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.

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.

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.

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.

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.

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.

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.

As punishment for being "dope-heads", Red gives Eric and Hyde a curfew. Laurie is all for it until she discovers that it applies to her too. Red booby-traps the house so that he'll know if there are any escape attempts, and keeps increasing the discipline, despite Kitty's pleas for leniency. Jackie is still trying to convince Hyde that she's the woman for him, but he's not buying it.

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

Midge kicks Bob out of the house; he stays with the Formans and Red has to act as a go-between to try to mend their marriage. Kelso gets a new leather jacket that he thinks makes him look like Marlon Brando, but the everyone else thinks he looks like the Fonz.

Donna moons in a yearbook picture; Jackie claims Hyde as her new best friend; Kitty "clears the air" about Eric and Donna having sex.

Kitty and Eric go to the Hub after a dentist appointment and catch Donna (who's drunk) skipping school with Casey. Neither Bob nor Joanne can exert any authority over Donna, so a frustrated Red intervenes while everyone watches. Meanwhile, Jackie suggests that Kelso kiss another girl so that they can reconcile. And Hyde and Fez try to decide what to do with some dead fish that they stole.

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.

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.

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.

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 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.

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.

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.

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.
