As Andi Mack celebrates her 13th birthday, she gets a surprise visit from her older sister, Bex, who announces she will be moving back in with their parents, Celia and Ham. Andi is thrilled about the news and wants to know what Bex has been up to. Bex shares a box of her memories with Andi, though before she does, Celia warns her about the secrets inside, which she wants to keep from Andi. When Bex later discovers Andi is smitten with a boy named Jonah Beck, she arranges to have Jonah give her a Frisbee lesson. Jonah realizes how skilled at Frisbee Andi becomes and asks her to join the Frisbee team at school, but as she decides whether to do so, she discovers he has a girlfriend named Amber. Feeling humiliated, Andi gets upset at Bex, who tells her it is okay not to be perfect. Andi feels better after Jonah texts her. Meanwhile, against Celia's warning, Bex shows Andi a picture hidden deep inside the box which shows Andi as a baby and Bex holding her. Andi finds out the truth: her sister is actually her mother. This infuriates Celia and Ham, but they know they must come to terms with this revelation. After taking time to process this huge change in her life, Andi eventually becomes curious about who her father is, but Bex is not ready to tell her yet. It prompts Andi to take the box to see whether her father's picture is inside it.

Andi tells her friends Cyrus and Buffy that she has joined the school frisbee team with Jonah, but has yet to tell them about the more important, life-changing discovery concerning her and Bex. While hanging with Andi in her shack, Cyrus and Buffy come across the picture of Bex with the newborn Andi, concluding Bex has a "secret baby" but not knowing that baby is Andi. Meanwhile, Bex tries to fit in at dinner when Andi, Celia and Ham play a memory game during the meal. Andi tries to impress Jonah by giving him a bracelet she made, a gesture which upsets Amber as she sees the two together. Later, when Cyrus and Buffy keep harping about the secret baby, Andi reveals to them that she is the secret baby while also telling them that Amber is wearing the bracelet she gave to Jonah. Both Andi and Amber stare at each other for several minutes, diverting the attention away from the secret baby talk. Cyrus and Buffy eventually get back to Andi's revelation and have some questions about it.

Since the revelation that Bex is Andi's mother, Celia still does not want Andi to call her by different grandmother names. After seeing Mrs. Devlin is the librarian at Andi's school, and recalling that has not changed since she went there, Bex encourages Andi into watching scary movies, which Celia has kept Andi from experiencing. That evening, Andi watches a movie called Shhh!, with Bex there in case she gets too scared, though Bex ends up falling asleep. The movie indeed scares Andi so much, that the next day, she falls asleep in class and receives detention, which prevents her from attending her first Space Otters frisbee match with Jonah. Andi finds out detention is held in the library with Mrs. Devlin, whose "shhh" to quiet her winds up re-triggering her frightened state from the movie. Meanwhile, Buffy joins the track and field relay team and her obsession with winning becomes costly. Later, as Bex goes through a box of things from her youth, and Andi learns more about her, Andi also stumbles across a picture of someone from Bex's past whom she believes to be her father.

After Andi questions Bex about the identify of the man in the photo she found, Bex is hesitant and continues avoiding discussion about Andi's father. Cyrus reveals the truth about Bex being Andi's mother to his mother, who later spreads the word across town. Andi receives supportive comments from Jonah and other students at her school, while Celia has an even harder time coping with the relationship change after her neighbor calls her "grandma", which leads her and Ham to take time away from home. In their absence, Bex persuades Andi to have her first party at the house. The party is attended by Andi's schoolmates, Jonah, and even Amber. It turns sour when Amber wants to know who Andi's real father is and asks Andi to reveal him to the guests, causing Andi to retreat to Andi Shack. As Bex starts talking to Andi, Cyrus warns them that Celia and Ham have returned, and the partygoers are told to leave.

After Ham sends Andi to bed, Bex tells him that Andi has been persistent with questions about her father. Ham tells Bex that the man who fathered Andi knows she exists, because he told him.

Bex is shocked that Ham informed Andi's father about Andi, but Ham made it clear that he needed to know and Andi needs to know about him. When Andi later questions Ham about her father, however, she gets no information. Although Ham has given Bex the email address of Andi's father, all that comes out of any communication is "hey".

Meanwhile, Jonah sets up Cyrus on a date with a girl named Iris, as part of a double date with Jonah and Amber. It goes sour when Cyrus gets sick on a carnival ride.

Buffy gets into trouble at school over her curly hair and is told by the vice principal to change it. This leads to her not hanging out with Andi, who starts asking questions after she sees Buffy and Bex talking at the Fringe. It boils over when Andi sees the two in the bathroom at home, but she finds out none of what is going on is about her. Buffy reveals to Andi that she messed up her hair while using a flatiron to straighten it and she went to Bex to have her hair fixed, since Buffy's mother is overseas.

Andi later gives Bex a lesson on how to properly throw a frisbee. After Bex lets one fly, Andi goes to retrieve it and then sees Amber with a guy, but it is not Jonah.

Guest stars: Stoney Westmoreland as Ham, Emily Skinner as Amber, Molly Jackson as Iris

After Andi tells Jonah about seeing Amber with another guy, Jonah tells her he will be okay. When she later receives texts to see him at his school locker, Andi rushes to meet him but also confronts Amber, who actually texted her from Jonah's phone and makes her out to be a liar. Hurt by Amber's actions, Andi questions whether she should be talking to Jonah, even though he feels bad about what happened. She contemplates staying home from school and gets help from Cyrus and Buffy to make her sick.

Meanwhile, Celia sees Bex is becoming more responsible around the house and later notices her working at the Fringe. Celia also notices Brittany, whom Bex babysat years ago, is Bex's boss.

While running track, Buffy meets a familiar face from Andi's party, Marty, who informs her that she is the fastest female runner at school. She finds herself in competition with Marty, who has the school's overall fastest time.

As Andi, Bex and Celia argue over Andi's going to school, they hear the doorbell. Bex answers to find a man at the door; it is Bowie, Andi's father. Bex introduces the two, informing them of their relationship, and they look at each other in surprise.

Bowie is excited to know his daughter Andi by spending the day with her, but Celia reminds them it is a school day. Bowie manages to get Andi excused from school, right after she learns from Cyrus and Buffy that Jonah and Amber have broken up, and Jonah approaches her with news she hopes is good. When Cyrus and Buffy later realize Andi is not around, they text her to ask where she is and what Jonah told her, but Andi is wondering as much about Jonah and asks her friends to find out. They end up meddling instead, with Cyrus convincing Jonah to follow his heart, despite his insecurities from the break-up, hoping it will lead him to Andi. Meanwhile, Bowie makes the most of his day with Andi, but when she worries about Jonah, Bowie drives her back to school. After she discovers Jonah and Amber have reconciled, she asks Cyrus and Buffy how this could happen, but the two keep silent about their involvement. Andi also tells them she spent the day with her father, while feeling guilty about cutting their day short, realizing he had only the one day, since he is a traveling musician. After Andi talks with Bex about Bowie and learns more about their relationship, the two discover Bowie in Andi's shack.

Bowie decides to delay joining his 40-city tour with The Renaissance Boys to be with Andi and Bex, but Celia allows him to stay at the Mack house for only two days. During his extended stay, Bowie meets Andi's friends at school and her teammates on the Space Otters. He records a video with them in it and asks Andi about the boy she keeps talking about, but she feels uncomfortable about her father being around her all the time. On the other hand, Celia is having a change of heart about Bowie after he cooks one of her mother's recipes. Bex and Bowie later have a serious talk at the place the two were last together before their split, with Bowie wanting to be in Andi and Bex's lives more; Bex assures him that he is already a part of their lives. Meanwhile, Cyrus gets offended over a text from Jonah which called him "girly". Buffy works on making Cyrus more like a man, but when Cyrus later asks Jonah about the text, Jonah tells him that autocorrect messed up the text and he really meant to send "gnarly".

Bowie starts to realize he has overstayed his welcome after Andi catches him in her bedroom on her computer and wants him not to invade her privacy. When Bex looks at Andi's computer, she sees the video that Bowie made and gets emotional. That prompts Andi to take a look as well and to talk with Bowie afterward, only to find him gone.

Andi misses Bowie, and Bex helps to cheer her up. The two buy a variety of vintage clothes, which Celia disapproves, causing her to start questioning Bex's being back home. After enjoying quality time with Bex, Andi begins to wonder why her mother left home at the time of her birth, and while Bex does not reveal any details to Andi, things come out at home when Celia suggests that Bex move out.

Meanwhile, Andi is concerned after Jonah passes her in the hallway at school without saying anything. She talks to him to find things are still okay between them. She also offers to help him come up with something for Amber's birthday, including how to express his emotions on her birthday card, but Andi is taken aback when Jonah thinks of her as a "pal" instead of something more.

Buffy's competitive nature hits a new low when she discovers one of her track shoes is missing and assumes Marty stole it. She retaliates by taking Marty's shoes and inflicting water damage on them. As for the missing shoe, Cyrus reveals it was in his mother's car, coming out of Buffy's bag during one of her rides home with him.

The episode concludes with Andi and Bex moving into a new apartment.

Andi and Bex struggle with adjusting to their new home, and problems with the electricity and appliances are making matters worse. Andi has been removed from the home she has known for 13 years, and it is taking a toll, from issues about her laundry and the warm meals to her ability to work on her art. With her crafting supplies in the Andi Shack, she and Bex head back to the Mack house to retrieve them. Celia and Ham notice the two and are willing to welcome them back into their home, but Bex stands by her decision to move out, though she does apologize to Celia for taking Andi without giving her any notice. Ultimately, as Andi's mother, Bex begins to realize what is best for Andi and allows her to go back to Celia and Ham. After Celia returns Andi to be in her new home with Bex, Andi starts to embrace Bex as her mother.

Meanwhile, Cyrus wonders where he stands with Iris, thinking their relationship is over. Intending to spend the day at a sporting event with her, Jonah and Amber, he winds up going with just Jonah after Buffy declines to be his date and the other girls think he has moved on.

A new principal, Dr. Metcalf, takes over at Andi's school. He meets Andi, Cyrus and Buffy, and tells Andi her leggings violate the school's dress code. Unaware at first about this dress code, the three eventually object to it when they see all the clothing prohibited. With Bex's help, they stage a protest at the school, with the participating students wearing prison outfits. As this is also happening on picture day, Cyrus gets concerned over how he will look, but Buffy convinces him to go with what they are wearing. Jonah reminds Andi about the team picture for the Space Otters, but when she shows up, he does not see her in the team's uniform and tells her to change into it. With Jonah so focused on the picture, Andi quickly realizes his indifference to her standing up to the dress code—a fight she wins after negotiating with Dr. Metcalf about making the policy more reasonable. Andi and her friends later find out the school will redo picture day in light of the protest.

Andi and Jonah have a more serious talk about what has happened, leading her to quit the Space Otters. She stands up to Jonah, wanting him to stop asking her to do things for him. When Jonah asks if they are still friends, Andi responds, "Were we ever?"

Guest star: Oliver Vaquer as Dr. Metcalf

Jonah is feeling down following Andi's quitting the Space Otters and all but ignoring him after their talk. Even Amber cannot cheer him up, with her friend Kip belittling the sport he loves. Cyrus encourages Jonah to talk to Andi, but when it appears Jonah will have a chance to do so in the school hallway, he notices Andi's excitement about Bowie's return instead. Jonah becomes so depressed that he cancels the Space Otters practice. This also leads to his unequivocal break-up with Amber.

Meanwhile, Buffy gives Marty a new pair of shoes, her way of apologizing for what she did to his old ones, though Marty has wanted her to actually say she is sorry. They set a time to race each other to resolve who is faster, but when they worry about how they will react to the result, they call the race off.

Andi discovers the reason Bowie came back is tied to Bex, whom he noticed in pictures across several stops on his tour with The Renaissance Boys. Andi arranges for her parents to have a romantic evening, and she also hears a song Bowie wrote for Bex. The next morning, Andi asks Bex how the evening went and hopes the two will get back together, but Bex tells Andi it is unlikely because Bowie's unpredictability makes him inclined not to stay in one place. When Andi talks to Bowie, she realizes his feelings for Bex have changed little over the years, but Bowie agrees with what Bex told Andi. Still, there is hope when Andi sees Bowie unexpectedly take a ring out of one of the blazers he is trying on at a vintage store.

After overhearing part of a phone conversation Amber is having with her father, Andi decides to spend time with her by inviting her to a sleepover. Having warned Andi before about Amber by comparing her to a snake in one story, Buffy relays another story to Andi about a frog and a scorpion, and compares Amber to the scorpion—leading to the term "snorpion".

Andi is nervous about holding hands with Jonah at school, but just as she is about to, the principal, Dr. Metcalf, splits the students into two separate groups, with Andi and Cyrus in group A, and Buffy and Jonah in group B. When Andi figures out that her group has luxuries while Jonah's group struggles over what they are dealt, she decides to switch groups and encourages the rest in her group to do the same, despite Dr. Metcalf's order for the two groups to stay separate. After chaos ensues in the cafeteria over cookies, Dr. Metcalf ends his exercise, getting across to the students that what group they belong in does not give them any advantage or disadvantage. He also asks them how he decided what group they went to, and while Andi contends it was random, she realizes his selections were alphabetically based.

On the last day before Buffy and her mother move to Phoenix, Andi and Cyrus are faced with saying goodbye. After Buffy makes a casual comment about bottling her memories with her friends in a time capsule, Andi and Cyrus decide they want to do that as a way to remember her. Despite her comment, Buffy is against the idea and feels disinclined to say goodbye to her friends. Andi and Cyrus work on building the capsule anyway, hoping Buffy will see it before she leaves the next morning. Jonah also contributes to it, adding a basketball signed by Buffy's teammates, as well as her team jersey. When Andi, Cyrus and Jonah go to Buffy's house that night to surprise her with the time capsule, they discover the Driscolls have already left, without a goodbye.

Buffy appreciates her time capsule and wants to peek inside, but the lid is on tight. Andi informs her about the contents, including her basketball jersey and a ball signed by her teammates, which Andi mentions was Jonah's idea. Jonah, meanwhile, tries out for the elite Ultimate team at school, with Cyrus there to support him, and to comfort him when he does not make the team.

After they say goodbye, she resigns to Andi Shack and finds Celia in there, who is dealing with Ham being away, so the two console each other.
