Maxwell's brother, Nigel, is back to throw him a bachelor party, and Fran is terrified because Maxwell doesn't know that she almost married Nigel a year and a half ago. She tries to keep it a secret, but after Nigel gets drunk at the party, he tells Maxwell, just as Fran comes out of the cake in a surprise for him (after Sylvia confessed that Morty cancelled his wedding and ran off with the cake girl - Sylvia!). Fran and Maxwell have a fight over it, and they end up calling the wedding off, until C.C. (under the influence of Prozac) tells Fran that Maxwell didn't spend 5 years "doing the one man show". So Fran gets Marla Maples, who had a quick fling with Maxwell a year and a half ago, and confronts Maxwell. They finally realize they love each other and call the wedding back on.

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.
