David hates school, where he has been bullied, has reached sixth form with no friends. Music is the only thing that keeps him going. Inspired by his hero, Karl Williams, he becomes vegan, wears eyeliner and writes song lyrics. But one night onstage Karl Williams accuses Muslims of homophobia and is cancelled. Conflicted by his feelings for his favourite artist and compelled by the conversations he has while playing Call of Duty, David becomes fascinated by the far right's narratives of masculinity. Living in the same East London borough as David, Hassan has his own problems. He is drifting apart from his childhood friends, Mo and Ibrahim. Determined to make something of himself, he volunteers for his local mosque and works hard to try to get the grades he needs to go to university. As these second-generation immigrants struggle for a sense of identity and belonging - amid a wave of online radicalisation and extremism - their fates become inextricably, catastrophically entwined.
