Season five of Frasier opens as the titular radio psychologist (Kelsey Grammer) spontaneously bids a brief adios to Seattle and flies off to Acapulco. Here he is smitten by voluptuous supermodel Kelly (Sela Ward) -- but of course it isn't all about sex, or so Frasier tells himself, since Kelly is also extremely intelligent, a Ph.D candidate in zoology. Back home, Frasier's brother Niles (David Hyde Pierce), father Martin (John Mahoney), and Martin's live-in caregiver Daphne (Jane Leeves) become convinced that Kelly (whom they've never seen) is merely a product of Frasier's hyperactive imagination! ~ Hal Erickson, Rovi
