In 2032, the girl wants to go get her hair braided, but her dad locks himself away in his office. She looks forward to soon leaving for college. Recently, she has had strange dreams which she writes about in her diary but tries to tell her dad about, but he never responds, as he doesn’t ever want to talk about her mother again. In the garage, she finds a bunch of things, including her mother’s letter and diaries, as well as some storage drives. She decides to transcribe the audio recordings on them.

The first file is a report from 2023. There, two people interrogate a gardener. They charge him with the crime of desecration. The gardener talks about how he once stumbled upon a visitor at the cemetery. There, he watches the visitor write in a notebook, and in her bag, there was the insupa. The gardener stands beside the visitor, and they talk. Eventually, the visitor realizes that the gardener is deaf and gives him her notebook to write with. He says that he lives in a house in the cemetery.

The gardener takes the visitor on a tour through the cemetery. She asks for the British section, so he takes her there, where many soldiers from World War II are buried. She then asks for the Zambians, though the gardener only waves approximately at where they may be. She decides to sit under a big fig tree, after which the gardener asks if she wants to go to the chapel, but she shakes her head. The gardener suspects that she was listening to the mzimu.

Later, when the children come back from school and head inside for lunchtime, the visitor sits at a bench in the cemetery. During lunch, the gardener looks out from the window of his building to watch the girl. She looks at urns on the Wall of Peace, though he can’t make out what she’s doing. He doesn’t realize that she switched out one of the urns with her insupa. During the interrogation, he says he didn’t notice, to which his boss says that it’s against the rules to allow an urn in from the outside.

The gardener says that the visitor came every week for three months. He explains that, after moving into the cemetery, he has given a horn, as a necklace which points out when spirits are close, as well as an ubunga to sprinkle on his house. He says that the necklace glowed blue whenever the visitor visited.

In her garage, the girl continues to look through the things in her house. She finds an mpande, which her dad doesn’t tell her about, only that she should put it away. Online, in a book, she figures out that it’s a special shell worn by royalty and witches, though she doesn’t know what it’s for. She puts it under her bed and starts having strange dreams. She dreams of a tall tattooed man and her mother.

The girl also has the insupa, as well as a letter in which her mother asks the curator of a museum to return the insupa to her family in order to honorably restore their family heritage. In the letter, the mother says that the insupa was used by her grandfather to protect his people with the power of the wind, as he was chosen to do by his ancestors. In the museum in question, the insupa is still sealed and unable to be opened, indicating that the curators are not worthy of it. The girl wonders how the insupa and the audio recordings may be related. She wonders who the visitor of the cemetery was.

In an audio recording, the gardener talks about how, one night, he heard an enormous wind coursing through the cemetery. He wakes up, bringing his horn and rosary, and prays. Outside, he sees a blue disc in the air, by the big fig tree. He runs outside and sees that there’s a person, the visitor, beside the blue disc. The visitor picks up the insupa from the Wall of Peace and takes it to the British section. From the insupa, an enormous wind comes out and topples all of its headstones, as well as the grave of the governor. The morning after, it rains, everything is gone, and the visitor disappears.

After a few weeks, the girl researches the cemetery and finds out that it’s still around, having been restored since the incident in 2023. She asks her dad to drive her, and he obliges. There, she heads out and walks through the graves and flowers. She finds the chapel and the big fig free. Eventually, she stumbles upon the gardener, who welcomes her back and gives her the insupa. His horn glows blue, which she knows is wrong the busangu, the chosen magic.
