Needing extra money for Yetta's bridal shower, Fran is hired by to be Chester's dog walker. As Fran and Gracie are strolling in Central Perk, a man distracts them and steals Chester. He asks for $20,000 for Chester to be returned safe, and for that much money Fran and Val decide to take over the investigation and rescue Chester themselves, but of course they also end up being kidnapped. Now the kidnapping couple is asking for $40,000 to return the ladies and the dog. Mr. Sheffield goes out for the rescue, but Fran gets rid of the kidnappers with some laxative chocolate Yetta gave her.

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.
