Mr. Campbell has announced he's returning to Edinburgh to run his father's former practice, and so Sally is once again on the hunt for a new job. She fancies growing and selling her own mushrooms, but Campbell has put a good word in with the man taking over the lease on the shop.

Sally starts work for her dishy new boss, David, but is unsure whether he is unattached. When he asks her out for dinner her hopes rise, but her sons intervene and spoil her plans.

After discovering a stash of adult magazines, Sally decides that the boys are sex mad. When David suggests they meet his daughter at the weekend, she decides to give them a talk on love and babies - but they draw the completely wrong conclusion!
