It's Daphne's birthday, and Niles' gift to her is a romantic Hawaiian vacation. That reminds both Daphne's mother and Roz of the men they've recently lost. After the party, Frasier comforts Roz as a friend, but they wind up in bed together, for the first time after numerous close calls. When Roz runs off the next morning to Wisconsin for a family reunion that she previously had been dreading to attend, Frasier fears their friendship might be permanently damaged. He goes to Wisconsin after her to make sure they're still friends. Meanwhile, Niles decides to give his half of the vacation to Mrs. Moon, so that he can secretly fly to England to try to convince her husband to come back to her.—Anonymous

It is Daphne's birthday which culminates in everyone giving Daphne her presents: Frasier and Martin buy her a journal, while Niles surprises her with a trip to Hawaii for just the two of them. Daphne's mother's constant moaning leads to Daphne wanting to change her birthday wish. After the party, Roz does not want to go home, as she would be alone; Alice is at her grandmother's. This leads to Frasier and Roz spending the evening in conversation. However, both of them get a shock the next morning when they realize they slept together. Frasier tries to get Roz to talk about what happened, but she wants to leave as quickly as possible. After listening to Daphne feeling sad about the fact that her father will not be able to give her away at her wedding, Niles has a brainstorm. He asks Daphne to take her mother to Hawaii to try to cheer her up. There is a method to his madness: he is planning to fly to England and try to convince Daphne's father to come to Seattle and reconcile with Daphne's mother. Frasier, meanwhile, is worried that Roz's refusal to discuss what happened between them will endanger their relationship, so on hearing that Roz has gone to visit her parents in Wisconsin, he decides to fly there and see her. So Martin drops Daphne and her mother off at the airport, followed by Niles, then Frasier. He stays at home with a new robot dog for company, although only Eddie seems to be able to make it respond to commands. Roz's family mistakes her for Roger and Roz is surprised by his sudden arrival. Finding a moment to themselves, the two talk things out about their relationship and how good friends would do anything to keep them in their lives. At the same time, Niles finds Daphne's father, Harry, drunk in a pub.
