The Toff (the 'Honourable Richard Rollison') is in disguise as a helper at a holiday camp. He has been hired to pose undercover in order to investigate the mysterious disappearance of three male entertainers, or 'Red Coats' as they are known within the camp. He is assisted by the beautiful Liz Cherrell, another employee, who also features on various advertising posters being used by the camp. The mystery deepens as hidden money is found and there is plenty of action as fights break out and then murder. The Toff finds himself embroiled in a much bigger plot than anyone imagined, leading to a fitting climax at an airfield away from the camp.
