Yasmine Ajam has fled her past in the rough Stockholm borough mountain town, reinventing herself as a trend spotter in New York City. One day, she receives a startling message: there are riots stirring on the streets of Stockholm, and they appear to be connected with the disappearance of her brother, Faadi. Following rumors that Faadi was radicalized and died fighting for ISIS in Syria, Yasmine returns to Stockholm to discover what really happened to her brother. There, she becomes entangled in a dangerous web of allegiances and violence that stretches far beyond the gangs on her childhood streets. Meanwhile, in London, Klara Walldéen has landed a job at a human rights research institute working on a report to predict the effects of privatization of police forces. When Klara travels to Stockholm to present her findings to European Union policymakers, her laptop is stolen along with one of her colleagues.
