Muriel has gone to Australia on holiday to visit her mother, leaving Dudley in the care of their daughters. Jacqui has started a new job at Stanley Barlow's bookshop, leaving Susan at home to prepare meals for their father, although her cooking leaves much to be desired. Growing tired of the complaints, Susan suggests to her sister that they find their father a housekeeper. Duncan, meanwhile, is having problems with a jammed filing cabinet, and likewise hits on the idea of getting Dudley a housekeeper so that he can concentrate on drawing his cartoons; he finds one in Madge Carew, the bullying wife of handyman Arthur Carew. Susan engages a pleasant woman named Elsie Bates from an agency, whilst Dudley - not to be outdone - also engages a housekeeper; an attractive Swedish blonde named Ingrid. Chaos ensues when the three females meet and argue over the position.
