Michael Kelso was looking forward to the new, luxurious police academy, but doesn't want to go at all now because he believes he'll lose his friends and fears he may not make new friends. When Jackie's mother and gold-digging role model Pamela 'Pam' Burkhart arrives, Donna says she should welcome her - until Pam digs into her own dad, Bob.

When Kitty gives a cocktail-party, the men all dress up because of Jackie's sexy ma Pamela 'Pam' Burkhart, envy Bob who got another good looker after Midge and agree it must be a matter of money more then charm, while their daughters agree that mismatch may not go trough but are ignored. The doctor gives Red a heart monitor, but Kitty uses it as a lie-detector to trap him till it is proven to react to... Simple hedonist Kelso is the only one who uses Bob's hot-tub after the odd couple, au naturel, so his scumbag 'mates'...

After accidentally hitting him in the hospital, Eric tells Mitch he's welcome to hang out in the basement, even though nobody likes him.

Pam Burkhart moves back in with Bob Pinciotti, eagerly helped by the boys, especially horny admirers Kelso and Fez, but it's Red and Hyde who see her accidentally (but also on her part?) bare-breasted. A visit to the movie theater makes Donna admit to herself she's as horny for him as the other way around, forget pre-marital abstinence, but then he gets suspiciously greeted by a vending girl, and Mitch, who is back in the basement, hotly hoping to get Donna for himself against everyone's warnings he stands no chance ever, eagerly stirs...

Michael meets Brooke's mother Carolyn, instant antagonism, and she intends to take her home to Chicago while he's in police academy, he agrees for six months. Eric wakes up, Donna leaving him was just a nightmare, but Red warns him a trailer has no place no hide. Fez and Hyde are allowed to decide who may be best man: scissors, rock, paper, or ... Thinking about 'just wedding jibes' must be right for all future divorcés really spooks Donna, yet it's Eric who doesn't show up for their wedding rehearsal, just phoning...

Now Eric has left Donna practically at the altar, her mother Midge makes a surprise appearance to console her, to the ever-horny boys' delight as always. Midge finds Bob hooked up with Pam and acts jealous, so he takes Kelso's advice to plow both fields... When Hyde is shortly in hospital after a fall from the water-tower, accidentally pushed down by Donna, Kitty reads in his medical file he actually has another biological father, which he ignored, besides the dead-beat who completely abandoned him. He pretends not to care but eagerly accepts a 'coincidental' ride with the Formans and Jackie to his dad's fancy office in Milwaukee, but chickens out at the last moment. At night, Donna gets a surprise visitor trough the window, to closet-witness Fez's delight...

Red refuses to feed Eric until he gets a plan for his life. Jackie feels that Donna's new blond look will re-energize her spiritually and Donna vows to re-dedicate herself to feminism. Meanwhile Fez takes the first tentative steps towards establishing contact with a potential girlfriend and Kitty is scandalized that Bob is dating Pam and Midge simultaneously, forcing the anti-social Red to talk with him about it. Determined to have eat his mother's fried chicken for dinner Eric comes up with the plan: to do nothing and go nowhere for a year, deciding to hock Donna's engagement ring in order to finance his intentions.
