Billy Bunter is expecting a postal order from his uncle. At last he receives a letter from his uncle which he assumes contains the long-awaited postal order. However, before he gets a chance to open the letter, it is confiscated by his form master, Quelch. This triggers a whole sequence of hilarious events which almost leads to Bunter's expulsion from Greyfriars School. Martin Jarvis is in his element not only as a rip-roaringly funny Bunter, but also portraying the many other characters involved in the shenanigans giving each one their own individual personality.
