A girl goes missing somewhere in Ystad. It is obvious that she has seen something terrible and that someone wants her silenced. At the same time, a trial of human traffickers begins.
A young woman is killed and robbed in her apartment. The trail leads to her indebted ex-boyfriend, a bouncer. In the investigation, the police officer Pontus notices that his colleague is nervous. Isabell carries around a dark secret: one of the suspects, in this case, has a means of pressure against her in her hand. Commissioner Wallander has a great deal on the capable young policewoman, whose loyalty to her fatherly superior is subjected to a hard test of endurance.
A choir of young women gives a guest performance in a country church outside Ystad. But when an 18-year-old member of the choir disappears, Wallander is brought in to investigate.
Homes are being burgled in Ystad and three neighbors form their own vigilante group. Soon Wallander is convinced the group has committed a double murder, although no bodies have been found.
When a young boy disappears from pre-school, Wallander joins a desperate search to find him. Suspicions immediately fall on a pedophile recently released from prison.
Kurt Wallander has bought a dream house by the sea, but his peace and quiet is soon shattered when a man is murdered and an explosion in one of Ystad's power grids shuts down the electricity in the whole city.
