Laura's efforts to dig up new customers for Mike's gardening business are too successful. Instead of thanking her, Mike gets angry and insists she learn more about the business

To combat her terror of the dentist, Laura is given sedatives that leave her light-headed and flirtatious. Her behaviour towards Mike results in a comic misunderstanding that threatens to worsen an already awkward situation after Helen asks them to house-sit when she and Phil go to Dieppe

Both Helen and Laura announce good news prematurely. Mike thinks he and Laura should buy a larger flat so that they can live more comfortably.

Mike gets jealous when a business associate of Laura's appears to have more than business in mind. Helen takes over Mike's office work, but she proves too glamorous for the job.

One Sunday, Laura longs for an adventure, but one after another her schemes fall flat. Then Harry arrives and suggests they all go out to dinner - in France.

In the process of furnishing their new shared flat, Mike learns how little faith Laura has in their future together. As Mike and Laura reach a new low in their relationship, Phil and Helen arrive with good news.
