Mario Zampi directs this 1960s British feature spin-off of the television and radio sitcom 'Whack-O!' starring Jimmy Edwards. At the centre of events is Professor Jim Edwards (Edwards), the headmaster at Chiselbury School. Though the institution proudly belongs to the tradition of English public schools designed to breed gentlemen, the reality on the ground is somewhat different. Professor Edwards is only too aware of this and his cane is rarely far away as he attempts to impose order on the misbehaving hordes. The film also features Richard Briers in an early screen appearance.
