Liz, the Eye Catchers secretary, gets the chance to star in a commercial filming in the Canary Islands and so Nell suggests Simon replace her with her friend Winifred, who has split from her husband and has time on her hands. Though efficient Winifred is no ray of sunshine and then Liz returns - her acting career cut short when the director got fresh with her. Simon cannot fairly sack Winifred so he plots to get her back with her husband, a double glazing salesman, on the premise that he needs new windows. The plan works and Winifred returns to her spouse, who has hit Simon with a big double glazing bill.
