In September 2024, at the tail end of the
Brat Summer phenomenon and the apex of her fame, British pop artist Charli XCX prepares to begin rehearsals for her
arena tour debut while still regularly promoting the
Brat album. Despite the fact that she and her team find it "cringe", she is forced to continue the album cycle by her label,
Atlantic Records, who have a vested interest in maintaining
Brats cultural relevance by forging several brand deals. One of these is a
Brat credit card under Howard Stirling, a failing bank company, which grants fans a free ticket to the tour upon signup. Before a launch event for the credit card, Charli expresses her disdain for the deal and refuses to promote it on social media. Tammy Pitman, an Atlantic executive, is convinced to license the production of an
Amazon Music concert film documenting the Brat Tour, directed by Johannes Godwin, a pretentious filmmaker whose work Charli finds objectifying of women. He insists upon watching rehearsals, much to the dismay of Charli and her close friend and creative director, Celeste. Johannes takes over creative control, aiming to sanitize the original concept of the tour into something more family-oriented, butting heads with Celeste who tries to keep intact the original vision she and Charli had worked on. Spread thin by the continued promotion of
Brat, rehearsals for the tour, and Johannes's disrespect, Charli takes a sudden vacation to Ibiza which her assistant previously booked without her permission. Tensions between Celeste and Johannes continue to rise, the latter convincing Tammy to give him further creative control under the guise of Celeste being difficult to work with. In Ibiza, Charli attends an appointment for a holistic facial from Maria, a cold woman who insults her and says she should stop everything to have a child, before arbitrarily deciding Charli is too combative to continue. Later, Charli happens upon media personality
Kylie Jenner and confesses that many have been telling her to "slow down". Kylie gravely advises her that when people are growing sick of her, she should "go even harder". With two weeks left until the first tour date, an emboldened Charli argues with her managers over the phone, rashly deciding to post about the Howard Stirling deal as to quickly fund Johannes's expensive vision and smooth out the production. The next day, an exhausted Celeste watches as Johannes completely revamps the entire visual presentation of the tour. Charli returns from vacation and is displeased with Johannes's direction, but forced to continue as her own money is being used for it. His vision features several spectacular set pieces, including a giant lighter and cigarette, trite monologues, flashy costumes and makeup, and suspending Charli in midair with a harness. As Charli begins to have severe doubts about the tour's quality, Celeste is fired after voicing concerns about Charli's mental health. Mid-rehearsal, Tammy, along with Atlantic's legal team, rush in to confront Charli and her team, informing them that not only did Charli's post falsely advertise the benefits of the credit card, many of her fans committed fraud for those benefits, effectively both voiding the deal and bankrupting Howard Stirling. Facing severe backlash on social media, Charli disappears. Six days later, while in a meeting with Atlantic, Charli's managers and assistant realize she hasn't been seen or heard from since the Howard Stirling controversy. Fearing that she may be dead, they rush to her London home and are relieved to find she had simply taken another break. Once again returning to rehearsal, Charli records a lengthy voice message apologizing to Celeste, admitting that she has grown tired of
Brat following its extreme popularity despite her desire to be widely liked by others. She says that despite the tour being completely mutated from its original vision, she has decided to perform anyway as its poor quality will force the album cycle to be over. The film ends with a trailer for Johannes's bastardized
Brat Live! concert film. ==Cast==
