In the 1990s, 16-year-old Johanna Morrigan lives on a
council estate in
Wolverhampton with her aspiring rock star father Pat, exhausted mother Angie, brothers Krissi and Lupin, and two infant twins. Johanna dreams of escaping her life to become a writer, and finds comfort in speaking with the portraits of her idols covering her bedroom wall. A poem she wrote is selected for a televised competition, but she is overcome with nerves and humiliates herself on national television. After inadvertently revealing that her family is illegally breeding
Border Collies, resulting in her father losing his disability benefits, Johanna is determined to earn money for the family. Krissi refers her to
D&ME, a London music paper seeking a
rock critic, and Johanna submits a review of the
Annie soundtrack. She is invited to interview at the
D&ME offices, but arrives to learn the staff assumed her submission was a joke. Undeterred, she convinces them to give her a chance, so is assigned to cover the
Manic Street Preachers in
Birmingham. Eager to reinvent herself, Johanna adopts a new style, bright red hair, and the
pen name "Dolly Wilde". She attends her first rock show and falls in love with the music, immersing herself in the local scene.
D&ME agrees to send her to Dublin to interview musician John Kite, who is instantly smitten with her bubbly personality. She spends the day with John, who brings her onstage with him. Afterward, they open up to one another about their lives, and Johanna finds herself enamored with him. Returning home, Johanna writes a glowing feature on John, which her editor dismisses as the work of a teenage girl with a crush. Realising that negative criticism is the path to success, she begins writing deliberately cruel reviews as Dolly. Now a scathing but popular critic, Johanna is able to support her family with her writing income. She becomes sexually active, forcing Krissi to listen as she recounts her sexual exploits. Pat, still hoping to achieve fame with his band Mayonnaise, gives his
single to Johanna to promote. She brings it to a
D&ME gathering where it is derided by the others, who force her to
skeet shoot the record. At a music industry event, Johanna receives an award for "Arsehole of the Year", and runs into John. She drunkenly confesses her feelings for him and tries to kiss him, but he kindly rejects her advances. The next morning, Johanna writes a piece about his life, including deeply personal details he told her in confidence. She quits school, leading her parents and Krissi to confront her over her increasingly delinquent behaviour, but she cruelly reminds them that her money is supporting the family. Johanna goes to a party with her coworkers, where she accepts a full-time position at
D&ME, but overhears them badmouthing her. Unleashing a tirade against their smugness and negativity, she quits and returns home to find John has called about her article, ending their friendship. Distraught, Johanna drinks and cuts her wrist with a
drawing compass, but is knocked unconscious when her "Arsehole" award falls on her head. Recovering at the hospital, she reconciles with her family. To make amends, Johanna tries to apologise to every musician she criticised. She writes a piece on
self-harm, and is hired by
The Face magazine to write her own column, "Building a Girl". Finding John, Johanna apologises for her article, and shows him her original writing about him. She also gives him her newly cut-off hair as a token of apology. John forgives her, and says that while they may not be in a relationship anytime soon, he is happy to be her friend. Breaking the
fourth wall, Johanna tells the audience that a girl can always reinvent herself for the better. ==Cast==
