Audrey and Addie are distributing flyers outside of Dogood Books, the only bookshop in town. Nina, who is sitting in the driver’s seat of Mum’s car, demands to know what they’re doing. She is concerned because Addie didn’t come home from school on time. Nina puts both girls in the car and drives them home.

Back home, Addie waits for Keedie and has dinner. When Keedie arrives, Addie tells her that Audrey is helping her and reveals that she told Audrey about Bonnie. Upset, Keedie leaves the room, and Addie follows her. Keedie says that Nina and Dad don’t understand what it’s like to have to hide every day. Addie says that she doesn’t always want to hide and that she is afraid of suffering the same injustices that Bonnie did. Keedie promises that she would never let that happen. Addie then tells Keedie that someone made a response to Nina’s video, accusing Addie of not having autism.

The school is closed for a teacher work day. Nina will take care of Addie while their parents are at work. Nina is filming in her room when Addie notices that Keedie forgot her student card. Addie panics and recalls a tour of the university campus that mentioned how important the student card is. She decides to bring the card to Keedie and leaves without telling Nina. She buys a round-trip ticket and boards the bus. Due to her autism, she has a detailed mental map and can easily find her way to the university.

She arrives and goes to the administrative office, where she asks for Keedie Darrow. The admin tells her where to find Keedie, and Addie goes to the lecture hall and opens the door. The lecture stops, and Addie spots Keedie. Addie is struck by how unpleasant the sensory experience is in the lecture hall. Keedie rushes up to her and leaves the lecture. Keedie is worried until Addie hands her the student ID card. Keedie scolds Addie for leaving home. Keedie then becomes upset and begins to show signs of overstimulation. She checks her phone and tells Mum where Addie is.

Later, in the car, Mum scolds Nina for failing to watch Addie and tells Addie that she shouldn’t have left the house. Addie gets defensive. Keedie isn’t looking at her, and Addie asks why she is acting differently. Addie says that Keedie was struggling to speak in the lecture hall. Nina cryptically asks Keedie if it is “happening again,” and Keedie lies to Addie, claiming that everything is fine.

Addie and Audrey are almost late to school because they stop to play with a Labrador. Addie is developing a strong friendship with Audrey as they spend more time together. In school, Jenna asks to speak with Addie privately. They go to the girls’ bathroom, where Emily is waiting for her. Emily accuses Addie and Audrey of laughing at her and Jenna and makes several ablest comments. Addie stands up for herself and then leaves the room.

In class, Ms. Murphy hands out math books. Addie struggles with math, so she works out the sums in her own way, even though her method diverges from the one she was shown. In the library, Audrey says that she hates math, too. They talk about sharks; Audrey says that she doesn’t like them and prefers dolphins. Because Addie identifies with sharks, she grows defensive over Audrey’s negative language about them.

In the library, Addie returns her book about sharks. She is upset and says that she wants a book about dolphins instead. 

Later, Keedie and Addie go the village meeting together. They wait patiently as a woman called Miriam Jensen complains about littering. When it is Addie’s turn to speak, Mr. Macintosh preemptively denies her request, but Addie goes on to give her proposal anyway.

Miriam listens and asks Mr. Macintosh what his issue is with the proposal. He claims that it would be too expensive and time-consuming to consider. Addie declares that she will raise the money herself, but the council still says that the memorial would be too expensive. Miriam supports the idea of the memorial, and Addie insists again that she will raise the money. Several other people support her.

Mr. Macintosh says that, due to her autism, it would be unfair to let Addie try; he doubts her ability to succeed at her goal. Addie delivers an impassioned speech that triggers a new discussion. During the discussion, Addie thanks Miram, who displays signs of neurodivergence in her reaction. Mr. Macintosh refuses Addie’s proposal yet again, but this time, Addie isn’t as discouraged.

Addie visits Audrey at her house, and Audrey’s mother greets her at the door. Audrey and Addie plan to spend the whole day together. Audrey leads Addie into the forest, and in order to spare Addie’s feelings, she makes a special effort to avoid the Old Witch Tree, which is associated with the witch trials. As they walk, Addie asks Audrey about herself. Audrey reveals that she is named after the plant from The Little Shop of Horrors, a film that she, her father, and her brother, Daniel, used to watch on movie nights before Daniel went to Oxford. Audrey talks about moving to New York, an idea that makes Addie sad. Audrey takes Addie’s hand, inadvertently making Addie flinch. Addie explains that she dislikes touch because of her sensory issues.

They continue through the woods until Addie realizes that they are going toward Miriam Jensen’s house. Addie tells Audrey who the house belongs to, and Audrey sneaks over to the window, making Addie uncomfortable. Miriam spots Audrey and comes out to talk to them. Miriam is carrying a tortoise named Ernest. Miriam recognizes Addie and says that even if the money is raised, the village will refuse to build the plaque because the council members do not like to be reminded of that part of their past. Addie is determined not to give up. Miriam leaves, and Addie suspects that Miriam also has autism.

Addie shows Audrey her thesaurus, and they look up funny words together until Audrey starts to get bored. Addie remarks that she is getting better at recognizing when people no longer want to do something or talk about a certain topic. As they leave the library, they meet Jenna. Addie asks Jenna why they aren’t friends anymore, and Jenna reveals Emily’s declaration that Jenna would have to choose between being friends with her or being friends with Addie.

In the classroom, Addie reads about dolphins before shifting her focus to witches. She imagines how the condemned women must have felt when they were being tried as witches. Keedie meets her at the gates after school, and Addie introduces her to Audrey, who is surprised by Keedie’s appearance. A woman recognizes Keedie and comes over to see her, saying that she looks better these days. She says that Keedie seems “cured,” to which Addie archly replies that there is no cure for autism and that they don’t want one.

Later, Audrey and Addie try to raise money for the memorial. They stand outside the bookshop with flyers and a bucket for collecting change, and they eventually collect around £14. When it starts raining, Addie waits in the bookshop while Keedie walks Audrey home. Suddenly, Emily enters the bookshop with her father, who orders a selection of books with titles that suggest that Emily has trouble reading. While ordering books through the system, Cleo, the woman behind the till, asks Addie to show Emily around the store. At this, Emily flees the shop. Cleo tells Addie that some people are responding positively to her campaign for the memorial.

Keedie returns to take Addie home and tells her that she was proud of her at the meeting. Addie laments that she still can’t figure out how to get the council members to change their minds. Keedie helps her analyze the situation. Addie says that that the memorial is important because the history of violent prejudice scares her. She knows that if people don’t acknowledge that a certain action is wrong, this action might be repeated in the future. Keedie urges Addie to tell the council a story that will inspire them to care about her cause. Addie then asks Keedie what has been going on with her, but Keedie refuses to answer.
