Kelso decides to help Jackie and Hyde get back together with hilarious results. And Eric realises that the sadder Donna becomes, the more she wants sex. Kitty decides to help Red with his new doctor-imposed diet.

It's Eric's 18th birthday and nothing is going the way he wants it. He expects a birthday breakfast and suprise party from his mom, but Kitty is too preoccupied with resuming her sex life with Red. Plus, it's Donna's last day before moving to Madison for college and Eric is struggling with letting her go. In the end, Donna manages to salvage the day with the gift she gives him at the bus station.

No one in the gang believes Kelso's claim that he hooked up with Brooke, a beautiful and conservative older girl, at a Molly Hatchet concert. Much to Kelso's shock, Brooke denies knowing him and rejects all of his advances. Brooke's presence also disrupts Jackie and Hyde's relationship when Jackie asks for his opinion about Brooke's looks. Also, Fez decides to pursue college-bound virgins while Eric learns of an interesting collection kept at the local library.

A representative from INS is coming to find out if Fez's marriage to Laurie is for real. To avoid deportation, Fez must stay with the Formans and get on Red's good side. Donna encourages Kelso to take responsibility for his actions by talking to Brooke about the baby. But for some reason Brooke decides to let him off the hook.

After Eric loses his job, he finds himself up for the same waiting job as Kelso at the Holiday Hotel; Donna and Jackie send newly single Bob a box of fudge to cheer him up; Red tries to help Fez and Laurie get divorced.

The cheerleaders kick Jackie off the squad, so she invites the gang to the dance to give her popularity a boost. Kelso visits Brooke at the library in an effort to start a friendship with her. Christmas Eve is going to be "Hot Donna's" first shot at being a DJ at the station she works at. And Kitty signs Red up to be the mall's Santa Claus, sparking a rivalry between him and Bob.

Eric sleeps in after a late night playing poker with the guys after work. However, he tells Donna and Kitty that he was working the entire time so that he can get their sympathy. Fez volunteers to drive Red to the doctor's office but receives no gratitude in return. Brooke and Kelso go on an awkward double date Hyde and Jackie. Later, Brooke is introduced to Roy, who's instantly smitten.

It's Kelso's first day as a police cadet and he gets to drive around in a police cruiser with a real cop. His first stop is the Forman house to break up a domestic disturbance (Fez and Laurie are fighting over her sex life). The encounter leaves Fez burning mad, but he gets a chance for revenge when Kelso leaves the cruiser unattended. Meanwhile, Eric attempts to fix the water pipes and lawn mower in order to prove to Red that he's not a failure. And Jackie joins a Big Sister program at school.

Kelso freaks out when Roy suggests that he may be this year's police academy stooge. The only way to know for sure is to check his file, so Kelso decides to break into the police academy with Hyde and Eric. Meanwhile, Fez is expecting to take a final exam at the INS before finally becoming a U.S. citizen. Donna, Kitty, Jackie, and Red all tutor Fez on their versions of American history.

Kelso is ecstatic when Brooke asks him to be involved in her doctor's meeting for their upcoming baby, but he runs into a problem when he can't find his van. Hyde is exactly the opposite of ecstatic when Jackie redecorates his room with bright colors and lights that looks like a girl's room. Eric and Donna also set out to discover (in Kelso's van) what Mount Hump is like. Red is also upset that Bob gave him shoes, until he reluctantly begins to like them.

Red goes to the heart doctor and finds out that they are going to send a psychiatrist to his house to find out what is causing his stress. Kitty, who believes they always blame the wife, isn't too happy about it, so she starts to act weird. Meanwhile, Kelso introduces his co-worker, Suzy (Alyson Hannigan) to the gang. He says that he likes finally having a girl as a friend, without liking her as a girlfriend. Fez tells Kelso that he likes her. As Kelso is about to tell Suzy about Fez, she tells Kelso that she likes him. So Kelso tricks both of them. He tells Suzy she'll be on a date with him, and tells Fez he'll be on a date with Suzy. They both find out and are upset with Kelso, especially Fez.

Before a romantic evening with Eric, Donna realizes that she's missed taking one of her birth control pills. Both of them completely freak out and seek out Kitty's advice. Fez is still extremely angry about losing Suzy to Kelso, so he "dumps" Kelso and returns everything his former friend ever gave him. Everyone in the gang tries to console the unhappy couple while Suzy plots to reunite them.

After the recent pregnancy scare, Bob and the Formans insist that Eric and Donna go for counseling at the church. During their first session, Eric and Donna lie to the minister about having pre-marital sex. Kelso has also been lying lately, telling Brooke that he's doing better at the Police Academy than he actually is. But lying becomes more difficult after there's a fire at the Academy.

Jackie's mother, Pam Burkhart (Brooke Shields) unexpectedly returns from Mexico. Everyone tries to convince Jackie to forgive her mother and welcome her back into her life. However, when Pam starts dating Bob, Donna and Jackie realize that Pam is still a gold-digger. Donna and Jackie agree to do whatever it takes to break their parents up. Kelso is scared to leave for police academy, but the guys force him to go.

When none of the guys will help Donna and Jackie in convincing their parents not to date, they come up with their own plan to try to lure Pam away and prove she doesn't really love Bob. Meanwhile Red's heart monitor keeps going off around Pam prompting Kitty to think Red is "extremely happy" around her.

Donna catches Eric 'taking care of business' in her bathroom and is completely horrified. Afterwards, Eric's friends and family tease him mercilessly and Donna can't even look him in the eye. Amazingly, Eric actually manages to make this embarrassing situation worse when Donna finds out what brought on his need. Meanwhile, Kelso, now calling himself "Mike" and sporting a moustache, goes on a major maturity kick, so Hyde and Fez decide to knock him down a peg or two.

Donna wants to take Eric to a department to register for wedding gifts but he doesn't want to go. Red tells him about the easiest way to get out of shopping: choose the ugliest thing so they think you are bad at shopping, and Eric tries it. Donna falls for it, but figures it out and sends him shopping with a wedding crazed Jackie, which he actually enjoys! Donna gets mad when she finds out and gets an enraged Hyde, who told Jackie not to do wedding stuff, to help her ruin their time. Red reads one of Kitty's "dirty girl" fantasy books, and learns a thing or two. Kelso tries to invent something, but all his thoughts have already been invented.

When the gang sees Mitch at a putt putt course, they laugh it up at his pathetic job until they accidentally hit him in the head with a golf ball. Feeling sorry for him, Eric invites him to join the gang in the basement. But it snowballs from there when Mitch obsesses over Donna. Meanwhile, Pam doesn't see what the big deal is about rejecting Bob's offer to move in together, since she is dating another man.

When Hyde and Red accidentally walk in on Pam and see her topless, they are shocked by her reaction. They try to keep it a secret, but Bob, of all people, spills the beans. Meanwhile, Donna finds out about a girl Eric dated while she was with Casey.

Much to Eric's chagrin, Donna agrees to be Mitch's date to his brother's wedding. While there, Fez meets a beautiful girl and pretends to be rich to impress her, but the big news is the shockwave Mitch makes at the wedding..... Meanwhile, Kelso takes Brooke to a baby class.

When Eric accidentally sees Donna's wedding dress, he unintentionally rips it. But he only makes things worse in an attempt to rectify the mistake. Kelso, Hyde and Fez get a canoe and Red is forced to find a sentimental wedding gift for Eric for his wedding.

When Donna gets a full time job as "Hot Donna" on the radio, she decides that staying in Point Place is the best thing to do. She also buys a very small trailer for her and Eric. While visiting the trailer, the gang is surprised to see Casey Kelso, who is now back in town. The guys continue their plans and have a bachelor party for Eric, who can think of nothing but why Donna wants to stay. The girls also have their own fun at a strip club where they are again surprised to see Casey Kelso as a non-stripping employee who drives a drunk Kitty crazy.

Everyone does their best to cheer Donna up after Eric disappeared before the wedding. Midge even shows up to console her daughter, but her arrival causes an awkward scene with Bob and Pam. Also, Hyde lands in the hospital after he takes Donna to the water tower for a talk. While Kitty looks after Hyde, she goes through his medical records and stumbles upon a life-altering piece of news.
