When the writer's apology fails to provide the closure he seeks, Frasier tracks down the woman concerned, his former piano teacher (Constance Towers).

After Frasier admires a woman, Madeline Marshall (JoBeth Williams), featured in a magazine article on eligible singles in Seattle, Roz brings them together.

After Martin bemoans his sons' rarefied tastes and avoidance of all that is ordinary, they try to prove him wrong by fixing the toilet; they make the problem worse, call in a plumber, and find that they have hired Danny Kriezel (John C. McGinley), a bully who tormented Niles long ago, and his brother Billy (Mike Starr), who bullied Frasier.

With the help of Niles and Daphne, Frasier uses his psychiatric expertise to help Martin solve an old murder case that has puzzled him for years.

Shortly thereafter, a woman calls KACL, claiming to have spent the previous night with Frasier and canceling their second date.

Frasier's show is nominated for a radio award, but his concerns about Kari (Renée Lippin), an over-enthusiastic admirer whose attentions verge on stalking, make it a less-than-pleasant evening.
