Eric is torn apart because he desperately wants to leave home, but can't because he's needed at home after Red's mild heart attack.

Although everyone keeps meanly abusing Kelso, he proves himself a true friend by realizing Hyde and Jackie may play cool and aloof, they're obviously still in love, so Michael starts shuttle diplomacy, albeit without rendering any sentence correctly, and makes each believe the other apologized first... Eric's announcement he defers college at least till Red is recovered delights Kitty as much as it depresses Red his 18 years wait isn't about to end after all, and joining Red in the doctor's ruthless diet looked doable to Kitty only till she reads he list includes no booze. Meanwhile Eric discovers and enjoys that the one thing hotter then make up-sex is going away-sex, so anything with Donna anywhere is a '(maybe) our last time' excuse.

It's Donna's last night in Point Place, and it's also Eric's eighteenth birthday. He may not be getting the party he expected, and he has to tell Donna goodbye.

When the boys see foxy Brooke again, Kelso wants her to confirm they did it at a Molly Hatchett concert, but she doesn't even remember the Adonis, who just can't believe it: other girls pretend they did get him. Just admitting he finds Brooke hot too gets Hyde in Jackie's bad books, but he's not about to lie for her; Kitty assures her it just takes a few years of picking shrewd shrew-battles till a man just gives up 'disobeying'. Donna tells Kelso that Brooke is now a librarian, he keeps insisting -the other boys only now discover there is a library in town, and it has many Playboys! Later Brooke comes to the basement, but drops a bomb-shell...

Brooke announces the big news to everyone and Kelso comes to find himself increasingly excited about the prospects of having a child of his own; Laurie and Fez have their marriage closely investigated by members of the INS.

Eric is fired because Joanne broke up with Bob. Eric tries to get the job Kelso is also applying for.

Jackie invites the guys to her high school dance; Kelso ditches the dance to visit Brooke at the library; Kitty casts a reluctant Red as the local Santa.

Eric tells Donna and Kitty he worked late while he was actually playing poker with the guys.

Jackie joins a Big Sister program at school. Eric tries to become the new handy man around the house.

Kelso thinks he's the stooge of the police academy and, with Eric and Hyde, breaks into the police academy to check his file.

While Michael Kelso helps Brooke in the library, she invites him, impressed with his kind efforts, to take her to her next gynecologist's appointment. Alas his van is missing by then because Eric drove Donna in it to 'mount hump' by the lake, which she considers a romantic wedding site, even though Donna's dad Bob insists on a church wedding, but forgot the hand-break... Meanwhile Jackie, who considered the basement 'depressingly gray', turned Hyde's bedroom into a pink baby girl-room, yet he enjoys the fragrance and softness but won't admit so. Red even finds it 'un-manly' when Bob gives him a fine pair of shoes. Kelso tries to take Brooke to the doctor on his bike, but is again in disgrace, so he finds an alternative, which really impresses the boys...

Kelso introduces a fellow police cadet to the gang, a tomboy named Suzy Simpson. Comedy ensues when Kelso tries to set up a date between Suzy and Fez. Kitty becomes defensive when a stress management specialist visits Red.

Fez shooting a bunny turned police cadet Suzy off completely, she only wants to hurt people. Fez blames his poor mate and failing cupid Kelso, who tries to wait patiently and brings peace offerings, but gets them thrown back (in words, two are kept as Jackie advised as part of ruthless revenge) so now Michael gets mad at him too. Donna's late period makes her and Eric believe she's pregnant; he panics worst and blabs to Kitty, who first suggested they move, then promises not to tell but writes it down for Red and Bob, who only suggests to pass the baby for Donna's sister. After Donna gets worked up because Eric said she had to give up her career, it turns out to be a false alert. Suzy tricks Kelso and Fez to meet 'with her', then too much truth from each of them proves to be- good in an unexpected way...

Kelso burns down the Police Academy. Eric and Donna start marriage counseling.

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'...

When Eric is caught by Donna tending to his 'manly needs' in the Pinciotti bathroom, everyone acts as if it was an ax-murder: Jackie sees it as blackmail material to 'milk' for life, the others brand the boy as a weak pervert. Hyde and Fez regret having to miss how Eric will as always make this one 'even worse', but still go visit Kelso at the police academy, where the cadet has adopted the burly house style, grown the trade-mark mustache and adopted the cop name Mike. After he dutifully flushed weed criminal Hyde's contraband stash, the pair treacherously shaves him a Hitler-mustache...

Donna decides it's time for the next wedding preparations: choosing a wedding list, to the boys' anger only 'things at the table', nothing they like, and Eric is a wreck after a six hours shopping raid, so eager to take Red's advice: choose so badly she'll declare him shop-incompetent and do it all herself. Alas veteran Kelso gives the game away at first glance, so as punishment Eric must go shop wedding cloths with Jackie, who surprisingly knows how to handle a male shopping-stooge. Meanwhile Kitty and Fez catch Red enjoying reading one of her dirty girls books...

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...

Precisely because Eric 'forbids' Donna to be Mitch's date at his brother's wedding, she accepts; it's in the Holiday hotel where Eric takes that shift so he can watch and bug his rival; Jackie and Fez come as chaperons, she gives him 'tips' to court a country-club bitch just like her. Kitty convinces Kelso not to take pregnant Broke to a roller-coaster and horse-riding but to her baby-care-class in hospital; Brooke panics when her practical skills fall short of her book-knowledge, but Michael's babysitting experience compensates. Red has got cable TV to compensate for failing conversation with Kitty, but deliberately refused a connection for the basement; Hyde taps into it himself, but has no control over the (weather) channel choice. Mitch proclaims Donna his hot fiancé, leading to a public fight with Eric neither really wants.

Eric thinks he has cursed his upcoming marriage after catching sight of Donna in her wedding gown; Red looks for a very inexpensive wedding gift.

As their marriage looms, Donna stuns Eric by leasing a trailer and announcing she's ditching college in order to become a full-time DJ. Hyde drags Eric out to a strip joint, so Kitty decides to take the girls to a similar establishment with male strippers - which they discover is MC'd by Casey Kelso. As the evening drags on, Donna starts to worry whether she's made the right decision - just as Eric fears he's holding her back, and that it will end destroying their relationship.

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...
