The fourth form monsters' latest trick is their best ever – they have burned down St Trinian’s school! As the girls stand trial, the police breathe a sigh of relief, but miraculously the judge's infatuation with a student means the school is freed. For the authorities, it means a new reign of terror as the girls of St Trinian’s regroup with gleeful anticipation.
