Litigation lawyer Liam Foxwell attends a
performance appraisal. Agonising over it, he repeatedly watches the "re-do" on his "grain", an implant which records footage from a person's eyes and ears. Arriving at a dinner party for his wife Ffion and her friends, he finds Ffion laughing with Jonas. Throughout dinner, Liam scrutinises Ffion's reactions to Jonas, whose engagement recently ended. Jonas jokes about a time when his fiancée was waiting for him in bed while he was downstairs masturbating to a re-do of him having sex with a different woman. The other guests react negatively at this joke. Another guest, Hallam (
Phoebe Fox), talks about how she lacks a grain after being "gouged"—an attacker cut into the skin behind her right ear to steal her memories. Improper removal of the grain can blind the victim. Liam invites Jonas to his and Ffion's house, but then exaggeratedly remembers how late it is and Jonas leaves. Ffion invites the babysitter Gina (Mona Goodwin), who was looking after their daughter Jody, to sleep upstairs. Liam asks Ffion about Jonas, and she identifies him as a brief paramour from
Marrakesh. She says they dated for a month, but Liam shows a memory of her saying that she dated "Mr. Marrakesh" for a week. The discussion becomes heated, Ffion referencing Liam's former obsession over another man Dan, and Liam calling Ffion a bitch. They reconcile and have sex while watching memories of their past sexual encounters. Afterwards, Liam goes downstairs and drinks copiously while watching re-dos of the dinner party. When Gina awakens, Liam asks for her opinion on the memories. Embarrassed, Ffion gets Gina to leave. Liam interrogates Ffion further. She now says that her relationship with Jonas lasted six months. Liam drives to Jonas's house—ignoring his car's warnings that drunkenness invalidates his insurance. Jonas is unhappy to see him. They both enter the living room along with Hallam, who apparently spent the night with him, which Liam scoffs about. Liam begins to drink more while asking Jonas passive aggressive questions like if the lamp in the room is from Marrakesh, if he had sex with Hallam to later watch as re-dos, and if he masturbates to pictures of Ffion in the room, all while playing it off as just a joke. Jonas continuously tells Liam to leave, which he ignores. This escalates into a fight between the two. Liam wakes in his car, which crashed into a tree, and replays his memories. Assaulting Jonas, he made him delete his recorded memories of Ffion. While this happened, Hallam called the police. Liam spots Ffion’s memory of Jonas in his bed. He asks Ffion about it. She lies at every step until Liam presses further: after Liam left home over an argument about Dan, Ffion had drunken sex with Jonas around the time Jody was conceived. Aggressively, Liam demands she play the memory, and she does. Later, in an empty house, Liam re-watches memories of Ffion and Jody. He uses a razor blade and tweezers to remove his grain, and the screen cuts to black as he pulls it out. ==Production==
