Metin is a small time hustler in a Stockholm suburb, filled with big dreams but bogged down by the circular world of street crime. Things change when his secret diary becomes a hot item for a posh book publisher, and Metin must decide if he's really up to the challenge that is leaving his criminal life behind.
A young gang member is found dead, and the Beck group's investigation indicates that a drug network is behind it. Klas Fredén has been monitoring the network for a long time, and the Beck group - led by Alex Beijer - is most graciously allowed to work with the murder investigation in parallel. She will soon end up on a collision course with Fredén. Thus, Martin Beck, who is now head of department, is also involved in the case.
