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.
