6 year old Albin Landberg disappears without a trace from his kindergarten, and all of Ystad get involved in

the family's and the police's ever more desperate search for the boy. The clues lead Kurt Wallander and his colleagues to a convicted paedophile, newly released from prison after finishing serving his jail term. But also towards a series of revelations that turn out to be more horrible and complicated than any of them could ever imagine.

A motorcycle rider is found murdered by the police, and the trail leads them to a local MC Club. The Club uses other riders to smuggle drugs across the Öresund bridge. Wallander believes that players outside of the MC club are trying to claim the local drug market when all clues indicate that the victim was one of the couriers. Only when Wallander's colleague Isabel gets violently assaulted in her home does he understand the lengths they will go to to achieve their goal.
