Kelso returns on New Year's Eve 1979 to celebrate, while Red and Kitty rethink their plans to move to Florida.

The Foreman's have a garage sale and Hyde makes "special brownies" to help out. When Red, Kitty, Bob, and Midge accidentally eat a plate of the brownies, a stoned Red sells the Vista Cruiser.

Hyde returns from jail only to find Red beyond furious and ready to kick him out of the house. Afraid that he'll turn the other kids into dope fiends, Red asks Eric if Hyde has ever pressured him to do drugs in the past. Eric wonders if he should confess the truth to Red in order to keep him from forcing Hyde out. Elsewhere, Leo visits the Formans to speak on Steven's behalf while Donna uncovers the reason behind Jackie's new found obsession with Hyde.

The guys go see Star Wars and are all completely blown away by it. Red asks Eric to hang out with his boss's son now that he's started working at the plant full-time again. David was an awkward kid the last time Eric saw him, but now he's a hunk who likes reading Donna's short stories. Also, Laurie starts hitting on Kelso out of boredom.

Since no one else is around, Jackie confides in Eric that she thinks she might be pregnant. Eric passes the news on to Donna, who tries to get Jackie to tell Kelso. The incident inspires Donna to go on birth control pills. Her decision inadvertantly causes Eric a lot of grief when Bob and the Formans find out.

The guys paint a pot leaf on the water tower and Kelso falls off trying to fix it because everyone thinks it looks like the finger. Instead of going to the hospital they go to Eric's cause his mom's a nurse. When Eric goes to get her he walks in on his parents having sex. Having trouble sleeping and not being able to look his parents in the eyes leads his parents to believe he's on drugs.

Eric skips school with Donna, Hyde, and Kelso for the first time in his life. Unbelievably, the gang finds a keg in the middle of the road and sees it as a sign that they should throw a party. Problems arise, however, when they all realize that there's no beer tap after the party is in full swing. Meanwhile, Red and Bob have their suspicions about what the kids are up to and launch a full scale search of Point Place.

Eric has a new friend and Steven and Kelso can't stand it. Steven doesn't like him because he's rich and Eric doesn't give him a ride home anymore because Buddy has a Trans Am. Kelso, on the other hand, seems like a worried spouse. Eric starts to feel uncomfortable around him however when Buddy makes a move on him. Buddy apparently thought that Eric was also gay. And Red makes his first sale.

Red's mother Bernice has once again managed to make everyone miserable during one of her visits. While driving his grandmother home, Eric lashes out and tells her that it wouldn't kill her to be nice once in a while. Bernice promptly drops dead, leaving Eric to think he killed her. The entire Forman family (including Laurie and Red's brother Marty) comes together for her funeral while Eric gets drunk at a bar with the guys.

The gang goes skinny-dipping and Jackie gets sick. Hyde moves in with the Formans when his mom runs away with a trucker. Bob takes a liking to one of Midge's feminist friends.

The gang, looking for something fun to do on Halloween, revisits their old grammar school, where they find their permanent records. Looking through them, they find out some interesting things about each other. Fez discovers trick or treating.

Kitty is devastated after the police catch Donna and Eric having sex in the Vista Cruiser.

Hyde helps Jackie take a Zen approach to Kelso and Laurie, who introduce their relationship to Red at the Forman dinner table.

Donna finds a pair of panties in the Vista Cruiser and thinks that Eric is cheating on her with his lab partner. Everyone is in for a big shock when they find out who the panties really belong to. Red's doctor's appointment shows that he has high blood pressure, so Kitty puts him on a strict diet, which he finds inedible. Kelso gains a new nickname due to a mishap in the cafeteria.

Kelso invites the gang to an expensive dinner but skips on the bill, leaving Eric and Donna in the restaurant with no money. The two of them decide to shed their "square" personalities and get back at the gang. Bob is upset that Red didn't offer him a job at Price Mart.

Kelso drops Jackie off in Chicago, but she is immediately homesick and reaches out to the gang for companionship. Eric finds out at the last minute that Kitty deliberately hid a letter outlining the vaccination shots he’s required to have before going to Africa for the year. He has his final Circle with the guys only to finally be busted by Red! As Eric says his good-byes to everyone, Hyde talks to Leo about his true feelings for Jackie and decides to follow her to Chicago…with disastrous results.

Eric's 17th birthday is coming up and he really doesn't want a party. Unfortunately, it's extremely obvious that Kitty is planning a surprise party against his wishes – she's even invited his older sister Laurie home from college for the event. Eric enlists Laurie's help in calling off the party while Kelso naively tries to attract her interest. And Donna, who's unsure about the state of her relationship with Eric, gets advice from Jackie on what to get him for a gift.

The kids decide to go to a disco but Steven doesn't know how to dance so Mrs. Forman teaches him to dance. Mr. Pinciotti walks in on them in a compromising position and believes they're having an affair. Kelso gets jealous of Fez because he thinks he's putting the moves on Jackie.

Eric loves having Hyde as a "brother" because he does all of Eric's chores but when his parents start to prefer Hyde he starts to hate him. Hyde changes from the conspiracy minded trouble-making guy Eric loves to a total bore. Midge and Bob are having relationship problems. Red's old war buddy comes back and Red finds out that he's a swinger.

Donna finally sleeps with Eric, but when the guys find out that all they did was sleep, they tease him mercilessly. Hyde gets a job at the FotoHut, and finds out that compared to his boss, he's a workaholic. And Kitty has to work double shifts at the hospital, leaving Red to do the cooking.

Donna has had enough of the Golden State. She misses Eric, who, although she doesn't know it, is headed West - despite his parents' objections - to declare his love and bring her home. Kelso, however, has decided he has found the woman of his dreams in Annette, who is beautiful and believes in him. Back in Wisconsin, Jackie is a changed woman, thanks to a change in boyfriends.

While Eric Forman is swiping beer for his best friends Donna Pinciotti, Michael Kelso, and Steven Hyde, his parents Red and Kitty hint that he may be getting the old Vista Cruiser. Now Eric can drive all of his friends – including the new foreign exchange student, Fez – to a Todd Rundgren concert in Milwaukee. A minor snag occurs when Kelso's obnoxious girlfriend, Jackie Burkhart, finds out and invites herself along. An even bigger snag occurs when Red tells Eric that he can't drive the car out of Point Place.

Red gives Eric 40 bucks to buy a Christmas tree and says that he can keep the change for his party. So Eric, Hyde and Kelso cut down a tree off the interstate and keep the money. They spend the money on beer and Kelso buys Jackie a Christmas present. Laurie spikes the punch with rum and Jackie's friend's are all attracted to Fez all of the sudden. Red has to work on Christmas Eve and not long after he gets home cops show up at his door telling him that his Christmas tree was illegally obtained and that they have to confiscate it. Also Hyde has a thing for Donna.

Kitty thinks that it would be a good idea if Red and Eric become friends. She forces Eric to invite Red to go with the gang to a wrestling event in Kenosha. Bob tags along and seeks help from Fez and Hyde over Midge's decision to start therapy. And Jackie is super nice to Kelso now that they've done the deed.

It's career day and the gang must spend the day working with their parents. Eric goes to the hospital with Kitty and is amazed at all she has to deal with every day. Fez accompanies Hyde and interviews cafeteria lady "Gross Edna" while mother and son feud. Poor Michael spends the entire day trying to figure out what his dad does, while Donna is mortified by Bob's crazy promotional antics. And Red finally finds one of Eric's friends he likes: Jackie.
