Elisabeth and John John are raised in the same city, yet they live light years apart, separated economically, socially and culturally. That is until the day they start in the same high school class.
During a police intervention, a macabre discovery is made in the trunk of a car. Josef and Oskar find themselves in the line of fire of a seemingly cold-blooded killer. But things are not what they seem.
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.
