Fran and Val go to The Rosie O'Donnell Show and Fran is picked out of the audience to talk to Rosie. She's so natural and funny that Rosie asks her to come on the show as a regular guest to give parenting advises. C.C. jumps in as her agent, and Fran starts to have a taste of life as a celebrity. Maxwell gets scared of losing her and makes up a story about a dream he had where a ghost told him something horrible would happen to Fran if she didn't quit the Rosie Show. Fran gets fired and is replaced by a retired couple from Florida.

Fran moves to her mom's because she doesn't want Maxwell to see her 24 hours before the wedding. Maxwell's sister arrives for the wedding and says their mother is not coming because she doesn't like Fran, which concerns Maxwell, but after awhile he gets over it, after realizing that it's not important. Fran goes to Jersey to pick up her sexy white negligee that she had ordered specially for their wedding night. On their way back, Val's car breaks down in the middle of nowhere, and Sylvia, Val and Fran have to spend the whole day waiting for someone to rescue them. Maxwell is visited by a very special someone: Sara, his late wife, who comes to wish him a happy marriage and confess that she sent Fran into their lives. Val's mother call Maxwell and goes to rescue them.

Aunt Freida decides to get back at Sylvia for not letting her sing at the wedding and buys her condo, leaving her with no place to go. Sylvia and Morty move in to the Sheffield mansion. At first, Fran is worried about how Maxwell is going to take it, and happy about having her mom around like old times. But Maxwell surprisingly takes it well as Sylvia spoils him like the mother he never had. Fran, on the other hand, starts remembering all the annoying things about living with her mom, and decides she must convince Freida to give her mother's condo back. They make some alterations on the wedding video to make it look like Freida sang on it, and the two sisters-in-law make up. Meanwhile, Niles experiments being a model for a day.

When Libby, the Chatterbox hairdresser/fortune teller, predicts Val will hook up with Fred the pharmacist and it happens, Fran worries her prediction might come true too. Libby said she saw Maxwell in bed with a leggy blonde in Beverly Hills. Coincidentally, Max has to fly to L.A. because his pilot was picked up. Fran and Niles assume the leggy blonde is Ms. Babcock and fly after them. After meeting Fran Drescher at the hotel lobby, they discover C.C. and Max changed rooms after Niles crawls up Max's bed! Turns out he's the leggy blonde! Meanwhile, Brighton has problems telling his father he doesn't want to go to Harvard and wants to take a year off instead.
