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.

Maxwell is offered to turn one of his failed plays into a movie, and tells Fran they might be moving to California! The deal is quickly changed from a movie to a sitcom, and Fran's afraid the news is going to devastate her mother. Sylvia takes the news surprisingly good. In fact, too good, leaving Fran suspicious about her. She goes to the Chatterbox after Sylvia, but Libby, the local yenta, tells her Sylvia's been seeing a doctor three times a week. Fran confronts Sylvia about her health and discovers Sylvia's been having an affair with her doctor, and that's why she doesn't want to move to California with Fran!

Fran delivers her twins as C.C. gives Niles an answer to his marriage proposal.
