Former Get Smart regular Barbara Feldon guest stars as Diana Caldwell, the Emma Peel-like leading lady of the classic 1960s TV espionage series "Spy Girl." When Jamie (Helen Hunt) lands Caldwell as a client, Paul (Paul Reiser) and Ira (John Pankow) -- who have idolized "Spy Girl" since they were kids -- are all agog. The two Buchman cousins vie for Diana's attention, with Ira emerging the winner -- until he discovers that the woman of his dreams is something of a nightmare. And in keeping with all things '60s, there's Jamie's sister Lisa (Anne Ramsay) in go-go boots. ~ Hal Erickson, Rovi
