Lynette balks at the idea of seeing a couples' therapist. Meanwhile, Katherine is seeing her own psychiatrist, Gaby and Susan are determined to find out which of if their kids are in the smartest group at school, and Angie disapproves of Danny's new girlfriend.

While in the Big Apple, a chance encounter with supermodels Heidi Klum and Paulina Porizkova leads Gaby to an unexpected revelation about herself. Meanwhile, Lynette and Tom are in for a big surprise when Preston returns from Europe; Mike is determined to show Susan what a man he is after feeling emasculated; Bree discovers a shocking connection to her new employee, Sam; and Katherine is confused over her feelings for Robin.

Susan's days as a sexy internet sensation may be coming to an end after she angers an important client and incurs the wrath of her boss, Maxine; Renee and Gabrielle are headed for a smackdown after each of them reveals an intimate secret about the other to the wrong people; Bree finds herself exhausted by younger lover Keith's sexual stamina; Lynette is angry with Tom after he asks his mother to become the baby's nanny without talking it over with her first; and housewife Emma Graham puts on a cabaret show -- with the aid of saxophonist Dave Koz -- with surprising results.

Lynette feels her mother (guest star Polly Bergen as Stella) is marrying Frank (guest star Larry Hagman), an abrasive and obnoxious man, for all the wrong reasons, and thus tries to talk her out of it. Meanwhile, Carlos becomes concerned when he learns about Gabrielle's obsession with her doll, and Bob and Lee hire a non-maternal Renee to decorate their newly adopted girl's bedroom. Bree runs into Keith's ex-girlfriend (guest star Rochelle Aytes as Amber) and learns some shocking news about his past, and Susan tries to befriend a curmudgeonly man (guest star Gregory Itzin as Dick) who has given up on ever finding a kidney donor. In the meantime, Paul appears to have some plans for Beth (guest star Emily Bergl), as he books a trip for the two of them to a remote cabin in the woods.

Tom and Lynette visit a couples counselor about their separation; Bree tries to help a city council about the homeless; Carlos is in a guilty situation; Susan is embarrassed about Andre's students being naked in class.
