Follows a group of GCSE students, and the staff who teach them, as they face the most important year in their education. Passmores School in Harlow, Essex, is a successful school in a challenging area. Under headteacher Vic Goddard, it's just been awarded Academy status and is rated 'outstanding' by Ofsted. Now the school has been rigged with 65 fixed cameras - from the corridors to the canteen, and from the headteacher's office to the detention hall - to reveal every detail of daily life.
