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.

President Ford comes to Point Place; Red is chosen to ask him a question, but struggles as he tries to speak. Eric and the guys welcome the President by streaking. Donna has to wear an American flag jumpsuit Bob gave her.

Red's hours at the plant are cut, so he fills his free time fixing things around the house, much to Kitty's dismay. Donna beats Eric at basketball, which sets off series of contests between them. Midge and Kitty each give their kids some pointers on harmonious relationships. The guys tease Kelso for being "pig-whipped" by Jackie.

With her parents going to the Playboy Club over the weekend, Donna drops Eric some unsubtle hints that she wants to hang out alone with him. Unfortunately, Eric is so preoccupied with getting a job at the new Fatso Burger that he completely misses her signals. Kelso gets the idea to throw a toga party at the Pinciotti house, but Donna's less than enthused about the prospect. As for Eric, he quickly finds that work eats up a lot of his free time.

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.

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 and Donna go to the drive-in. Eric doesn't want Kelso and Jackie to go because they'd be competition but Donna invites them anyway. Fez's house parents think he's listening to the devil's music (a copy of Kiss' Destroyer album). Red and Kitty spend the evening out and almost get arrested.

Laurie comes home for Thanksgiving with her friend Kate. Eric is annoyed that he'll have to give up his room for their guest, until he sees how hot Kate is. Jackie alerts Donna to the trouble she could be facing now that a college girl is sleeping in Eric's bed. Kitty tries vainly to avoid her mother-in-law's phone calls as she prepares for Thanksgiving dinner.

Red's mother spends a Sunday with them and drives everyone crazy, except Fez. She seems to have a certain fondness for him.

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 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.

Jackie dumps Kelso after he makes out with Pam Macy and invites everyone but him to her parent's ski cabin for the weekend. Eric, excited about what this could mean for him and Donna, pays no attention to Kelso's whining about being left behind or Red's tips about driving in the snow. He doesn't realize that Hyde keeps hitting on Donna and Kelso plans on following them to the lodge. Also, Kitty gets mad at Red over a past indiscretion and Fez has his first experience with snow.

When Eric scratches the car, Red suspends his driving privileges, so the gang has to walk everywhere. That is, until Kelso's cousin lends him a car. They get arrested though because the car was reported stolen. With one phone call, Kelso calls Jackie and she tells him that she'll have sex with him once he gets out of prison. The whole incident was a mix-up and the gang is released.

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.

Valentine's Day is coming up, so Eric decides to ask Donna out on their official first date and give her his class ring. She breaks her study date with Hyde in order to go, leading Hyde to realize he only has one last chance with her. Red and Kitty discover they don't have that much in common with Bob and Midge anymore. And Jackie explains to Kelso how things are going to work now that they've "proven their love" to each other.

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.

Prom night is fast approaching and Eric gets a motel room as part of his "spontaneous" plan to "do it" with Donna on the big night. When Jackie finds out that Kelso asked slutty Pam Macy to prom, she gets Hyde to take her out of pity. Fez wants to take his pretty English teacher to the prom. As for the adults, they struggle with how to respond to Midge's idea for her future career.

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.

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.

Hyde meets a girl who's the female version of him. She tries to convince him to go to New York with her but he decides that it would be best if he stayed behind. Kelso and Red make smaller paddles for Pong. Fez feels left out of everything. Jackie tries to bake a pie for home economics project, but she ruins it every time.

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.

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.
