The whole family go on holiday to France, a holiday which gets off to a bad start. However, when the family car is seen to have a crest on it, it is assumed that they are titled nobility. Mademoiselle Dupont, the pension's owner, calls Pop 'Milord' and gives him and Ma her bedroom. Even the grumpy receptionist is respectful. Primrose, the second eldest daughter, falls for local boy Marc-Antoine but Charley is annoyed to see his wife cavorting with skimpily clad Frenh hunks on the beach.
