This film has been hovering around in my bonce for years. Not much to go on I'm afraid.
Its set in a public school closed for the holidays. The headmaster is still there as are two boys who are the film's main characters. Can't remember much about plot except it is British, I think the school was near the sea, the headmaster was a Michael Redgrave type (can't find the film in his listings) and I'm positive it was black and white and from the sixties/late fifties.
Many thanks if you can help solve this.
