town academy, the other the grammar school. It is the first day of summer break, and the boys gather on the field for what should have been a friendly football match—but tensions quickly rise.
Within this energetic and chaotic scene, two boys—Joe and Charles—have a magical encounter that changes their lives. A mischievous goblin named Minx uses her powers to swap their bodies, sending each boy into a world completely unlike their own.
