A transfer from a state school, John pushes open the door of Room 22 to find the most crucial part of his life he never knew existed; a teenage boy with the mind of a philosopher, who just so happens to be able to precisely analyse every detail of John's life, whilst being able to piss everyone else off at the exact same time.
