After some prodding from (and striking deals with) her Mom, Darlene agrees to go to the prom with David, where she has a surprise deal of her own for her boyfriend. Roger attempts to strike a deal with Dan, using the temptation of being able to make him a ton of money, but is met with a mixed reaction from the Conners. Roseanne attempts a surprise fix-up between Jackie and Roger for a couples' night out, but to Roseanne's surprise, Roger shows up with a date. His choice of date is a jaw-dropping, shock to everyone.

When it looks like the fixer-upper house Dan has invested in is going to pay off, the Conners are on top of the world. But when the buyer backs out, and one partner skips out, and the bills are due on the project-house, that world threatens to come crashing down. Pushed by Beverly's latest attempt at driving Jackie insane, Jackie finally blurts out to her Mom that she has been seeing a psychiatrist. Nancy decides she wants to have a baby, but her chosen sperm-donor turns out to be a real rotten egg. An unlikely source rides in who just may save the day for the Conners.

D.J. comes running in the house with a skinned knee. Dan and Roseanne take him to the kitchen to get fixed up, but when Dan slings open the freezer door to get ice, he accidentally hits Roseanne in the face, knocking out a tooth. After a few failed attempts earlier in their relationship, Darlene and David finally have sex for the first time. They also get the responses to their college applications. David doesn't get in, but Darlene does, prompting her to hide the truth... at first. Determined to be allowed to go to this art school in Chicago, Darlene enlists her Aunt Jackie's help to try and talk Roseanne into letting her go. Dan gets a job with the City.

Roseanne makes a deal with Jackie: if Jackie asks Fred out, Roseanne will ask their mother to become a silent partner in the restaurant and stay away; feelings hurt, Bev swears she won't have anything to do with either of them. Jackie and Fred go out; he wants them to keep going out, but she doesn't. Roseanne feels guilty about hurting Bev and wants her to do something hurtful back to lessen her guilt; Bev takes her up on that by selling her share of the diner to the very last person Roseanne expected...or wanted.

Trying to conceive another child, Roseanne puts Dan on a "lovemaking schedule", to no avail. Jackie discovers that she's pregnant from her one-night stand with Fred and hesitates about telling him. Roseanne has no problem spreading Jackie's good news to their mom and their friends, but is stopped before she can tell Fred. To relieve the pressure and disappointment, Dan and Roseanne decide to stop actually trying to get pregnant, and let nature take its course.

The Conners gear up for their favorite holiday, with their traditional flair for trying to out-prank one another. Roseanne, the queen of Halloween, falls for the various elaborate pranks pulled on her by her family, for a change. Nancy is upset because she is painfully aware that Dan doesn't like her, so Roseanne sets out to convince her she is wrong by insisting that Dan pull a prank on Nancy, before Nancy sells her share of the diner to Leon.

Leon manipulates Nancy and Jackie into voting to serve breakfast at the diner, among other changes, without consulting Roseanne. Starved for attention, D.J. steals and wrecks the family car while joyriding, and a stressed-out Roseanne lashes out violently, which she quickly regrets. The power play between Leon and Roseanne escalates, and Dan advises Leon to back off, but when he realizes that Roseanne is not just being paranoid about Leon, he steps aside and leaves Leon to Roseanne's mercy.

Roseanne decides to join the Lanford Women's Association to develop contacts for her restaurant, especially since Leon is opposed to her being the one to do it. In an effort to suck-up, Roseanne makes D.J. play with one member's weird son, Elijah. Dan discovers that Mark has dropped out of school and spending those evenings at the Lobo Lounge. In a special cameo skit at the end, the famous "Luke" and "Laura" from "General Hospital" compare hardships with Dan and Roseanne.

Roseanne and Becky try to convince Dan to hire Mark at the city garage. Riddled with guilt (and tired of Roseanne overworking him), David confesses to Dan that he was living with Darlene in Chicago instead of his mother's in Michigan. Furious, Dan throws him out of the house and tells Roseanne to take him to the bus station and send him to Michigan for real, but she takes him to Jackie's instead, then goes on a mission to guilt Dan into taking him back. Since Jackie wants nothing to do with Fred, she's upset that Roseanne has been helping him sneak financial support for the baby into her tip jar.

Nancy introduces her new girlfriend Sharon to Roseanne and Jackie. Sharon invites them to go dancing with her and Nancy at a gay bar and winds up giving Roseanne a romantic kiss. This freaks Roseanne out, but she has a hard time figuring out why. Jackie is openly uncomfortable about people assuming she might be gay, which prompts an amused Roseanne to behave like they are a couple.

Roseanne's attempts to prank everybody at Leon's Halloween party at the diner fall flat when it's revealed to her that Fred is gay.

D.J.'s old bedroom is being converted into a nursery for the new baby. After discovering that a new baby crib is out of her price range, Roseanne schemes up a baby shower in hopes of getting at least forty $10.00 gifts, that she can exchange for the $400.00 crib. This plan threatens to backfire when the gifts are mostly homemade, or are otherwise nonexchangeable. After being unable to work together to paint the nursery without squabbling, Roseanne reassigns Becky and Darlene to throw the baby shower instead, but the girls are still at each other's throats because Darlene refuses to pull her weight, sticking Becky with all the work. Roseanne gets David to throw a "guy" baby shower for Dan with the men at his shop, hoping for even more exchangeable gifts, but that backfires as well.

A new diner is opening up across the street from Roseanne and Jackie's diner, and they are worried that it will spell the end for "The Lunch Box". To promote the new restaurant's grand opening, the owners hire Pat Harrington Jr., who played Dwayne Schneider from the 70's sitcom One Day at a Time (1975). When Roseanne discovers that they have a salad bar, and are serving loose meat sandwiches, she declares war. When adding a waffle bar, staying open late, and dressing up the menu doesn't seem to work, Roseanne decides to sabotage the new diner with raw fish, only to wind up stuck in an exhaust vent over a stove. The cast of Stomp does a dance at the diner.

Roseanne finally gets to meet Leon's fiancé, Scott, and learns that they are planning a wedding. In order to free Leon up to travel to Minnesota to meet the minister, Roseanne volunteers to finish planning the wedding - which becomes "one gigantic, offensive, Roseanniacle ball of wrong". Leon develops a bad case of cold feet, and it is Roseanne to the rescue.

Darlene and David get married. Dan suffers a heart attack during the ceremony.

After a night of drinking with the New York socialites, Roseanne has a strange dream about the future of Darlene and her baby.

When Roseanne falls into a deep depression and locks herself in the bedroom, family and friends try their hardest to pick her spirits back up. When their efforts prove fruitless, they stage an intervention to rouse a lethargic Roseanne out of bed.

The Conners welcome baby Harris Conner-Healy home. Roseanne is delighted Darlene wants to live at home and work on her parenting skills. The family talks about their lives after winning the lottery and are glad they have all come out of it stronger people. Over a pizza dinner, Roseanne suggests they say grace to thank God that Harris survived and the family is together again.

Family and friends gather at the Conner house to celebrate baby Harris' Homecoming and everyone takes a turn chatting with the new addition to the family. Mark and Becky have some exciting news, as do Leon and his husband Scott. During dinner, Roseanne takes time to reflect on each member of her family and reveals she has been writing a book; everything we see is Roseanne's altered version of actual events. Roseanne reveals the true story and admits she changed whatever details she didn't like about her life and the people in it. In truth, the Conners never won the lottery; it was all a fantasy Roseanne created in order to cope with a devastating reality. In the final moments, Roseanne sits alone in her basement writing room. She goes upstairs, passing through the old kitchen and the old living room. Roseanne sits on the old couch with the classic afghan on the back and silently takes in the warmth and comfort of the family home as the lights slowly fade.

Roseanne and Jackie fight over who their mother will live with.
