Bright and cheery wartime comedy, in which the boisterous lads of St Michaels are evacuated to a remote castle on the Isle Of Skye. Of course the place is haunted (and being Scotland, it naturally has to be a phantom piper whose appearance foretells doom to any who hear him), but it also comes complete with a Nazi spying ring. Will Hay is on top bumbling form as science teacher Mr Lamb, who gets Isaac Newton confused with William Tell, and he gets able support from a young and exuberant Charles Hawtrey, and John Laurie doing his wild-eyed mad Scotsman routine. Fast-paced, and quite atmospheric in its gothic Scottish castle setting. Nothing creaky about this comedy.
