Seventeen-year-old Frankie is obsessed with what everyone else is thinking. She can keep up with the chatāfrom feminism to boys with tattoosābut when it comes to her own ideas, it's not so easy to hide her lack of confidence. With the help of her best friend, Haruna, Frankie forms a punk-rock girl band to attract the attention of Docāher spiky-haired, joint-smoking ex-boyfriend. She's got it all sorted: the Instagram page is live, the handmade posters are everywhere, and the band even has a first gig lined up (even if they are playing to a handful of retired bingo fans). But in her efforts to make the band a success and get Doc to notice her, Frankie starts to care less about what he thinks and more about how much she loves making very loud music. She finally feels a glimpse of who she can be, independent of anyone else. Then one day, Doc decides he is going to win her back...
