After cousin Allison leaves Sugarbakers, Julia needs cash but is refused a bank loan. To cheer themselves up, the women play poker with a wealthy client -- who wins the business from them. Sugarbaker's could use an infusion of cash, and at a rowdy party given by potential new client B.J., the gals kick up their heels in wild abandon.
In an attempt at spontaneity, a carefree Mary Jo takes off for Nashville on ""a hen party on wheels"" with Julia and Bernice, but become terrified when a trucker Bernice flirted with at a diner pursues them. Meanwhile, back at the office, Carlene and Anthony put their noses to the grindstone studying for midterms.
A steamy love letter from another woman found in James' safe-deposit box shatters B.J.'s image of her late husband as a faithful companion worthy of her trust. Meanwhile, reveling in the destruction of her old car, a symbol of her days as a suburban housewife, Mary Jo goes wild in a new red convertible.
After eye surgery, Bernice overhears the gals talk of putting Mary Jo's dog out of its misery and figures they're planning her own mercy killing, so she barricades herself inside the storeroom. Meanwhile, Julia gets caught listing to a London phone line which plays tapes of Princess Diana's private conversations with her boyfriend.
With Sugarbaker's in such bad financial shape, the ladies are grateful when B. J. gets them a job redecorating a house that resembles the great home from Gone With The Wind --- until they find out that the new lady of the house plans to rip out the grand staircase and replace it with an elevator. To make matters worse, B. J. finds out that their client is trying to take over Poteet Industries and plans to give Sugarbaker's to his young bride Kiki --- renaming it ""Kikibaker's"".
With Julia continuing to fight to save the antebellum Kearney mansion, B.J. struggles to save Sugarbaker's and Poteet Industries from a take over from the Kearneys. However, despite their efforts, Kiki Kearney announces her new plans for ""Kikibaker's,"" Lester Kearney announces that the purchase of Poteet Industries is complete, and the modernizing of the mansion gets under way. Though Anthony and the women are fired for insubordination, when Craig, a friend of Mary Jo's, stumbles on some embarrassing news about the Kearney's illegal financial activities, Poteet Industries and Sugarbaker's are saved from the take over.
